It can be frustrating to have persistent scalp itching despite using antifungal shampoos like Selsun and Sobowash, especially when lice and dandruff have been ruled out. Your symptoms might be due to other causes such as scalp psoriasis, contact dermatitis (allergic reaction to hair products), or dry scalp unrelated to fungal infection.

• Consider avoiding harsh shampoos or hair products that might irritate your scalp and switch to gentle, fragrance-free cleansers.
• Applying a mild corticosteroid scalp lotion or a soothing agent like aloe vera gel may help reduce inflammation and itching, but this should be done under a dermatologist’s guidance.
• If the itching continues or worsens, a dermatologist can perform a detailed scalp examination and possibly a biopsy or patch testing to identify less common causes.
