Oily hair is caused by excessive sebum production by the seborrheic glands located in the scalp. The sebum is deposited only at the roots, creating a greasy appearance. Damaged or product-stripped hair is often dry and can also lead to overproduction of sebum. As a result, your hair will become greasy even more quickly in an attempt to combat this dryness. Our recipe of the day will therefore allow you to rebalance sebum production and detoxify the scalp.
