How it's thought to work
Supports the skin barrier and calms redness.
What the research says
Strong skin data; hair-specific studies are small.
How it's used
Leave-on scalp serums.
Barrier care versus follicle treatment
Niacinamide is used in skincare for barrier support and is included in some leave-on scalp products. A calmer-feeling scalp may help someone stick with a routine, but that is not the same as reversing pattern hair loss. Human evidence for niacinamide as a stand-alone regrowth treatment remains limited.
Choosing a tolerable formula
If your scalp reacts to fragrance, exfoliants or a drug vehicle, review the entire ingredient list rather than assuming niacinamide itself solves irritation. Introduce one new formula at a time. Persistent redness, scale or pain deserves a diagnosis; FOLIGAIN® or another cosmetic brand cannot substitute for that assessment.
The good and the not-so-good
A quick, balanced look before you decide whether it belongs in your routine.
