Hair loss affects 50% of men and 30% of women at some point in their lives, making it a widespread dermatological concern. PRP (Platelet-Rich Plasma) hair treatment is an evidence-based, minimally invasive regenerative medicine application that stimulates hair follicles using growth factors derived from the patient's own blood. In this comprehensive guide, we present all the details of PRP hair treatment based on the experience of Virtuana Clinic (Izmit/Kocaeli).
What Is PRP Hair Treatment?
PRP (Platelet-Rich Plasma) hair treatment is the application of plasma — separated by centrifuge from the patient's own venous blood, with platelet concentration raised to 3–8 times that of normal blood — to areas of hair loss via micro-injection. Growth factors released by platelets (PDGF, VEGF, TGF-β, EGF) stimulate hair follicles, extend the anagen phase, and support new hair growth. Clinical studies report a hair density increase in 70–80% of patients receiving PRP hair treatment.
| Feature | Detail |
|---|---|
| Procedure time | 45–60 minutes |
| Blood draw | 15–60 ml venous blood |
| PRP volume | 5–10 ml |
| Injection depth | 1–2 mm (dermal papilla level) |
| Number of sessions | 3–6 sessions (initial) |
| Session interval | 2–4 weeks |
| First results | After 2nd–3rd session |
| Full results | 6–12 months |
| Maintenance | Every 4–6 months |

Types of Hair Loss and PRP Suitability
The efficacy of PRP hair treatment varies significantly by the type of hair loss; androgenetic alopecia (AGA) is the best-responding condition, while it is ineffective in conditions such as cicatricial (scarring) alopecia where the follicle is permanently damaged. Making the correct diagnosis before treatment increases the success rate by 40%.
| Type of Loss | PRP Suitability | Success Rate | Notes |
|---|---|---|---|
| Androgenetic alopecia (male pattern) | Very suitable | 70–85% | Best indication |
| Androgenetic alopecia (female pattern) | Very suitable | 65–80% | Best results at Ludwig I–II |
| Alopecia areata | Suitable | 60–70% | More effective during stable period |
| Telogen effluvium | Suitable | 55–65% | With treatment of underlying cause |
| Traction alopecia | Conditionally suitable | 40–50% | More effective in early stages |
| Cicatricial alopecia | Not suitable | <10% | Follicle completely damaged |
| Alopecia totalis/universalis | Not suitable | <5% | Autoimmune process dominant |
Comparison of PRP Preparation Methods: Single Spin vs Double Spin
The method of PRP preparation directly affects the platelet concentration, leukocyte content, and thus the clinical efficacy of the product. The two main methods, single spin and double spin centrifuge techniques, produce PRP products with different cellular compositions. According to the 2025 meta-analysis, the single spin method shows a slight advantage in hair treatment.
Single Spin Method
The single spin method separates blood into plasma and cellular components in a single centrifuge process.
- Centrifuge speed: 1,500–3,000 RPM
- Duration: 5–10 minutes
- Platelet recovery: 60–80%
- Platelet concentration: 2–4 times baseline
- Leukocyte content: High (L-PRP obtained)
- Advantages: Simpler, faster, high platelet recovery
- Disadvantages: More leukocytes (inflammation potential)
Double Spin Method
In the double spin method, plasma is separated in the first centrifuge, then platelets are concentrated in the second centrifuge.
- 1st spin: Low speed (1,200–1,500 RPM, 10 min) → Plasma separation
- 2nd spin: High speed (3,000–4,000 RPM, 15 min) → Platelet concentration
- Platelet recovery: 40–60%
- Platelet concentration: 4–8 times baseline
- Leukocyte content: Low (P-PRP obtained)
- Advantages: Higher platelet concentration, fewer leukocytes
- Disadvantages: Longer duration, lower recovery, more complex
2025 Meta-Analysis Results
| Parameter | Single Spin | Double Spin | Difference |
|---|---|---|---|
| Platelet count | Higher recovery | Higher concentration | Slightly in favor of single spin |
| Hair density increase | 32% (average) | 28% (average) | Statistically insignificant |
| Terminal hair count | Slightly higher | Slightly lower | Minimal difference |
| Vellus hair count | Lower | Higher | In favor of single spin |
| Patient satisfaction | 75% | 72% | Similar |
Effect of Centrifuge Speed and Duration on Platelet Count
Centrifuge parameters are the most important determinants of PRP quality; speed (RPM) and duration directly affect platelet recovery, concentration, and cell viability. Optimal parameters should raise platelet concentration 4–6 fold while maintaining cell viability above 90%.
