My boyfriend's neice swares by nads, but she doesn't have PCOS. She has used it to wax my toes and the top of my feet, and it did a pretty good job.
She also waxed my lip too. But I don't have a lot of hair there. I can't wax my chin, because the hair is too coarse.
And, we make a night of it...a beauty night, waxing, plucking, moisturizing, soaking. Quite a bit of fun, since I never had a sister.
So, IMO NAD's is good for thin hair.
