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!

I using this shampoo since 3 years best shampoo for my hairs, the only problem I always has with is my hairs getting more dandruff, I hope the manufacturer add anti dandruff materials in new products.

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.

غير مفيد

I tried to apply it daily twise , however i noticed NO improvment. I must say, to my great disappointment, that it is a lie.

Not effective at all like the original one from Germany stores
