Research Overview

Minoxidil

Minoxidil has extensive human evidence for scalp hair regrowth in androgenetic alopecia and is a standard comparator in hair-loss trials. Its follicle effects are thought to involve potassium-channel modulation, vascular changes, and prolongation of the growth phase.

Hexapeptide-9

Hexapeptide-9 appears in scientific and cosmetic literature related to wound repair, cell migration, and extracellular matrix support. The evidence base is smaller than for more established peptides, but it is a real research-backed cosmetic ingredient.
