My hair is really dry, embarrassingly dry. I'm 4a/4b natural. I've always had dry hair but now it's crispity dry. I had my hair blown dry and flat ironed two weeks ago and it was the softest it had ever been. I thought that porosity might have been the issue but because it was the softest ever when it was straightened I'm thinking that might not be the cause. The whole reason the hair would be porous is because the cuticles are open and not lying flat so maybe straightened hair would accommodate better settings for hair that was originally porous?
