Question: Do you offer Alpecin shampoo in your treatment regimes? If not, why?
Answer: Alpecin is a shampoo, which would be heavily diluted with water when applied to the scalp (in the shower or bath). It is unlikely that any of the product would be absorbed into the scalp to stimulate the hair follicles.
Aside from this fact, there is currently no significant evidence that caffeine has prevention properties for hair loss in humans. In previous lab tests, caffiene was seen to block DHT (the hormone that causes genetic hair loss) when applied directly to individual hair follicles, but these conditions are very different to those when washing your hair with a shampoo.
There are however treatments that are proven to prevent and reverse hair loss. Find out about them here.