Optimal Centrifuge Parameters
| Method | 1st Spin Speed | 1st Spin Duration | 2nd Spin Speed | 2nd Spin Duration | Result |
|---|---|---|---|---|---|
| Low-speed single spin | 1,500 RPM | 5 min | - | - | 2–3× concentration |
| Mid-speed single spin | 2,500 RPM | 8 min | - | - | 3–4× concentration |
| High-speed single spin | 3,500 RPM | 10 min | - | - | 4–5× (cell damage risk) |
| Standard double spin | 1,200 RPM | 10 min | 3,500 RPM | 15 min | 5–8× concentration |
| Gentle double spin | 1,000 RPM | 8 min | 2,500 RPM | 10 min | 4–6× (best viability) |
Speed-Quality Relationship
- Too low speed (<1,000 RPM): Insufficient separation, low platelet concentration
- Optimal speed (1,500–3,000 RPM): Best platelet recovery and viability
- Too high speed (>4,000 RPM): Platelet damage, premature activation, low growth factor release
Growth Factor Cocktail: PDGF, VEGF, TGF-β, EGF
PRP's mechanism for stimulating hair growth is based on the action of more than 30 growth factors released from platelets on dermal papilla cells and stem cells. Each growth factor contributes to follicle revival through a different mechanism. These growth factors normalize disrupted signaling pathways in hair loss.
Key Growth Factors and Functions
| Growth Factor | Concentration in PRP | Effect on Hair | Mechanism |
|---|---|---|---|
| PDGF (Platelet-Derived Growth Factor) | 15–30 ng/ml | Dermal papilla cell proliferation | Fibroblast proliferation, collagen synthesis |
| VEGF (Vascular Endothelial Growth Factor) | 5–15 ng/ml | Increased perifollicular vascularization | Angiogenesis, increased nutrient transport |
| TGF-β (Transforming Growth Factor Beta) | 20–40 ng/ml | Follicle cycle regulation | Stem cell activation, catagen regulation |
| EGF (Epidermal Growth Factor) | 2–8 ng/ml | Epidermal cell growth | Keratinocyte proliferation |
| FGF (Fibroblast Growth Factor) | 5–10 ng/ml | Follicle development | Anagen phase extension |
| IGF-1 (Insulin-like Growth Factor 1) | 50–100 ng/ml | Hair shaft growth | Cell survival, antiapoptotic |
| HGF (Hepatocyte Growth Factor) | 1–5 ng/ml | Follicle regeneration | Mesenchymal stem cell stimulation |
Role of PDGF
PDGF is one of the most important growth factors in PRP hair treatment:
- Provides 200–300% proliferation of dermal papilla cells
- Thickens the dermal papilla by increasing collagen synthesis
- Increases oxygen and nutrient flow to perifollicular tissue
- Supports miniaturized follicles in returning to the terminal phase
Role of VEGF
VEGF strengthens the perifollicular vascular network that nourishes hair follicles:
- Triggers formation of new capillary vessels (angiogenesis)
- Increases permeability of existing vessels
- Increases nutrient and oxygen transport to follicles by 40–60%
- Compensates for reduced vascularization in androgenetic alopecia
- Slows follicle miniaturization
A-PRP vs L-PRP: What Is the Difference?
PRP is divided into two main categories by leukocyte content: L-PRP (Leukocyte-rich PRP) and P-PRP / A-PRP (Pure PRP / Advanced PRP, leukocyte-poor), and the efficacy of both in hair treatment is debated. Both forms have been shown to provide clinical benefit in hair treatment; L-PRP provides stronger inflammatory stimulation, while A-PRP provides a gentler regenerative effect.
