Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.
KPV, a peptide patented by L'Oreal, may promote hair growth and reduce hair loss by extending the anagen phase and has anti-inflammatory properties. It could be combined with treatments like minoxidil for enhanced effects.
Adipose-derived stem cell secretome showed significant improvement in hair density and growth, especially when combined with minoxidil, suggesting a synergistic effect. The study had limitations, including a small sample size and potential bias.
New potential hair loss treatment uses molecules from hairy moles to stimulate follicle growth. Topical solution requires less frequent application, like Botox injections a few times per year.
