Absolutly I think you can fix relaxer damage.. Ive also always had a pull through,, from the time I was 8 yrs old till I recently discouvered this board. Yet my hair was still healthy , shiny, soft, ailky, thick and brastrap length. I think the reason my hair didn't break off into sheds is because I've always washed my hair every 2 or 3 days. kept it moistuized, slashed water on it constantly thruout the day, out of sheer luck invested in good quality silk sheet set, air dried my hair and barely every used heat......... LUCKILY. I must say I'm thankful I still have hair ono my head from yrs of relaxer pull troughs,, I got away with it but this is a big nono! However it does show you if you do take extra care of your hair,, especially with moisture and reduction of heat, you should be a-ok!
