Collection: Soothing the scalp

Itchy scalp (pruritus) is a symptom resulting from dryness, barrier dysfunction, dandruff/pseudodermatitis, atopic dermatitis, psoriasis, allergic contact dermatitis, or infections (e.g., lice, fungal infections), among others. Treatment: gentle cleansing, avoidance of irritating detergents and hot water, anti-inflammatory/keratolytic shampoos appropriate for the cause (e.g., with zinc pyrithione, ketoconazole, salicylic acid), and scalp emollients; if itching persists, or if redness, scales, pustules, or hair loss occur, consult a dermatologist. Diagnostics may include dermatoscopy and patch testing. Source: Derm Net Diagnoses of Scalp Rashes.
