Detangler is your friend when stretching. I am 5 weeks post relaxer. This is usually a hard week for me because this is when the matting, etc... happens. I am determined to go for 8 and not get a touch up next week, which will be week 6.
I'm learning that too. I'm at 8 1/2 weeks post trying to make it to 12 but the back of my hair is matting. I want to use my new SEDU to help straighten it out but I've already used it once for the week.
