Do not buy this....use the regular shampoo-in Just For Men color! I have been using the regular shampoo-in Just for Men hair color for a couple years now and it has been awesome! I tried this new Auto Stop brush in gel today, and after leaving it on for just under 20 minutes, which is basically 10 mins longer than you need to, when I washed it, about 70 percent of it washed out! Very disappointed as the regular has always worked so well. Just stay with the regular!!
