I used to have beautiful, thick wavy hair that dried perfectly by itself. I lost a lot of hair after going through labor and now it is kinky, frizzy, and pretty much lifeless. I have never colored it and I only blow dry it at most a few times a week. Will my hair return to its same texture once the hair has grown back in (my hair dresser said she could feel some regrowth) or do you think this is permanent? All help is appreciated!
