Topical cosmetic treatment for physiological hair growth with patented Transdermal Technology thanks to which active substances, in particular the brand new complex of 12 Plate-Like Molecules, can penetrate the hair system not only through the transfollicular path (opening of the follicle) but also transdermally through the skin layers of the scalp (ex-vivo test with Franz Cells) assisted both by their low molecular weight and by the presence of enhancers. Since the 12 Plate-Like molecules are synthetic substances similar to the endogenous pepditic molecules naturally present in the hair system, they are responsible for physiologically and synergistically promoting hair growth. The additional components present in the formula are: the Re-Growth complex, the HFSC complex, 3 enhancers. Indicated in cases of thinning dependent on physiological and non-pathological causes. It does not act on completely atrophied follicles. In specific formulas for men and women.
