Hey there! From my little experience of being a curlie, I can tell you to first stop straightening your hair! If it is damaged, then you might want to first focus on making it healthy. You can check out the Curly Girl Method and try it out if you choose to. If not, you need to slowly go back into being a curlie... Search for products that make your curls more defined!

That's mostly what i have to say, but if that was not useful at all, here are some links that may help you!

Transitioning - CurlTalk

(other people going from straight -> curly)

Curly Hair Tips, Styles & Products - NaturallyCurly

(find out more about your hair so you can care for it/style it the way you want!)

All About the No Shampoo Method

(Curly Girl Method if you're interested!)

Hope that helped!
