Why Is Biotin Good for Hair?

Biotin is a popular vitamin that supports healthy hair growth, as it contains sulphur and other components needed to create more collagen. Collagen is responsible for skin protection, along with nail and hair health. High collagen levels keep hair shiny and prevent fragile, split ends.

Biotin promotes hair growth by renewing the hair follicles that are already growing. While the body naturally produces biotin, adding more of the supplement to the diet can help hair grow thicker and fuller, thus giving it a healthier look. Biotoin is “likely safe” by WebMD standards, for those who take appropriate doses by mouth, and is typically safe during pregnancy and breastfeeding as well.

Biotin supplements are readily available to consumers and don't require a prescription for purchase. Most people get enough biotin in their diet and don't need the supplement. Biotin is naturally found in many foods such as liver, salmon, carrots and bananas. For those who don't get enough biotin based on the foods they consume, biotin supplements can often be used to treat a biotin deficiency. A biotin deficiency can lead to skin rashes, thinning hair or even hair loss. The supplement is also taken orally for brittle nails, skin rashes in infants, diabetes and mild depression.
