Blazing, I was having a similar problem. I have patches of hair that are a different texture than the rest of my hair. Actually, it's damaged and takes forever to grow, but since I changed my diet, drank more water and got more sleep, my hair has started growing again. And my hair is started to grow in with my natural texture, instead of the damaged texture. If you use good hair products and handle your hair gently, then this last step should help. Also, the satin pillowcase is also a good idea. As far as diets go, eat regularly and eat more lean protein and limit refine grains and sugar and caffeine.
