While there is no scientific evidence to support all of the claims, there are some nutrients in beer that may be beneficial for hair health.
The proteins in beer help to strengthen the hair shaft, making it less likely to break or fall out.
The yeast in beer helps to exfoliate the scalp and remove dead skin cells, which can help to reduce dandruff.
The maltose and sucrose in beer help to hydrate the hair, making it look shinier and healthier.
