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

This shampoo is basically just a weak portion of hair dye mixed into shampoo. You have to leave it on for 5 minutes every day, which makes no sense when you could just use regular hair dye once every month or two and get real results. It did nothing for my gray hair, and it even risks leaving stains in the shower and on pillowcases. Definitely not worth it.

Pretty good. Gets rid of most of the Grey and looks natural doing it gradually. Seems like there are just some that it can't penatrate. Would be nice if there was a conditioner as well but doesnt really seem to dry the hair.

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.

No obvious effect actually. Hair is still white.

Good
