TETRAPEPTIDE-66

Description

Tetrapeptide-66 is an innovative peptide compound designed to address hair loss and promote hair growth. This synthetic biomimetic peptide consists of four amino acids strategically sequenced to mimic the effects of natural hair growth factors. It works by targeting the dermal papilla cells, which play a crucial role in hair follicle development and cycling.

The primary mechanism of action for Tetrapeptide-66 involves stimulating the production of essential proteins and growth factors within the hair follicle. This includes increasing the expression of keratin genes and boosting the synthesis of extracellular matrix proteins. These effects contribute to improved hair anchoring, enhanced follicle strength, and increased hair shaft diameter.

Clinical studies have shown that Tetrapeptide-66 can reduce hair loss by up to 13% and increase hair density by approximately 15% when used consistently over a period of four months. The peptide is typically incorporated into leave-on haircare formulations such as serums, lotions, or scalp treatments at concentrations ranging from 0.5% to 2%.

Tetrapeptide-66 is well-tolerated by most individuals and can be combined with other hair growth actives for synergistic effects. Its stability in formulations and ability to penetrate the scalp make it a valuable ingredient in advanced haircare solutions targeting thinning hair and hair loss.
