The Benefits of Biotin for Hair

You may have been hearing more lately about a haircare ingredient called biotin for hair growth. Many health and beauty brands have begun adding it to shampoos, conditioners, stylers and leave-in treatments. If you haven’t tried it, you’re probably wondering “What does biotin do, exactly?” or “What are the benefits of biotin?” Let’s start by looking at what this hair supplement is.

What is Biotin?

Like the majority of fortifying beauty ingredients, biotin occurs naturally in the body, and we also get it from foods like eggs, nuts and red meat. Technically, it’s a water-soluble B vitamin (B7, which is also called vitamin H) that can either be taken as a dietary supplement in capsule form or added to haircare products. It is known to synthesize protein and encourage the production of keratin, which is a vital building block of our hair follicles. So, when you see haircare products like biotin shampoo for hair growth or biotin oil for hair, you know they contain a natural topical enhancement that contributes to healthier locks.

One of biotin's primary benefits is its ability to maintain hair growth. It's a wise choice for anyone with thinning or fine hair looking to improve their hair's overall health and appearance.

Unlock Your Hair's Shine

Biotin stimulates keratin production, strengthening and smoothing hair follicles. This allows hair to better reflect light, giving it a shinier appearance.
