Procapil is a trademarked complex combining biotinyl-tripeptide-1, apigenin, and oleanolic acid, marketed to strengthen hair anchoring and counter follicular miniaturization linked to DHT and aging. It is used in topical scalp and hair products as an active aimed at reducing hair shedding and promoting hair retention.
