Biotin is a B vitamin that plays an important role in keeping hair, skin, and nails healthy. It helps the body convert food into energy and supports keratin production, which is essential for strong hair and nails. While biotin is found in many foods, it is also available in supplements and haircare products and many include it in their routine to help improve hair strength, reduce nail breakage, and support overall skin health.

This guide gives you a closer look at what biotin does and how it can benefit you.

What Is Biotin?

Biotin, also known as vitamin B7 or vitamin H, is a water-soluble B vitamin that helps the body convert food into energy. It plays a key role in keratin production, the protein that forms the foundation of hair, skin, and nails. While it’s naturally present in many foods, some people turn to supplements or biotin-infused products to give their body an extra boost.

How Biotin Supports Hair, Skin & Nails

1. Hair Growth & Strength

Biotin is often associated with thicker, stronger hair. While it doesn’t directly stimulate new hair growth, it helps support the health of hair follicles, reducing breakage and keeping strands resilient. Those with biotin deficiency may notice increased hair strength and improved texture when they get enough of this vitamin.

2. Healthy, Resilient Nails

Brittle, peeling nails can be a sign of weak keratin structure. Biotin helps reinforce nail strength, reducing breakage and splitting. Studies suggest that regular biotin intake can lead to thicker, more durable nails over time.

3. Skin Health & Hydration

Skin cells rely on biotin for proper function. A deficiency can sometimes lead to dryness, irritation, or imbalances. While biotin alone isn’t a magic fix for skincare concerns, getting enough of it supports a healthy skin barrier, helping maintain hydration and smoothness.

Incorporating Biotin Into Your Routine

Most people get enough biotin through their diet, but some may need an extra boost. Here are a few simple ways to maintain healthy levels:

• Biotin-Rich Foods -  Eggs, nuts, seeds, fish, dairy, and whole grains naturally contain biotin.
  

• Balanced Nutrition -  A varied diet with plenty of vitamins and minerals helps support overall skin and hair health.
  

• Biotin-Infused Products - Some hair and skincare products contain biotin to strengthen hair and improve skin texture. Read on below as we explore some of our favourite biotin products available in our collection!
