How to Tell Them Apart
Dandruff flakes are larger, oily and yellow-tinged, and the scalp often feels oily and itchy. Dry-scalp flakes are smaller, white and powdery, and the scalp feels tight and dry — often worse in winter or with harsh shampoos.
What Causes Each
Dandruff is linked to excess sebum and Malassezia yeast. Dry scalp results from dehydration, cold weather, hard water, over-washing or stripping products. Identifying which you have determines the fix.
The Right Treatment
For dandruff: anti-fungal/clarifying shampoos and a scalp detox to clear buildup. For dry scalp: hydrating masks, gentler cleansing and a nourishing hair spa. Persistent flaking with redness may need a dermatologist.
