I am glad I found this too! I think my hair is starting to grow in straighter since I was pregnant. My daughter is now 5 months old and I am breastfeeding-so I still have different hormones running around. I hope it gets curly again! I know most of these posts are older-but I have a question! I thought curly hair was curly because of the shape of the hair follicle. So why do hormones play such a role in it? They don't change the shape of the follicle do they?
