Answers to your questions
When should I use Alpecin Grey Attack Shampoo?
Grey Attack is ideal for men with their first signs of grey hair or slightly grey hair who want a quick colour result. It is best suited for natural hair ranging from light brown to black.
Warning: May cause violet discolouration on white hair.
Is Grey Attack Shampoo suitable for daily shampooing?
Yes, Alpecin Grey Attack Shampoo is suitable for daily hair washing. It effectively removes sebum and dirt from the hair and scalp, eliminating the need for an additional shampoo. For best results, leave Grey Attack on for 2–5 minutes from application to rinsing.
How long do I have to use Grey Attack and when will the first results be visible?
The result depends on the condition and amount of grey hair. The colour effect develops gradually and becomes noticeable after 3 weeks of daily use. For optimal results, leave Alpecin Grey Attack Shampoo on the scalp for 2–5 minutes, from application to rinsing. Both the colour effect and Caffeine absorption improve with longer exposure time.
