Another thing... are you using little latex bands like they have at the orthodontist office to put her hair back? If not, you should try them bc that helps they stay in and not to break the hair and also make sure when you take her topknot out that you just cut it bc you will break the hair by trying to pull the band out of it and this will just make it seem to take longer for her bangs to grow bc you may be breaking the hair.
Most of the time I just put a colored band in he hair bc the bows come out too easily bc her hair is too short, but with the colors, it still looks cute! You can get colored bands here:
