In the field of hair growth, the peptides that currently have more research and some clinical data support mainly include the following types:

Copper Peptide (GHK-Cu):
This is one of the most studied hair growth peptides. Research shows that it not only promotes wound healing but also increases the expression of vascular endothelial growth factor in hair follicles, thereby promoting hair growth. In some experiments, its hair growth effects are considered comparable to minoxidil.
Amino acid peptides such as acetyl tetrapeptide-3 and biotinoyl tripeptide-1 :
These ingredients can serve as nutrients needed for hair growth, helping to repair follicle cells when the scalp is damaged and activating the growth of new cells.
