Umm.. I think you should appreciate your hair and work with it not against it, but that's probably not what you want to hear since you posted this.
Anyways, here's what I heard works for some:
-MSM can help hair growth and for some, loosen curls.
-Coconut milk/cream + lime
-Coconut milk + lemon
-Baking soda rinse/paste
-Brushing can disrupt curl pattern..
Anyways, I don't know if any of those work.. Cuz I'm trying to avoid loosening mine..
