What is a common reason for hair to become oily?

A common reason for hair to become oily is excessive sebum production. Sebum is an oily substance produced by sebaceous glands in the scalp that helps to keep hair moisturized and protect it from damage. When sebaceous glands produce an overabundance of sebum, it can lead to hair appearing greasy or oily. This overproduction can be influenced by several factors, including hormonal changes, diet, stress, and genetic predisposition.

Understanding why excessive sebum production leads to oily hair is crucial for both clients and professionals in the beauty industry, as it illustrates the balance that needs to be maintained for healthy hair. Recognizing the role of sebum helps barbers advise clients on proper hair care routines and product choices that can mitigate the appearance of oiliness without stripping the scalp of necessary moisture.
