Oily hair loss, also known as seborrheic alopecia, is generally recommended to wash hair 2-3 times a week. Seborrheic alopecia is mainly due to excessive secretion of sebum from the scalp and certain chemical composition changes, resulting in the proliferation of normal flora present on the skin, which further invades the skin follicles and leads to hair loss, and in severe cases, hair loss can occur. It is usually recommended to wash your hair 2-3 times a week and choose a shampoo with oil control properties, together with the use of drugs that reduce oil secretion, which can effectively inhibit hair loss. In addition, patients with oily hair loss need to be careful not to wash their hair too often to avoid disrupting the normal oil balance of the scalp and aggravating the hair loss situation. Patients with oily alopecia should ensure a regular life in daily life, maintain an optimistic attitude and avoid excessive mental stress. You can properly eat more vegetables and fruits to supplement vitamins.
