If you think conditioner causes oily hair, you’re wrong. “Greasy hair is caused by a problematic scalp,” not by certain products, says Umberto Savone, creator of the Umberto Beverly Hills hair care line. The only cure for greasy hair is to cleanse the oil and buildup that clogs the pores of the scalp.

To do this, use a stimulating and exfoliating oil to remove build up (since oil attracts oil). Try using jojoba oil, says Ona Spa therapist Angelica Sepulveda, as it most closely matches your natural hair oils. Then shampoo with an exfoliating shampoo and lightly condition, says Savone.
