I'm 10 weeks post, stretching to 15. Actually it's NOT HARD FOR ME. I guess because before, I accidentally stretched for almost a year. Only bad thing is I can't always have my roots as straight as I want them. BUT they make my hair look thicker.
8 weeks....was planning on stretching it out 'til 12...but i went to the indian market and grabbed some products to try, so i'm gonna try and hang in there until 16 weeks.
