According to dermatologists, peptides may be able to help improve the health of hair follicles and create an environment more conducive to hair growth, though they won't work as effectively as prescription medications or minoxidil. Experts recommend looking for specific types of peptides like copper peptides, signal peptides, and anti-inflammatory peptides that can strengthen hair, boost keratin production, and reduce scalp inflammation.

Why it matters

Hair loss and thinning hair are frustrating issues that affect a significant portion of the population, so any potential solutions that are safe and accessible are of great interest. While peptides may not be a miracle cure, they could provide a helpful boost for those dealing with early stages of hair thinning or shedding.

The details

Peptides are short chains of amino acids that act as cellular messengers, signaling the body to perform certain functions like repairing damage, reducing inflammation, or supporting healthy growth cycles. In hair care, topical peptides can help hydrate the scalp, reduce inflammation around follicles, and strengthen the hair shaft. This creates an environment more conducive to hair growth, though peptides won't work as effectively as prescription treatments or minoxidil for regrowth. Experts recommend looking for specific types of peptides like copper peptides, signal peptides, and anti-inflammatory peptides that can provide the most benefits for thinning hair.
