I had wavy/curly hair when I first got pregnant, afterwards it kind of straightened. I had a perm, but didn't know there were different levels of perms & I got a "curly" perm & wound up looking like Annie (as someone else said earlier). The next time I got a perm, I asked for a "body" perm & it worked out great. That was probably 20+ years ago. As I have gotten older (and I have a 9 year old now), my hair has just gotten curlier & I no longer get perms. Your hair, since it started straight, might go back to being straight. The best suggestion is to get a good haircut for your hair. I now find it easier to just get a good cut with layers & just let it curl. I now do nothing to my hair after washing except use shampoo & conditioner for culy hair, scrunch with some gel & go. Sometimes I use hairspray to keep it from frizzing. My life is so much simplier than when I tried to curl it, or straighten it. Find a good hairdresser that can give you a cut for your hair. Being a mother of 4 and living on a farm, you need the simplicity the most!
