About Capixyl
A patented hair-complex ingredient pairing a biotin peptide with a tetrapeptide—common in scalp serums marketed for thinning hair.
Capixyl combines Biotinoyl Tripeptide-1 (sometimes listed separately) with Acetyl Tetrapeptide-3 in a glycol base. Brands position it to support the appearance of denser, healthier-looking hair at the follicle level. It is a cosmetic active, not a drug—results are gradual and vary by person.
Where you will see Biotinoyl Tripeptide-1
Cosmetic labels list Biotinoyl Tripeptide-1 in the full INCI ingredient block on the back of the package. Concentration, pH, and the rest of the formula change how Capixyl behaves—always read the whole label, not just the hero claim on the front.
