That persistent scalp itch? It’s often your body’s way of signaling something’s wrong. Common triggers include dandruff, psoriasis, fungal infections, allergic reactions, and even stress or sunburn.
Dandruff/Seborrheic Dermatitis: Use shampoos with ketoconazole or zinc pyrithione.
Psoriasis: Medicated shampoos and corticosteroids help; stress management is key.
