Hexanediol is generally a lower-concern ingredient for seborrheic dermatitis when used in a properly formulated cosmetic. It mainly helps dissolve ingredients, condition the skin and support the formula, rather than acting as a treatment ingredient.

No reliable evidence found for this page shows that Hexanediol feeds Malassezia or treats seb derm. It can still be part of a product containing fragrance or stronger actives, so the complete formula matters more than this single name. Stop if the finished product repeatedly causes burning, itching or redness.
