Introduction
Under normal circumstances, using niacinamide properly will not cause hair growth. However, improper use or having thin skin layers may potentially lead to hair growth. Niacinamide is a member of the vitamin B family and also serves as a nutrient. Clinically, niacinamide is commonly used to treat skin inflammations, stomatitis, glossitis, and similar conditions. Since this medication is not a steroid, it has relatively low irritation.
Under normal circumstances, using niacinamide properly will not cause hair growth. However, improper use or having thin skin layers may lead to hair growth. The details are as follows:
1. No hair growth
Niacinamide is a member of the vitamin B complex and also serves as a nutrient. Clinically, it is commonly used to treat inflammatory skin conditions, stomatitis, glossitis, etc. Since this substance is not a hormonal drug, it has low irritancy. Therefore, when used correctly under normal conditions, it generally does not cause excessive hair growth in the treated area.
2. Possible hair growth
If niacinamide is used for prolonged periods, excessively applied to the skin without proper cleansing, and especially if the skin's stratum corneum is thin or the individual naturally has dense body hair, the drug may over-stimulate the local area, promoting increased hair growth. However, such cases are rare. If related symptoms occur, simply discontinue use—no special treatment is required.
It is recommended to use niacinamide under the guidance of a physician. Some individuals may be allergic to this substance, and in such cases, its use should be avoided.
