Review (1/5): Completely Ineffective
I tried this twice. The first day I warmed the mask for 30 seconds in a microwave, applied it to my hair, put on a plastic cap, and left it in for 6 hours. There was absolutely no effect whatsoever so the next day I did the same thing but only left it in for 5 hours.
But again, there was no effect at all.
I'm in my early 60's and use Just for Men hair color, but I'm lucky my hair is till very long, and not in that bad of shape. It's a bit dry and frizzy though, and I'm really surprised this product did nothing whatsoever to help.
