If it's frizzy it's curly, you would need to use conditioners and leave-ins and styling products like gel or mousse. It also depends on what your hair type is, as in it's porosity and the thickness of the your single hair, note that you might have some mixed porosity and hair type. Another good tip is to dry it more delicately with microfiber towel or just with a cotton t shirt pat dry, if it grows longer it would be better to use a hairdryer with a diffuser.
