Curls become loose overnight?
Hi! I'm new here so I can only assume this is the right place to ask questions, I apologise if there's already been a question like this. So basically my hair is 3a/3b (tighter curls the more moves up my head) and I have issues with my curls falling out overnight? I personally prefer my curls tighter (I'm an Ashkenazic jew but I prefer when my curls are tighter as I feel like it embraces the culture I have in me) what could I do to combat this? I'be also attached an image of my hair, please also correct me if my hair typing is wrong I can't seem to group it correctly. I've ordered a satin bonnet, will that do the trick?
