MONPURE London Follicle Boost Hair Density Serum works to stimulate the scalp, improve cell turnover and help prevent hair thinning – while actively promoting thicker, fuller hair. The pioneering formula stars a special pumpkin seed extract which has been scientifically proven to help block an enzyme called 5-alpha reductase. This enzyme has been shown to produce a chemical called DHT from testosterone, which causes hair loss. Meanwhile, retinol and lactic acid work to improve cell turnover and remove dead skin and debris that often inhibit hair growth.
