Can collagen supplements promote hair growth?

While collagen supplements are marketed as having the ability to enhance hair growth, there is currently no scientific evidence that collagen supplements stimulate hair growth directly. Now, there's evidence that collagen may improve the health of your scalp indirectly, using the amino acids provided by collagen, which may support healthy hair follicles. Still, they do not stimulate hair follicles to grow. Additionally, biotin and other nutrients have stronger evidence of effects on hair than on collagen.

Collagen operates through indirect mechanisms in supporting hair. Amino acids may improve blood flow in the scalp or have an anti-inflammatory response. These may lead to a better environment for existing hair and do not induce new hair growth. The results from these would vary significantly when compared to well-established hair growth nutrients.

When it comes to real hair issues, make sure you opt for evidence-based treatments. Multiple studies on biotin supplementation show validated outcomes. Medical treatments, such as minoxidil, are FDA-approved for the treatment of pattern baldness. Dermatologists are better equipped to handle continuous problems with hair loss than collagen.

Set expectations regarding collagen's hair benefits. It doesn't actually promote new growth, but it may improve texture and help prevent breakage. New growth requires additional adjustments. Third-party tested collagen will provide skin and joint benefits regardless, so ensure that you focus on that trustworthy benefit, not hair benefits that lack a body of evidence.
