My Fiona seems to loose a lot of hair. I up her hair up and cut the bands but she still has a few small bald spots.

She also seems to shed a little. She has since I got her and it seems to not be slowing down. Her hair is so thin now. I thought it was puppy hair at first but she is 7.5 months old and still shedding a little. Any suggestions?
I was also wondering if anyone would share the secert to finishing off the end of ribbon bows so they don't frey. I am making her one for Thanksgiving and the method I am using doesn't work very well. Anyone care to share?
As always thanks for the help!
