Hi Julie,
I'm at the stage where my hair is finally growing and I can't tell you how nice it is to see it again. I had really long hair all my life and to face the clippers was very scary I cryed all day leading up to it, then I took my 2 girls (8 & 5) with me so they could help cut it off. I did this so they would remember it as a fun day where they got to cut mums hair off not a day where their mum came home bald and crying. So anyway like the other ladies said its great in hot weather and when you go out you don't have to do it! I didn't wear a wig I just wear hats. Sometimes I forget that I don't have any hair and then I catch sight of myself in a window and go oh that's right I'm bald!
Anyway Julie you'll be fine and it will grow back not to long from now.
Take care Linda
