That constant itch on your scalp isn’t just annoying — it’s your body telling you something’s off. “Whether it’s stress, an imbalance in oil production, or harsh hair products,” several triggers can lead to scalp irritation.

1. Dandruff, Dermatitis & Psoriasis
Dandruff and seborrheic dermatitis are common causes. “Those small, flaky white bits” are often linked to oil buildup or irritating products. Seborrheic dermatitis causes greasy, yellow flakes and redness. Scalp psoriasis, an autoimmune condition, creates thick, scaly patches that can bleed. Use shampoos with ketoconazole or zinc pyrithione, and consult a dermatologist if symptoms last over two weeks.

2. Fungal Infections & Lice
Ringworm causes redness, flaking, and hair loss. “Follow a full course of oral antifungal medication.” Lice, often overlooked in adults, cause intense itching, especially behind the ears. Treat with anti-lice shampoo and wash bedding thoroughly.
