Acetyl Tetrapeptide-3 is a biomimetic peptide, a short chain of four amino acids that mimics the body's own signaling molecules. It is the active core of Capixyl™ and one of the best-documented actives against hair loss.
The peptide works deep in the hair follicle, where it stimulates production of collagen type III and laminin, the proteins that anchor hair firmly to the scalp. It also calms the low-grade inflammation around the hair roots and inhibits 5-alpha-reductase, the enzyme that converts testosterone into DHT. DHT is what makes follicles shrink, so hair grows thinner and eventually falls out.
The result is less hair loss, stronger hair growth and a healthier scalp.
