Plantur 39 Phyto-Coffeine Tonic protects the hair root and strengthens hair growth. Premature hair loss is a worrying development not only in men, but also in women. Once menopause sets in, 3 in 4 women experience increased hair loss. And if nothing is done about it, this will inevitably lead to bald spots. The caffeine in the tonic prevents hair growth from slowing down after menopause.
