Plantur 39 Caffein Shampoo *For hair over the age of 40 *Activates the roots during washing *Especially for fine, brittle hair Until menopause, a woman"s hair roots are protected based on high levels of female hormones (estrogen). After menopause, these hormone levels will decline and the impact of male hormones will increase. The consequence: The hair will grow thinner, fall out prematurely, and the scalp will become visible. The Caffeine in this shampoo prevents the hormone-induced exhaustion of hair production. During hair washing, the active ingredient penetrates all the way into the hair follicle (detectable after 120 seconds residence time). This shampoo intentionally contains weakly dosed hair conditioning agents to ensure that your style retains its volume. Please read product leaflet carefully before use.
