Grey Attack Caffeine & Colour 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.

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.

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.

Alpecin Grey Attack Shampoo helps to darken hair. However, depending on your original hair colour, the result may not meet expectations—for example, if previously blonde hair appears darker.

Warning: May cause violet discolouration on white hair.
If unwanted discolouration occurs, discontinue use immediately.

Alpecin Grey Attack Shampoo is not a traditional colourant and can be used without concern for discolouration. It does not stain the scalp or hands during hair washing.

To prevent discolouration of surfaces such as the shower, washbasin, or towels, ensure that shampoo residues are rinsed off thoroughly. Once the hair has been rinsed and dried, no discolouration is expected.

Use Alpecin Grey Attack Shampoo daily, leaving it on for 2–5 minutes from application to rinsing. The colour effect intensifies with longer application times. Depending on your hair length and initial hair colour, the time it takes for the effect to become visible may vary slightly. Generally, the first results can be seen after 3 weeks of daily use.

Alpecin Tuning Shampoo is ideal for men who do not yet have grey hair or are just beginning to notice a few grey strands and want to conceal them. Its colour effect intensifies with each application but washes out with a normal shampoo, as the colour pigments only adhere to the hair's surface.

In contrast, the colour effect of Alpecin Grey Attack Shampoo is significantly stronger. It contains the active ingredient 5,6-DHI, which reacts with oxygen in the air to form colour pigments within the hair. This gradually darkens grey hair without creating a dyed appearance. Unlike Tuning Shampoo, the colour effect of Grey Attack does not wash out.

Alpecin Grey Attack Shampoo is specifically designed for scalp hair. However, the colour effect can also appear on beard hair if used consistently over a longer period and as the beard hair grows to a sufficient length.
