Look for shampoos containing ingredients like pyrithione zinc, ketoconazole, salicylic acid, or coal tar. These ingredients help address underlying causes like fungal overgrowth or inflammation. Consider alternating between a medicated shampoo and a gentle, hydrating shampoo.

Itchy scalp without dandruff can be caused by dryness, sensitivity to hair products, allergic reactions, or even stress. Other possibilities include scalp psoriasis or eczema, even without visible flakes. Consult a dermatologist for a proper diagnosis.

Identify and eliminate potential irritants like harsh shampoos or styling products. Use a gentle, fragrance-free shampoo and conditioner, and try a scalp massage to improve circulation. If itching persists, see a doctor to rule out underlying medical conditions.

Dermatologists often recommend shampoos with anti-inflammatory or antifungal properties, such as those containing ketoconazole or selenium sulfide, depending on the suspected cause. They may also suggest topical corticosteroids for short-term relief of inflammation and itch. A proper diagnosis is key to selecting the right treatment.
