A couple of year ago, I had two bald spots on the sides of my head from letting my friend sew in tracks, but then glue them in at the top. I wore this style continuously for about eight months. I would take it out, relax my hair, and get it done all over again. So when I was getting my hair braided one day, she said do you realize you have two bald spots? I was devastated after I looked in the mirror and I said right then and there that I was going to stop doing it. I got some ORS temple balm and I would say within about 2 months the hair was back, so it did work for me!
