I comb my hair when it is wet and dry. Since finding this forum, I'm going to start combing LESS when my hair is DRY because excessive combing can cause breakage, split ends, and does not help in retaining length.I used to comb my hair with a regular comb, but now I comb my hair with a wide tooth comb when it is wet and dry. I sometimes use a fine tooth rattail comb for parting and smoothing (I comb slowly).
I have just started wearing my hair in a protective style (two french-like braids) since I have a lot of new growth and it helps me stretch my time to relax. I do rollersets after my hair has been relaxed or when I dont have as much new growth.
