For the first time in my life I have decided to let my relaxer stretch for 16 weeks. So far it's been close to 8 weeks since my last relaxer. I noticed about 2 weeks ago that my scalp has begun to itch like crazy! I wash my hair 2x a week and deep condition it everytime it's washed. I decided to get cornrows 3 days ago and my scalp seems to be itching and tingling more than before. Does this mean hair growth? I also started taking biotin and msm about three weeks ago. Could this have something to do with this itching as well?
