Hoe does Ariana Grande change her hair color so often?

Like one day she will have it light brown, almost blonde, then the next she will have it dark brown. I know she is not dying it anymore because she doesnt want to damage her hair again (and who would dye their hair every other day anyway), I dont see how it could be extensions because when she has it dark, it is all dark, its not highlights. And i know shes not wearing a full on wig either. Im just wondering how she is able to go from light to dark so often?

if it's her real hair. She's pretty much damaged her hair. It's not healthy to dye your hair so much
Or it could be wigs