| Parameter | L-PRP (Leukocyte-rich) | A-PRP / P-PRP (Leukocyte-poor) |
|---|---|---|
| Leukocyte content | High (3–5× baseline) | Low (below baseline) |
| Platelet concentration | 3–5× | 4–8× |
| Inflammatory response | Strong | Mild |
| Growth factor release | Rapid, high peak | Slow, sustained |
| Post-procedure pain | More | Less |
| Swelling | Moderate | Minimal |
| Ideal indication | Early-stage alopecia, alopecia areata | Advanced AGA, sensitive scalp |
| Preparation | Single spin (usually) | Double spin or special kit |
Clinical Preference
- Alopecia areata (autoimmune): L-PRP preferred (immunomodulatory effect)
- Early-stage AGA: Both are effective
- Advanced-stage AGA: A-PRP preferred (higher platelet concentration)
- Post-hair transplant: A-PRP preferred (less inflammation)
- Sensitive scalp: A-PRP preferred
Hamilton-Norwood and Ludwig Classification with PRP Success Rates
The Hamilton-Norwood system is used for men and the Ludwig system for women in staging hair loss, and PRP treatment success rates vary significantly by stage. As a general rule, success rates are 80%+ in early stages, while they fall below 30% in advanced stages.
Hamilton-Norwood Classification (Male)
| Stage | Definition | PRP Success Rate | PRP Role | Additional Treatment |
|---|---|---|---|---|
| Norwood I | Minimal loss | 90%+ | Preventive | Minoxidil optional |
| Norwood II | Mild frontotemporal recession | 85% | Therapeutic | Finasteride optional |
| Norwood III | Pronounced "M" shape | 75% | Therapeutic | Finasteride + minoxidil |
| Norwood III Vertex | Vertex loss beginning | 70% | Therapeutic | Combined medical treatment |
| Norwood IV | Frontotemporal + vertex expansion | 55% | Supportive | Hair transplant to be considered |
| Norwood V | Large loss area | 35% | Limited support | Hair transplant recommended |
| Norwood VI | Scalp island | 20% | Minimal effect | Hair transplant + PRP |
| Norwood VII | Advanced baldness | <10% | Ineffective | Hair transplant |
Ludwig Classification (Female)
| Stage | Definition | PRP Success Rate | PRP Role |
|---|---|---|---|
| Ludwig I | Mild crown area thinning | 80–85% | Primary treatment |
| Ludwig II | Pronounced crown thinning | 65–75% | Primary + supportive |
| Ludwig III | Advanced thinning, scalp visible | 40–50% | Supportive |
How Is PRP Hair Treatment Applied?
PRP hair treatment is a systematic procedure consisting of blood draw, centrifuge process, PRP activation, and scalp injection. Total procedure time is 45–60 minutes and no surgical cutting instruments are used. At Virtuana Clinic, all PRP applications are personally performed by our specialist physician.

Microneedling + PRP Protocol
Microneedling (dermaroller or dermapen) combined with PRP is a synergistic protocol that increases PRP penetration into the scalp and provides additional collagen stimulation. Studies show that the microneedling + PRP combination provides 30–40% more hair density increase compared to PRP alone.
Combined Protocol
- PRP preparation: Standard centrifuge protocol
- Scalp cleaning: Antiseptic application
- Microneedling: With dermapen at 0.5–1.5 mm needle depth over the entire loss area
- PRP application: Immediately after microneedling, PRP is poured topically over the scalp
- Massage: Gentle massage to ensure PRP absorption through micro-channels
- Additional injection: PRP injection to specific areas if needed
Microneedling Parameters
| Parameter | Value | Description |
|---|---|---|
| Needle depth | 0.5–1.5 mm | According to area and skin thickness |
| Speed | Medium-high | Dermapen device setting |
| Number of passes | 3–5 passes | Per area |
| Endpoint | Pinpoint bleeding | Indicator of adequate depth |
| Contraindication | Active infection, keloid |
Clinical Data
- PRP alone: 30% increase in hair density (average)
- Microneedling alone: 15% increase in hair density
- Microneedling + PRP: 45–55% increase in hair density
- Synergistic effect: Mechanical stimulation + growth factor combination
ACell/PRP Combination Treatment
ACell (extracellular matrix), when combined with PRP, is an advanced regenerative treatment that reconstructs the tissue surrounding hair follicles and increases stem cell activation. This combination provides 20–30% higher hair density increase compared to PRP alone.
What Is ACell?
