Crescina Re-Growth HFSC is a cosmetic product for topical use. It contains the heart of the patented Crescina Re-Growth (cysteine, lysine, glycoprotein), which facilitates normal hair growth. A portion of the patented active substances (Cysteine, Lysine, Glycoprotein and Stem-Engine) are inserted into specific carriers that allow their gradual, continuous release into the head of the scalp. The proper functioning of the stem cells contained in the follicle is necessary for the growth of new hairs.
