She explained: "If you're brushing your hair with that hairbrush it's going to transfer that all to your scalp and give you that greasy look."
As a rule of thumb, she revealed you should wash your hairbrush at least once a week.
The second reason your hair may be getting greasy quicker than it should is because you are wearing it up at night.
The skincare expert said: "This concentrates all of the oil directly into the scalp, oil has nowhere to go, it can't go anywhere else, it's stuck in your scalp and you wake up with a greasy head."
