How long should hair be processed while getting a perm? My stylist uses some unidentifiable white goop in a bowl when she relaxes my hair, so I don't know what brand of relaxer it is or how long the process time should be. She's pretty fast and my hair is very thick, but it only takes her about 5 or 6 minutes for her to apply the relaxer over my roots 2 times and then smooth it with her fingers 2 or 3 times. The minute she's done smoothing it she rushes me over to the sink. Is 6 minutes long enough, or is my hair getting underprocessed? Is getting underprocessed bad?
