"Biotin is a popular supplement that is often taken in order to improve hair and nail health. Some people also take biotin in order to try and improve the health of their facial hair, and it is sometimes marketed as a beard growth supplement.
So, does biotin actually help with beard growth?
There is no scientific evidence to support the claim that biotin supplements can help with beard growth. Anecdotally, some people report that taking biotin has helped them to grow a thicker and healthier beard, but there is no solid evidence to back up these claims.
While biotin won't hurt you, and it may even help with other aspects of your health, there is no evidence to suggest that it can help with beard growth. If you're looking for a way to improve your beard, your best bet is to focus on other factors, such as proper grooming and a healthy diet."
