Dry The Scalp First
When you're drying your hair with a hairdryer, your first thought should always be to make sure to get the scalp dry first. If you focus on the scalp and roots you’ll get the whole head of hair dried a lot quicker then you can start to really focus on styling the hair and setting it into the desired shape.
If you dry and style the hair into position with the scalp not fully dry, you’ll find that the moisture still on the scalp will then add moisture back into the hair which will in effect set it back to its original state. It will end up falling really quickly, not maintaining the desired shape and end up being completely unruly. Think of it like a humid day how that changes the shape of your hair really quickly!
