I have curly hair and am wondering if I have damaged my hair, and whether it'll grow back strong and be how it used to be. I first straightened my hair at 12, and then didn't until the age of 14. I only straighten my hair once ever 2-3 months, or whenever I feel like it. I am now 17 and straighten my hair every 1-2 months to change up my style. It never occurred to me to use heat-protectant, until my dad mentioned it, and now I am an anxious mess. I read the side effects of not using heat protectant and am scared that my hair is just going to get weaker and fall out. I have to straighten my hair when cutting it because my curls are all different lengths.
Is too late to start using it, and if any damage has been caused, can it be repaired? Also which heat protectant should I use? I know the roots are with me, meaning that my hair grows fine and i produce plenty of keratin, but now I'm doubting myself. My mum said my hair is okay, and not too damaged and that has sent me over the edge into a panicked frenzy. She also said that hair protectants have chemicals in them and she doesn't want me using them, but I am freaking out.
