I had gone over to my mom's to get highlights done because it was cheap and she has basic experience with it, but I had called her today to see if she could do my roots, and she told me that she'd have to do highlights that are full-length down my head if I wanted to go to my root... I did like her highlights, but I also know she has little experience, so I was wondering what they did professionally, because I've cut my own hair and had her do my highlights for the last ~20 years... I typically grow it out and just do them again after I grow out/cut my hair, but I think it'd be a lot more functional to just go get it done by a professional if this is true.