- Full name: ACell MatriStem (Extracellular Matrix — ECM)
- Source: Biological tissue scaffold derived from porcine bladder submucosa
- Mechanism: Structural scaffold supporting tissue renewal + stem cell stimulating signals
- FDA status: Approved for wound healing, off-label for hair treatment
ACell + PRP Protocol
- ACell preparation: ACell in powder form is suspended in sterile saline
- PRP preparation: Standard centrifuge protocol
- Mixing: ACell suspension + PRP are combined
- Injection: Applied using standard PRP injection protocol
- Session interval: Every 4–6 weeks, total of 3–4 sessions
ACell + PRP vs Standard PRP
| Parameter | Standard PRP | ACell + PRP |
|---|---|---|
| Hair density increase | 30% | 45–55% |
| New terminal hair | Moderate | High |
| Thickness increase | 15–20% | 25–35% |
| Onset of effect | 2nd–3rd session | 1st–2nd session |
| Cost | Standard | 40–60% higher |
| Evidence level | High | Moderate |
Post-Hair Transplant PRP Protocol
PRP applied after hair transplantation (FUE/FUT) is a supportive treatment that increases graft survival, accelerates healing, and reduces the risk of shock loss. The combination of hair transplant + PRP increases the graft survival rate by 15–20%.
Protocol Timing
| Period | PRP Application | Purpose |
|---|---|---|
| Pre-operation | 1 session 2–4 weeks before | Increasing scalp blood supply |
| During operation | PRP bath for grafts | Preserving graft viability |
| Post-operation month 1 | 1 session | Accelerating healing |
| Months 2–3 | 1–2 sessions | Reducing shock loss |
| Month 6 | 1 session | Growth stimulation |
| Month 12 | 1 session | Maintenance |
| Thereafter | Every 4–6 months | Long-term support |
How Many Sessions Does PRP Hair Treatment Require and Results
The initial protocol for PRP hair treatment generally consists of 3–6 sessions, applied at 2–4 week intervals. First results begin to appear 2–3 months later and full results emerge within 6–12 months.
Session-by-Session Progress
| Session | Time | Expected Change | Dermoscopic Finding |
|---|---|---|---|
| Session 1 | Week 0 | No visual change yet | Baseline evaluation |
| Session 2 | Week 4 | Decrease in shedding rate | Increased perifollicular circulation |
| Session 3 | Week 8 | First fine hairs visible | Vellus hair increase |
| Session 4 | Week 12 | Increase in hair thickness | Terminal hair increase beginning |
| Session 5 | Week 16 | Pronounced density increase | Follicle thickening |
| Session 6 | Week 20 | Satisfying results | 30–40% increase in hair density |
| Maintenance | 6–12 months | Preservation of results | Stable dermoscopic findings |
Dermoscopic Result Follow-Up
Dermoscopy (trichoscopy) is a diagnostic method used to objectively monitor the efficacy of PRP treatment, evaluating hair and scalp structure with magnified images. This method allows treatment results to be measured 60% more accurately compared to subjective evaluation.
Follow-Up Parameters
| Parameter | Measurement | Expected Improvement | Measurement Timing |
|---|---|---|---|
| Hair density | Hairs/cm² | 30–40% increase | Every 3 months |
| Hair diameter | Micrometers | 15–25% increase | Every 3 months |
| Vellus/terminal ratio | Ratio | Shift toward terminal | Every 6 months |
| Perifollicular vascularity | Visual score | Increase | At each session |
| Yellow dots | Number/area | Decrease | Every 3 months |
| Single hair units | Percentage | Decrease (multiple unit increase) | Every 6 months |
PRP vs Scalp Mesotherapy
PRP and scalp mesotherapy are treatment methods both applied by injection to the scalp but working through different mechanisms; PRP contains autologous growth factors while mesotherapy contains a vitamin, mineral, and drug cocktail. In clinical comparisons, PRP provides 20–30% higher hair density increase compared to mesotherapy.
| Criterion | PRP | Scalp Mesotherapy |
|---|---|---|
| Active substance | Autologous growth factors | Vitamin, mineral, drug cocktail |
| Source | Patient's own blood | Ready-made solutions |
| Allergy risk | None (autologous) | Low but present |
| Hair density increase | 30–40% | 15–25% |
| Number of sessions | 3–6 | 6–10 |
| Session interval | 2–4 weeks | 1–2 weeks |
| Evidence level | High | Moderate |
PRP vs Hair Transplantation
PRP and hair transplantation are two different complementary approaches in hair loss treatment; PRP strengthens existing hair and slows shedding, while hair transplantation transfers new hair to areas of loss. 45% of patients have both methods applied in combination.
