I use flat iron for my straight thin hair to keep them look in order, but it actually has resulted in excessive hair damage, as my hair looks fizzy and dry, even after applying a leave in conditioner. Although I have stopped using flat iron on my hair for almost a month now, but my hair do not show any positive signs. I have also increased the intake of vitamins in my diet, but it doesnât work on hair damage. Going to spas for a hair treatment doesnât sound feasible to me. Therefore, can some expert tell me, what else do I require to repair my damaged hair now?
