FunctionConditioning

What it is — Niacin (INCI: Niacin), also called nicotinic acid, is the free-acid form of vitamin B3. It is related to niacinamide but behaves a little differently on skin.

What it does — It is used as a conditioning ingredient, and on the scalp it is sometimes associated with a warming or temporary flushing sensation as it is applied. Descriptions here are cosmetic rather than medical.

Typical use — It appears in scalp tonics and conditioning formulas, usually at low levels within a wider blend.

Who it suits / good to know — Because the free-acid form can feel warming or tingly for some people, those with reactive skin or scalp may prefer to introduce it gradually. It is a supporting ingredient rather than a standalone treatment.

Safety — DHALIORA grades it low risk: a well-tolerated B-vitamin. This reflects the ingredient in general and is not medical advice; patch-test if your skin or scalp is easily irritated.

Why we grade it Low: Low risk - B-vitamin/derivative, soothing and well tolerated.
