Hey ! You are such a pretty girl!! I hope you enjoy your natural hair journey. But I would advice you to STEP AWAY FROM THE STRAIGHTEN. When I was transitioning I did a lot of Bantu knots and roller sets. I think the sets along with no heat and good treatments ( moisture and protein) will help remind your hair it's curly .. But I do think you might want to cut it. Healthy hair or long hair? What do you want more ?
