It seems I have been using Just for men for 20 years. I was salt and pepper at age 38. I guess prematurely gray. But I always have had the same problem. When to use it, so it doesn't look like I just colored my hair. I want it to stay the color all the time. But no matter what, it looks darker the next day.
Anyway, I was hesitant to use this new autostop, but had a few weeks off for Christmas, so since I didn't have to be anywhere, I tried it. I panicked when my hair turned completely black during the first ten minutes, but then read that it will appear darker during application.
But I still have the same problem. When to apply it. I am sitting here with a box in my hand, wondering if I should begin the process, since I applied it 3 weeks ago. Will it be darker tomorrow? I like the new applicator though. Seems much easier. I do my entire hair and not just the sides anymore.