| Criterion | PRP | Hair Transplantation (FUE) |
|---|---|---|
| Mechanism | Stimulating existing follicles | New follicle transfer |
| Ideal stage | Norwood I–IV | Norwood III–VI |
| Procedure time | 45–60 min | 6–10 hours |
| Recovery | 0 days | 7–14 days |
| Time to results | 2–6 months | 12–18 months |
| Permanence | Maintenance required | Permanent |
PRP vs Minoxidil and Finasteride
PRP, minoxidil (topical), and finasteride (oral) together form the three pillars of hair loss treatment. Because each has a different mechanism of action, combined use produces synergistic results.
| Treatment | Mechanism | Efficacy | Use | Side Effects |
|---|---|---|---|---|
| PRP | Growth factor stimulation | 30–40% density increase | Injection every 2–4 weeks | Minimal |
| Minoxidil 5% | Vasodilator, anagen extension | 25–35% density increase | Topical 2× daily | Scalp irritation (10%) |
| Finasteride 1 mg | 5α-reductase inhibition | 30–40% density increase | Oral 1× daily | Sexual side effects (2–5%) |
| Triple combination | Synergistic | 50–65% density increase | All together | Combination risk low |
Female vs Male PRP Hair Treatment
PRP hair treatment is effective in both female and male patients, but the loss pattern, hormonal factors, and treatment approach differ by sex. PRP response rate in women is reported as 65–80%, and in men as 70–85%.
Female-Specific Approach
- Loss pattern: Diffuse thinning (Ludwig)
- Hormonal evaluation: Ferritin, thyroid, DHEA-S, testosterone checks
- Additional treatments: Minoxidil 2%, iron supplementation, biotin
- PRP dose: Standard (same as male)
- Session frequency: Every 4 weeks (adjustable according to hormonal cycle)
- Special conditions: Postpartum shedding, post-menopausal
Male-Specific Approach
- Loss pattern: Frontotemporal recession + vertex (Norwood)
- Hormonal evaluation: DHT level
- Additional treatments: Finasteride, minoxidil 5%
- PRP dose: Standard or slightly higher
- Injection focus: Frontotemporal line and vertex area
- Special conditions: Early-onset (20s) AGA
Biotin and Nutritional Support
Nutritional support applied together with PRP treatment provides the building blocks needed for hair growth, improving treatment outcomes by 15–25%. In particular, deficiencies in biotin, zinc, iron, and Vitamin D can worsen hair loss and reduce PRP response.
Recommended Supplements
| Supplement | Daily Dose | Function | Deficiency Prevalence |
|---|---|---|---|
| Biotin (B7) | 2.5–5 mg | Keratin synthesis | 38% (in hair loss patients) |
| Zinc | 15–30 mg | Follicle division | 30% |
| Iron (Ferritin) | Ferritin >40 ng/ml target | Oxygen transport | 72% (in women) |
| Vitamin D | 2,000–4,000 IU | Follicle cycle | 65% |
| Omega-3 | 1,000–2,000 mg | Anti-inflammatory | 45% |
| Vitamin B12 | 1,000 mcg | Cell division | 20% |
| Selenium | 55–100 mcg | Antioxidant | 15% |
Dietary Recommendations
- Protein: 1.2–1.5 g/kg per day (hair structure consists of 95% protein)
- Iron-rich foods: Red meat, spinach, lentils
- Zinc sources: Pumpkin seeds, red meat, chickpeas
- Biotin sources: Eggs, almonds, avocado
- Water: 2–3 liters daily
PRP Hair Treatment Side Effects
Because PRP hair treatment is an autologous product derived from the patient's own blood, the risk of allergy and infection is extremely low. The most common side effects are mild pain at the injection site (40–60%), temporary swelling (20–30%), and redness (15–25%), all of which resolve spontaneously within 24–48 hours.
| Side Effect | Frequency | Duration | Management |
|---|---|---|---|
| Injection pain | 40–60% | During procedure | Topical anesthesia |
| Sensitivity | 30–50% | 24–48 hours | Paracetamol |
| Mild swelling | 20–30% | 24 hours | Resolves spontaneously |
| Redness | 15–25% | 12–24 hours | Cold compress |
| Temporary hair shedding | 5–10% | 2–4 weeks | Normal (telogen effluvium) |
| Headache | 5–10% | 24 hours | Analgesic |
| Infection | <0.1% | - | Antibiotic |
PRP Hair Treatment Contraindications
Although the contraindications for PRP hair treatment are limited, certain medical conditions may affect the safety or efficacy of the treatment.
