Does having overly oily hair cause hair loss?

Excessive oiliness of the hair can indeed potentially lead to hair loss. Oily hair is usually caused by excessive sebum production from the scalp, which may be related to individual endocrine factors, dietary habits, lifestyle, or genetic factors. When the scalp produces too much oil, it can easily clog hair follicles, affecting the follicles' normal respiration and the hair's nutrient supply, thereby causing the hair to become thin, weak, prone to breakage, and even to fall out. In addition, an oily scalp environment can promote bacterial growth, leading to scalp inflammation and further aggravating hair loss. Therefore, overly oily hair may increase the risk of hair loss. To improve this issue, it is recommended to keep the scalp clean, shampoo regularly, use shampoo suitable for one's hair type, avoid consuming excessive greasy foods, and maintain healthy lifestyle habits and a positive mood. If hair loss is severe, it is advisable to seek timely medical attention from a professional doctor.
