Biotin is a vitamin that is often marketed as a supplement to promote hair growth. However, there is limited scientific evidence to support the idea that biotin can actually help with hair growth.
Some small studies have suggested that biotin supplements may improve hair growth in people with conditions that cause hair loss, such as alopecia areata. However, these studies are limited in scope and more research is needed to confirm these findings.
In general, biotin deficiencies are rare and most people consume enough biotin through their diet. Taking excessive amounts of biotin supplements can also cause side effects, such as acne and gastrointestinal issues.
Overall, while biotin may have some potential benefits for hair growth in certain circumstances, more research is needed to fully understand its effects. It is important to talk to a healthcare professional before taking any supplements or making changes to your diet.
