Isn't the alcohol harmful?

First of all, alcohol is not unhealthy and has no negative effect on the hair. Due to alcohol, Plantur 39 Phyto-Caffeine Tonic is quickly absorbed and transports the active ingredients even through fatty skin layers. This is important, if Plantur 39 is to be used on a daily basis without washing the hair every day. Water alone cannot do this, it would drip off.
