Does an Oily Scalp Cause Hair Loss?

Quick answer: An oily scalp does not by itself cause pattern hair loss, but oil, sweat and yeast can lead to dandruff and itch, and an oily scalp makes thinning hair clump and look sparser; good cleansing helps comfort and appearance.
- Clumping: Oily strands separate, showing scalp.
- Cleansing: Regular gentle washing.
- Fullness: Volume products, cosmetic options.
