Alpecin Gray Attack Caffeine & Color Shampoo, 6.76 Fl Oz (Pack of 2)

It work very efective.from the first aplication.

I have been using it for a while and absolutely no difference in my hair very disappointed with it would never buy it again, also it’s about eight dollars more than the stuff I used to buy at target and that worked very well.

Perfect product for my gray slow change.

I've been using it every day for about 50 days now. My hair is light brown with quite a bit of gray, mainly on the sides. Didn't notice a color change until more than 30 days in. Seems like it is darkening my normal hair more so than the gray, but it is de-emphasizing the gray nonetheless. I'm going to continue using it to see where it this goes and maybe update this review after 6 months or so.Tips:*Be patient and don't expect quick results.*Don't be frugal. Use it generously every day.*Leave it in your hair at least 3-4 minutes, longer if you can.

I tried my husband's shampoo. Noticed a slight change after just one wash which was Great. However, if you have any allergies to fragrance (I do), this is not a good fit. Very strong odor left in hair and on skin after washing and it's not pleasant.

Used it daily for 3 weeks for 5 minutes each, 5 times a week, it helped zero for reduction of my grey, but it was a good shampoo.

doesnt work on me

Seemed very promising!!!Followed the directions exactlyUsed daily and even left the product in for a longer amount of time to achieve quicker results (as suggested in the product directions as well)The end result is absolutely no color change.In my opinion, this is a complete waste of money.
