The Science
Hair loss (alopecia) involves the progressive miniaturization of hair follicles, driven by DHT sensitivity (androgenetic alopecia), inflammation, oxidative stress, and reduced growth factor signaling. Peptides that support hair growth work by promoting the transition of follicles from the resting (telogen) to the active growth (anagen) phase, stimulating growth factors that support follicle health, reducing scalp inflammation, and improving blood supply to follicles.
