Is the Grey Attack Shampoo suitable for daily hair washing?
Yes, Alpecin Grey Attack Shampoo is suitable for daily hair washing. The shampoo should soak in for 2-5 minutes. The active ingredient 5,6-DHI accumulates in the hair during shampooing and reacts with the oxygen in the air to form a colour pigment. This creates a permanent colour effect that does not wash out but grows out with the hair.
As the hair gradually becomes darker over a few weeks, the shampoo can be used alternatively with our C1 Shampoo and Caffeine Liquid as soon as the desired colour result has been achieved to provide the hair with its daily dose of caffeine.
