Alpecin Grey Attack Shampoo Product Information
Alpecin Grey Attack contains the active ingredient 5,6-dihydroxyindole (DHI), a chemical compound which reacts with the oxygen in the air to form a colourant on the hair, offering a natural and long-lasting darkening effect with consistent use.
Alpecin Grey Attack also contains a caffeine complex that increases circulation and allows nutrients to be delivered to the hair follicles. This, in turn, encourages hair regrowth and ensures healthy roots.
Alpecin Grey Attack contains caffeine, which is absorbed through the scalp and hair shaft to stimulate the hair roots directly at the follicle level, promoting hair growth and strengthening the hair.
The shampoo also includes a colour-effect formula designed to gradually build up colour pigments on the hair fibres, darkening greying hairs with regular use and helping to restore a more youthful appearance.
The combined effect of caffeine and the colour-effect formula is to improve both the strength and the look of hair over time.
Apply Alpecin Grey Attack by wetting the hair, massaging the shampoo into the scalp and hair, leaving it on for 2‑5 minutes and then rinsing thoroughly. This product works best for light brown to black hair.
Once treated hair has reached the desired colour, the frequency of application can be reduced to a few applications per week, alternating between Alpecin and your regular shampoo.
Please note that Alpecin Grey Attack will not become more effective when used more than once per day.

Alpecin Grey Attack Shampoo is available over the counter, so a prescription is not necessary to purchase it.
Alpecin Grey Attack Shampoo can be used by men alongside Finasteride and Minoxidil (Regaine for Men Extra Strength Foam or Regaine for Men Extra Strength Solution) as part of an effective combined strategy to treat hair loss.
Similarly, women can use Alpecin Grey Attack Shampoo alongside Regaine for Women Extra Strength Scalp Foam or Regaine for Women Regular Strength Solution to treat hair loss.
If you are using Alpecin Grey Attack Shampoo with Regaine products, follow these steps for best results:
- Apply Regaine (Minoxidil) Foam or Regaine Solution to the scalp daily, leaving it on the scalp for at least 15 minutes so it absorbs properly.
- Once it has absorbed, massage Alpecin Grey Attack Shampoo into the scalp and hair, leaving it for at least 2‑5 minutes before rinsing thoroughly.
Men who are using Alpecin Grey Attack Shampoo alongside Finasteride should take Finasteride daily as per the dosage instructions in the patient information leaflet that comes with the medication.
Alpecin Grey Attack is able to restore dark colour to the hair when repeatedly applied. It also contains a caffeine complex that can strengthen hair roots and slow down the process of hair loss.
The efficacy of Alpecin Grey Attack varies on an individual basis. Alpecin is not designed to completely ‘reverse’ grey hair, but to change the appearance of hair with consistent use.
Results will be visible sooner for some individuals, but typically appear after 2 to 4 weeks of daily application when the shampoo is used properly and left in the hair for 2‑5 minutes during each application.
