Help! My hair is damaged and I don’t know what to do to fix it :(

My hair was fine but the last two times I’ve straightened my hair it’s made the curls go away. I washed my hair yesterday after having it straight for almost about 5 days and now strands of hair are completely straight with NO curl 😞... I’ve chopped all my hair off before because it was severely damaged after trying to die it blonde (on my own 😬) but don’t wanna chop it all off again. Can anyone give me some ideas on what to do? Thanks 🙏🏽

It feels soft when I straighten it, the front pieces and the ends of the back feel SO brittle!! And when I brush my hair, I get a lot of breakage — dry or wet. 😑😔😭

**edit**

I know a lot of people are saying to stop using heat but that’s obvious lol. I need a solution to fix my hair. Definitely not using heat on my hair again!
