DSM’s Alpaflor Edelweiss CB (INCI: Leontopodium Alpinum Flower/Leaf Extract), which has previously been found to impart skin protection, more recently has been shown to increase hair density and decreases hair graying.
More specifically, in skin care, the ingredient demonstrates strong antioxidant, free radical-scavenging and DNA protection properties, the company reports. It also stimulates key proteins including transglutaminase 1 and involucrin, which reinforce the cornified envelope. Furthermore, gene expression studies demonstrate its multi-targeted activity, up-regulating markers for: loricrin, involucrin, filaggrin, small proline-rich proteins (SPRRs), keratin 1 and keratin 10.
More recently, DSM found the active also benefits hair in terms of density and pigmentation. In an in vivo anti-hair loss study, after five months of product application, subjects demonstrated a 13% increase in hair density over the placebo; specifically, an increase in density was observed in 57% of volunteers treated with placebo and 90% of volunteers treated with the active.
Additionally, an in vivo study observed hair pigmentation after four months. Hair reportedly appeared darker, with 50% less gray, versus the placebo.
