Many years ago when I was in my late 20's I had a curly perm done. That was when the curly perms were popular. Like maybe late 70's. I had always tried to make my hair smooth and strait and did not realise I had such curly hair. I had the larger size curls not the little ones. It turned out great. The reason I did not look like Ronald McD is because I did not brush it or comb it when it was dry only wet.
As far as it being dry it was not. I'm not sure what it will do to your curls since your hair is pretty curly to begin with. Mine was not. B4 finding this web site I was gonna get a perm too and my stylist said she didn't want to do it I had too much hair it would cost a fortune. Those 70's perms lasted for like a year!! My curls are not large ringlets like I want BUT I am making the best I can of what I have. Your curls look great like they are!