Absolute contraindications:
- Thrombocytopenia (platelet count <100,000/µL)

- Smoking should be reduced/stopped
- Plenty of water should be consumed (hydration improves platelet quality)
- Hair should be clean (product-free)
- Should not come on an empty stomach (light breakfast recommended)
After Procedure (24–48 hours)
- Do not wash hair (first 6–12 hours)
- Do not use harsh shampoo (1 week)
- Do not use hair dryer (48 hours)
- Avoid intense exercise (24 hours)
- Do not consume alcohol (24 hours)
- Protect from sun (1 week)
- Do not have hair colored (1 week)
Frequently Asked Questions (FAQ)
1. Does PRP hair treatment really work?
Yes, the efficacy of PRP hair treatment has been proven by numerous randomized controlled studies and meta-analyses. A 70–80% increase in hair density and 85% reduction in shedding have been reported in patients. The best results are achieved in early-stage androgenetic alopecia (Norwood I–IV, Ludwig I–II).
2. How many sessions does PRP hair treatment require?
Initial treatment generally consists of 3–6 sessions, applied at 2–4 week intervals. Thereafter, maintenance sessions are recommended every 4–6 months. Total treatment duration and number of sessions are personalized based on the severity of hair loss.
3. Is PRP hair treatment painful?
Most patients describe pain as "2–4/10" (mild). Pain is significantly reduced with topical anesthetic cream or nerve block. Post-procedure scalp sensitivity can last 24–48 hours and is managed with paracetamol.
4. When does PRP hair treatment show results?
First results begin to appear at 2–3 months (after the 2nd–3rd session). Full results emerge within 6–12 months. A reduction in shedding is generally noticed earlier than an increase in density.
5. Is PRP hair treatment permanent?
PRP treatment alone is not permanent because it does not eliminate the underlying cause of hair loss. Maintenance sessions every 4–6 months are required to preserve results. With regular maintenance, results can be sustained for years.
6. Is single spin or double spin PRP more effective?
According to the 2025 meta-analysis, the single spin method shows a slight advantage in hair treatment (higher platelet recovery, similar clinical results). However, the difference is not statistically significant and both methods are effective.
7. Is PRP hair treatment effective in women?
Yes, PRP is also effective in women. The success rate in women at Ludwig I–II stages is 65–80%. In women, the diffuse thinning pattern requires PRP to be applied over a broader area.
8. Can PRP and hair transplantation be done together?
Yes, PRP and hair transplantation are complementary treatments. PRP is used in scalp preparation before transplantation, for graft protection during the operation, and for healing support afterward. It increases the graft survival rate by 15–20%.
9. Is ACell + PRP superior to standard PRP?
The ACell + PRP combination provides 20–30% higher hair density increase compared to standard PRP. However, its cost is 40–60% higher and the evidence level is not yet as strong as standard PRP.
10. What are the side effects of PRP hair treatment?
Because PRP is an autologous product (from the patient's own blood), the risk of side effects is very low. The most common are: injection pain (40–60%), mild swelling (20–30%), redness (15–25%). The rate of serious complications is below 0.1%.
11. How effective is the microneedling + PRP combination?
The microneedling + PRP combination provides 30–40% more increase in hair density compared to PRP alone. Micro-channels facilitate PRP reaching the dermal papilla and provide additional collagen stimulation.
12. Can minoxidil be used during PRP treatment?
Yes, PRP and minoxidil show synergistic effects when used together. The vasodilatory effect of minoxidil facilitates PRP growth factors reaching the follicle. The triple combination (PRP + minoxidil + finasteride) can provide 50–65% density increase.
13. Is biotin supplementation necessary with PRP treatment?
Although not mandatory, biotin deficiency is detected in 38% of patients with hair loss. Biotin supplementation (daily 2.5–5 mg) can improve PRP results by 10–15% by supporting keratin synthesis.
14. Can PRP hair treatment be done during pregnancy?
PRP hair treatment is generally not recommended during pregnancy. There is insufficient safety data. For postpartum hair loss, PRP can be initiated 3–6 months after delivery.
15. Why is dermoscopic follow-up important in PRP hair treatment?
Dermoscopy allows objective evaluation of treatment results. Numerical tracking of parameters such as hair density, diameter, vellus/terminal ratio, and perifollicular vascularity is of critical importance for demonstrating treatment efficacy and adjusting the protocol if necessary.
