Many people have questioned whether the oily surface of the scalp is related to promoting hair loss. Referring to the recently published medical articles, we summarized whether oily scalp surfaces are related to promoting hair loss.


Seborrheic dermatitis is a skin condition with flaky, red, and dry skin due to overproduction of sebum by sebaceous glands. The condition itself does not cause hair loss, but it causes scratches or itching, and the yeast infection that usually follows does not help to maintain healthy hair. Seborrheic dermatitis may eventually be associated with some hair loss, but it is not a fundamental factor causing extreme hair loss.


Therefore, there are no direct findings yet on whether oily scalp surfaces are related to promoting hair loss. However, scalp diseases such as seborrheic dermatitis can be associated with hair loss, so proper shampoo and scalp care are needed to maintain scalp health.
