Does brewers yeast stop hair loss?

While some small-scale studies and anecdotal evidence suggest that brewer's yeast may reduce hair loss and support hair growth, the overall scientific evidence is currently limited. Most available research on brewer's yeast and hair loss has been conducted on animals, not humans.

One human study, published in the journal "Mycoses," found that brewer's yeast improved hair regrowth in individuals with tinea capitis, a fungal infection of the scalp. Another study, published in the journal "Phytotherapy Research," reported positive effects of a combination of brewer's yeast and other ingredients on hair loss in women.

Other researchers, however, have not confirmed these findings. A review article published in the journal "Skin Appendage Disorders" concluded that there is a lack of high-quality clinical studies to support the efficacy of brewer's yeast for treating hair loss.

It's important to note that brewer's yeast is usually marketed as a dietary supplement and not specifically as a treatment for hair loss. As a dietary supplement, its role is to provide nutrients like B vitamins, chromium, and protein, which contribute to overall health and potentially indirectly impact hair health.

If you're considering using brewer's yeast for hair loss or other health concerns, talk to your doctor first. A healthcare professional can provide personalized advice based on your individual situation and any potential interactions with any medications or existing medical conditions.
