Everyone as covered all the gory bits so I'll go with a positive.
The best part about being bald is having a shower.
I too had very long hair, but didn't get it cut short. I just waited till it started to go then shaved. It wasn't as sad as I expected it to be, I guess I was prepared because I knew I had about 14 days from first treatment (after reading about it here). It happened day 13.
But jump under the shower and you'll know what I mean.
Good luck with it all, chemo is wrong on so many levels, just go with it, do as recommended and you'll make it through.
