I trimmed my hair almost two months ago to get rid of my brittle damaged ends. So, my hair is not much longer. The front of my hair is 6.5 inches. The back of my hair measured from the nape is 6 inches (after trimming it was only 4.75 inches). The back of my hair measured from the crown is 7.5 inches. Although I did not retain much length my hair feels much healthier and stronger. I am no longer using any commercial rinse out conditioners. I am still working on my regimen but that is the biggest change so far. Also, I thought my hair was all 4b but since I stopped using conditioners my hair is now a 4b,4a,3c mix but it is still mostly 4b.
