The scalp is one of the areas of the body with the highest density of hair follicles and sebaceous glands. Due to this characteristic, it is highly susceptible to conditions such as dandruff, seborrheic dermatitis, and psoriasis. In 2026, our understanding of the pathophysiology of these conditions has deepened and treatment options have expanded.
Dandruff: Common but Often Underestimated
Dandruff is a condition characterised by excessive flaking of the scalp, affecting approximately fifty percent of the population. While it was long considered a purely cosmetic issue, the underlying mechanisms are now understood to be more complex.
Causes
- Malassezia fungi: These break down sebum on the scalp to produce oleic acid, which triggers an inflammatory response in susceptible individuals.
- Barrier dysfunction: Disruption of the lipid structure in the stratum corneum.
- Microbiome imbalance: Loss of balance between bacterial and fungal flora.
2026 Treatment Approaches
Antifungal shampoos (ketoconazole, ciclopirox) remain the first-line treatment. However, in 2026 microbiome-friendly formulations have come to the fore. Scalp care products containing prebiotic and postbiotic ingredients aim to support healthy flora balance and reduce recurrence. Preparations containing zinc pyrithione and selenium sulfide also maintain their place among effective options.
Seborrheic Dermatitis: Beyond Dandruff
Seborrheic dermatitis is a more severe and inflammatory form of dandruff. It presents with redness, itching, and greasy scaling. Beyond the scalp, it can also affect the eyebrows, the sides of the nose, and the chest area.
Triggering Factors
- Stress and fatigue
- Seasonal changes (especially winter months)
- Hormonal fluctuations
- Weakened immune system
- Excessively oily diet
Treatment Strategies
In mild cases, antifungal and anti-inflammatory shampoos may be sufficient. In moderate-to-severe cases, short-term topical corticosteroids or calcineurin inhibitors (tacrolimus, pimecrolimus) are used. In 2026, topical formulations containing JAK inhibitors are being evaluated as a promising alternative for controlling inflammation without steroid use.
In chronic and resistant cases, phototherapy and systemic antifungal treatments may be required.
Scalp Psoriasis
Psoriasis is a chronic condition characterised by rapid skin cell turnover due to an overactive immune system, resulting in thick, silver-white scaly plaques. The scalp is one of the most frequently affected areas in psoriasis.
Features of Scalp Psoriasis
- Thick, adherent, silver-coloured plaques
- Ability to extend beyond the hairline to the forehead and behind the ears
- Severe itching and sometimes pain
- Potential contribution to hair loss if left untreated
2026 Current Treatment Options
Topical treatments occupy the first line of care: combinations of calcipotriol and betamethasone, coal tar preparations, and salicylic acid-based keratolytics are frequently used.
For moderate-to-severe cases, narrowband UVB phototherapy is an effective option. Comb-type UV devices designed specifically for the scalp have made treatment more practical.
For widespread and resistant scalp psoriasis, biologic therapies come into play. IL-17, IL-23, and TNF-alpha inhibitors can achieve significant improvement by targeting the immune mechanism. In 2026, oral selective TYK2 inhibitors are becoming increasingly established in clinical practice as an alternative to biologic therapies.
The Importance of Accurate Diagnosis
Dandruff, seborrheic dermatitis, and scalp psoriasis can closely resemble each other. An incorrect diagnosis leads to ineffective treatment and prolonged suffering. Dermoscopic examination, biopsy when necessary, and a detailed patient history are of critical importance in arriving at the correct diagnosis.
The Virtuana Clinic Approach
At our clinic, scalp conditions are addressed from a multidisciplinary perspective. Dermoscopic evaluation, microbiome analysis, and dermatological consultations when needed guide us to the most accurate diagnosis. Treatment plans are personalised according to the patient's lifestyle, triggering factors, and severity of the condition. Long-term management and relapse-prevention strategies form an integral part of the treatment. Please contact us for personalised pricing information.
