I am so glad you posted this question/pic, because when I had Addy's hair in pigtails (you can look in the album if you didn't see it already -- Addy is in the last several pics.Addy in pigtails

My Addy's hair looked JUST like yours. She also is a first edition (with the numbers on her head). But look at those pigtails, she has a LOT of hair!

We don't have much trouble with breakage, and I can still play with her hair a lot. I hadn't even thought of replacing it, but I did wonder if it was "normal."

If her hair is back in one pigtail, or braided, you don't see any bald spots at all. She had a lot of hair.
