Scalp Flaking & Dandruff: Causes, Treatments & Solutions
Scalp flaking is extremely common and usually caused by dandruff (seborrheic dermatitis), dry scalp, or product buildup. However, persistent or severe flaking may indicate conditions like scalp psoriasis, fungal infections, or eczema. Understanding the type of flakes and accompanying symptoms helps identify the right treatment.
Quick Answer
Dry scalp produces small, white, dry flakes without oiliness. Dandruff (seborrheic dermatitis) produces larger, yellowish, oily flakes with scalp redness. Dandruff is caused by yeast overgrowth; dry scalp by lack of moisture.
