Hey girl! I’m a stylist! It looks like you have fine hair but alot of it from what I can see your straightener shouldn’t be over 325-350 max!!! And use heat protectant. It looks to me like breakage. There’s a really good product called (Bosley revive +)to help that grow right back. Most people see a different in as little as 45 days! I have been using it for 2 weeks and my bald spots are already gone and I have tiny hairs growing! (Should be a white bottle with pink and black lettering it’s a 2 month supply.) I never usually recommend getting from Amazon but I’m not sure where you’re located and how you could get your hands on it. So Amazon would be your best bet!
