The ‘hero serum’ that started it all, our Follicle Boost Hair Density Serum works to stimulate the scalp, improve cell turnover and prevent hair loss and thinning. Independent user trial results over four weeks with 100 women and men found: - 76% agreed they noticed a reduction in hair loss - 75% agreed that their hair growth was boosted - 76% agreed that their hair felt thicker - 85% agreed their scalp felt healthier - 84% have made this an essential part of their haircare regime A true labour of love, this has been meticulously developed by our team of scientists, dermatologists and beauty experts and formulated to perfection in our German laboratories. Here’s how it works: special pumpkin seed extract and castor oil work to stimulate the scalp, with the former having been scientifically proven to help block an enzyme called 5-alpha reductase, which has been shown to produce a chemical called DHT from testosterone, which causes hair loss. Meanwhile, exfoliating retinol and lactic acid work to improve cell turnover and remove dead skin and debris that often inhibit hair growth. Gently massage a few drops onto the scalp every morning, as part of your daily skincare routine.
