The positive effect of caffeine against hair loss was proven for the first time in 2004 by the Alpecin research team headed up by laboratory manager Dr. Klenk.
Spurred on by this breakthrough, Alpecin developed the first caffeine-based hair care products for men. Today, caffeine is the oldest known and most intensively researched agent against hair loss.
The energy-boosting agent goes directly to the hair roots when washing with a caffeine shampoo. Here the influence of DHT is blocked and, at the same time, hair growth is promoted.
The shampoo becomes effective when left on the scalp for 2 minutes. During this time, the caffeine builds up in the hair roots to form a depot which is sufficient for 24 hours.
This is why a caffeine shampoo must be applied every day. If use of the caffeine shampoo is interrupted or stopped, protection against DHT is lost and hair loss starts over again. Hair loss is reduced and the hair feels stronger after just three months of daily use.
If you don't have the time or motivation to wash your hair daily or if you want to complement use of the shampoo, suitable supplementary products can also help raise the caffeine level.
Caffeine liquids, such as tonics, are massaged directly into the scalp. Once applied they are not washed out.
