Biotinoyl Tripeptide-1

Biotinoyl Tripeptide-1 is a cosmetic active ingredient that conjugates biotinoyl (a derivative of biotin, vitamin B7) with the tripeptide GHK (glycyl-histidyl-lysine). While closely related to Biotin Tripeptide-1, this variant uses the biotinoyl form of biotin, which may offer improved stability and compatibility in certain cosmetic formulations. The peptide was developed to address hair loss and thinning by targeting multiple aspects of follicle health.

The mechanism of action involves dual functionality. The biotinoyl component provides a targeted form of biotin delivery to the hair follicle, supporting the metabolic processes necessary for keratin synthesis and hair shaft formation. Biotin is a cofactor for carboxylase enzymes involved in amino acid metabolism and fatty acid synthesis, both of which are important for healthy hair production. The GHK peptide component stimulates collagen synthesis, improves tissue remodeling, and supports the structural integrity of the connective tissue sheath that anchors the hair follicle.

Research on Biotinoyl Tripeptide-1 has focused on its ability to strengthen hair anchorage in the follicle, reduce premature hair shedding, and improve the overall quality of the hair shaft. By reinforcing the connection between the hair root and the surrounding dermal tissue, the peptide may help prevent the loosening of hair that leads to increased shedding during brushing and washing.

This ingredient is commonly found in anti-hair loss shampoos, conditioners, scalp treatments, and hair serums. It is frequently combined with other actives such as saw palmetto extract, caffeine, or other growth-stimulating peptides to create multi-targeted hair care systems. Products containing Biotinoyl Tripeptide-1 are marketed toward both men and women experiencing diffuse hair thinning.
