What the gurus are saying
The OS-01 peptide is the detail that keeps coming up, with experts saying it helps clear out aging cells that stir up scalp inflammation. Several describe less shedding and a light feel with no residue or minty tingle, though some are still hoping for regrowth rather than seeing it. Those who use micro-needling may want to stamp the serum on rather than roll it, since rolling over fragile strands could cut them.
