Review title is It works [SEP] I like this! I was tired of going to get them tinted every two weeks so I ordered this based on reviews. It seems to work fairly well, it lasts about a month. I don't use an entire capsule (from another reviewer) I just dumped them all into a little glass jar and dip the dry brush in when I need to tint them and get only as much as I need and add a little of the developer into the little mixing bowl. I leave it on about 30 minutes each time. .The only thing is that I wish it were just a tad bit darker...  My hair is almost black so it's pretty dark and this can pull it off for about a month, sometimes less but it does the job. And for the price it's worth it I think.
