If you notice a greasy smell coming from your scalp when washing your hair at the end of the day, it is worth considering 'oxidized sebum.' Sebum is a natural protective barrier for the scalp, but its properties can change over time when exposed to air and ultraviolet rays. Director Jang Yoon-hee of Lydia 153 cites understanding this oxidized sebum as the starting point for scalp health management.

What is oxidized sebum?

Sebum contains a component called squalene. When squalene comes into contact with ultraviolet rays and oxygen in the air, it oxidizes and turns into squalene peroxide. If this oxidized sebum remains on the scalp for a long time, it can cause irritation or discomfort such as odor and itching. Therefore, rather than trying to eliminate sebum unconditionally, it is important to develop the habit of removing it promptly before it oxidizes.

4 Lifestyle Habits for Managing Oxidized Sebum

First is evening shampoo. Washing away sebum, dust, and impurities accumulated throughout the day before going to sleep allows your scalp to rest in a clean state overnight. Second, it is the water temperature. Water that is too hot can dry out the scalp, so it is best to wash with lukewarm water.

Third, thorough rinsing. If shampoo lather or residue remains on the scalp, it can mix with sebum and cause further irritation, so please allow ample time for rinsing compared to washing. Fourth, dry your scalp completely. If you fall asleep with wet hair, your scalp will remain damp for a long time, so it is recommended to dry your scalp before your hair using lukewarm air from a hairdryer.

Daily habits are the foundation of scalp health care

Scalp care begins with daily habits rather than something special. Understanding oxidized sebum and making slight changes to your shampooing time and method can help maintain scalp health. However, if symptoms such as itching, redness, or flaking persist for a long time, I recommend consulting a dermatologist rather than relying solely on self-care.
