Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Keratin peptides are derived from keratin, a structural protein found in hair, skin, and nails. Their use in supporting or treating hair loss or thinning is based on the premise that supplementing or applying keratin-derived ingredients may help strengthen hair fibers and improve hair appearance. There is some scientific support for the cosmetic benefits of keratin peptides: studies have shown that topical keratin treatments can temporarily improve hair strength, smoothness, and manageability by filling in gaps in the cuticle and coating the hair shaft.

However, evidence for keratin peptides actually preventing or treating hair loss or promoting new hair growth is limited. Most clinical studies focus on topical effects rather than oral supplementation, and the improvements are largely cosmetic rather than addressing underlying causes of hair thinning or loss. A few small studies suggest that keratin peptide supplementation may improve hair tensile strength and reduce hair breakage, but these studies are often limited in size and duration. There is currently insufficient robust scientific evidence to support the use of keratin peptides as an effective treatment for hair loss or significant hair thinning.

In summary, while keratin peptides may provide some benefit in improving the appearance and strength of existing hair, their efficacy for actually treating hair loss or thinning is not well supported by current scientific research.
