Hair-Strengthening Peptide (Biotinoyl Tripeptide-1)

Biotinoyl Tripeptide-1 is a specialized peptide conjugated with biotin, widely used in cosmetic formulations for its hair- and lash-conditioning, strengthening, and density-supportive benefits. Designed to support the look of fuller, healthier hair, it helps improve the appearance of hair anchoring and resilience by conditioning the scalp environment and reinforcing the hair fiber, contributing to reduced breakage and improved thickness perception over time. Frequently positioned in “hair growth support” and anti-hair loss concepts, Biotinoyl Tripeptide-1 is commonly incorporated into scalp serums, tonics, shampoos, conditioners, leave-in treatments, and lash/brow products, typically at low use levels and formulated for optimal stability and tolerance across scalp and skin types.
