Hair grows healthy and strong, the scalp has more tone and lower sebum production. Active ingredient It is enriched with Black cohosh extract, a perennial plant native to North America that inhibits the enzyme 5-alfa-reductase which transforms testosterone into dihydrotestosterone: by inhibiting this enzyme, it combats both androgenetic alopecia and the hyper-production of sebum, which may be associated with it. How to use: After shampooing, spread the product evenly over the scalp and massage in. Do not rinse off. Energizing products are specifically designed to solve problems of scalp and fragile hair that is prone to falling out, and to offer a preventive treatment for various forms of alopecia. The formulas are characterised by a high concentration of multipurpose active ingredients: the caffeine phytoceutical has been made even more effective by the presence of sirtuins and beta-glucans. Caffeine stimulates the scalps cellular metabolism, while sirtuins, which are also known as the proteins of longevity, carry out an effective antioxidant and anti-ageing action while invigorating and reinforcing the scalp. Last but not least, beta-glucans are natural polysaccharides that strengthen our immune system.
