Yeah that was not a good advert for that brush, personally I think hair extensions with short hair like hers only look good when curled as it hides the join so much better. The brush just looks like too much work for very little benefit and still really frizzyHer extensions in that video look shocking. I get it’s hard to blend short hair with long extensions but they look so bad. Does not make me wanna buy that brush. It all looks absolutely fried.
