Alpecin Grey Attack Caffeine & Colour Shampoo for Men 1x 200ml | Gradually Darker and Stronger Hair | Controlled & Natural Looking Colour Effect for Less Greys | Against Thinning Hair

My boyfriend loves this. Says it makes his hair feel thicker and soft. Ive noticed a change in shade. Smells nice.

I’ve been using shampoo for a few weeks, and it’s okay—not amazing, but not terrible either. Pros: • It does reduce the appearance of grey hairs with consistent use. • Leaves my hair feeling soft and manageable. • The scent is pleasant and not too overpowering. Cons: • The results aren’t immediate—it took several washes to notice a difference. • Doesn’t completely cover grey; it blends them rather than hiding them entirely. • A bit pricey for what it delivers. Overall, it’s a decent product if you’re looking for subtle results, but don’t expect a total transformation. A good choice if you want something easy to use, but there are better options out there.

Yeah it kinda works to some degree. My hair is less grey but not so sure about the caffeine part

"Grey attack" shampoo which is supposed to "thicken" my hair through judicial use of science magic. Unfortunately the only good thing about this very expensive foam maker is that it acts as a shampoo. The claimed benefits do not exist - my hair are as thin as they were before and the beard becomes a whiter shade of pale with every wash. It lacks oomph as a man's product.

Quality product that does work!

It makes girls think you’re hot

Good product

I heard a lot about this Grey attack shampoo and seeing as I’m greying thought why not give it a go . Product arrived on time and very well packaged, instructions are easy to follow and for ease are on the back of the shampoo bottle itself. Ok , I have used this product/shampoo for the last couple of weeks and have to say I have not noticed anything regarding colour change .Now I have used this shampoo twice a day for the past two weeks mentioned and I leave the shampoo on for 3 minutes even though it’s states on the bottle 2 minutes however what I have noticed is my hair feels stronger which is one of the health benefits is states it does which is strengthening roots. So to sum up product in my opinion has strengthened my hair roots but I have not noticed any colour change to my hair not even the slightest. Product price is expensive and the shampoo bottle size is small . Great smell to my hair once washed which is also a positive. Would I buy again , Yes and my reason for this is because my roots feel stronger which has to be a huge plus In my opinion .
