A study by the Charité university clinic in Berlin has shown that absorption of the active ingredient increases for a period of up to 30 minutes that the product is left on the scalp. After that, penetration via the skin surrounding the follicles has increased to such an extent that additional caffeine availability is ensured for up to about eight hours. See similar questions...
