Oily hair is caused by the excessive production of sebum in the scalp by the individual sebaceous glands at the roots of the hair. It’s necessary to include a purifying ritual, using shampoos for oily hair and complementary care that allow a deep cleansing to rebalance the hair and scalp. These products control oil excess for looser, lighter, and beautiful hair. Ducray Sabal Shampoo for oily hair and Vichy Dercos Shampoo Sebo Corretor, are products that effectively eliminate greasy hair.
