What are the benefits of niacinamide for hair?
Many people see niacinamide as a way to regain voluminous hair. But it is not a direct stimulator of hair growth, even though it does contribute to the overall health of the hair, says the expert. By improving the condition of the scalp, supporting moisture retention and improving the structure of hair strands, niacinamide indirectly helps create an environment conducive to healthy hair growth. Here are some benefits:
1. Niacinamide is good for scalp health
Niacinamide helps maintain a healthy scalp by promoting better blood circulation and reducing inflammation.
2. Niacinamide helps with fluid retention
Niacinamide improves the moisture content of hair strands, prevents dryness and minimizes breakage. Well-hydrated hair is more resilient and less susceptible to damage.
3. Niacinamide strengthens the hair
By improving the hair’s protein structure, niacinamide contributes to stronger, more resilient locks, reducing the risk of breakage and split ends.

For women who color their hair, niacinamide can help maintain vibrancy by protecting it from any environmental damage.

Niacinamide can be incorporated into a hair care routine through various products such as shampoos, conditioners, serums or masks. All you need to do is look for products specifically formulated with niacinamide. Apply niacinamide-containing products to your scalp and hair, focusing on massaging them into the roots. Incorporate it into your routine two to three times a week for optimal results, the expert suggests.

apply it directly to the scalp.
