considering the restrictions this might work, I find my hair always curls up when I don't brush it right after a shower so braiding it and waiting would do the trick

I tried starting from simple, and made one big braid, and waited until it dried, without leaving overnight. Of course my first result was far from perfect, but even with this poorly made try, i did get a visible change in waviness. So i now want to experiment more, make tighter braids, leave them overnight.

Thank you very much for recommending me this :3

This is a great method. I was friends with some horse girls as a teen and I let them braid my hair to practice for the horses. I was so curly back then 💖

This method looks very simple, and is easy to improve effect by using curling lotion and keeping braids overnight. I will obviously try it, but i dont know whether it is an effective method to make hair curly, to later use it with curly girl method.
