Acetyl Tetrapeptide-3
Scalp density
A four-amino-acid peptide often paired with biotin peptides in scalp-density formulas.
Acetyl Tetrapeptide-3 appears in EU cosmetic databases with hair-conditioning functions. Suppliers claim it supports dermal papilla cells—the part of the follicle that signals growth. Usually one piece of a multi-ingre…
Capixyl
Scalp density
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 …
