Alpecin Gray Attack Caffeine & Color Shampoo, 6.76 Fl Oz

I have been using it almost everyday for a couple months. The bottom half of the hair has turned black. Somehow the tip is still grey. I believe most of the grey should go away after the next hair cut.

Does not work!!! I used it for 30 days complete garbage I must request a refund absolutely no change to hair color this is a scam and he must be driven out of business!!!

I took a Before & After photo of my Gray hair against my scalp. As you can see it is gone I wish it came in a bigger bottle. But you need 25 shampoos before you see the results. One bottle is about 12 shampoo.

Be prepared to do daily for at least 3 weeks to start to see affects (I actually let it sit on my head for 20-30 minutes a day). My hair and beard were while (cotton top) but now I do have some color. Its enough that I will be starting my 2nd bottle to see if I can get my head a satisfactory shade - my beard is going to take much longer. The really good thing: I was allergic to every other hair color product out there (even the ones that stated they wouldn't). This has been the only product that doesn't have me itching like crazy!

Works great, grey hair is tough for it, and it gradually gets it darker. The result is very natural, it’s great for men who don’t want to get noticed that they are coloring their hair

Great Product, really really works, my husband hair looks fantastic

Product does nothing to the hair color. Been using two-three times weekly, for three months, it has made Zero color change to my grey/salt n pepper hair color. What a ripoff, complete waste of money. 🤬🤬🤬

It really isn't that effective as a color shampoo. I used a whole bottle and the change was minimal at best. I use their regular caffeine shampoo and like it!! But I will go a different direction for hair coloring shampoo.
