What are the reasons for oily scalp? Do you know these reasons?

Most young people have oily scalp, which is closely related to their normal diet and daily routine. Some people also have oily scalp because they wash their hair too frequently or try to use shampoo containing silicone oil.

1. Greasy, spicy food, irregular work and rest

Modern people like high-calorie, high-fat foods, and eat greasy and spicy foods, which will stimulate the secretion of sebaceous glands. Staying up late, playing computer games for long periods of time, living a fast-paced life, and high-intensity work pressure will all affect the body's endocrine system and aggravate oily scalp.

2. Washing your hair too often

Regardless of whether the hair is clean or not, it has become a habit for many urban white-collar workers to wash their hair once when they get home at night and again when they go out in the morning. In fact, not washing your hair for a long time will cause it to become oily, and washing your hair too frequently will also cause it to become oily. Because sebum is secreted based on information feedback. After washing your hair frequently to wash away the oil on your scalp, the sebum will receive the message of "lack of oil" and then further secrete oil, which will lead to more and more secretion and oilier hair.

3. Excessive use of chemical hair products

Before using hairspray or styling spray to style your hair, if your hair is already too oily, isolating your hair from air for a long time will make your scalp even more oily.

4. Silicone oil in shampoo

Silicone oil is a compound called polydimethylsiloxane. It is viscous when liquid and is insoluble in water but soluble in oil. Polydimethylsiloxane, a transparent substance, has excellent physical properties. When it is added to shampoo, the hair will be so smooth that even the comb cannot get stuck.

Although shampoos containing silicone oil do not harm the human body, long-term use of the same silicone-containing product can lead to hair loss and oily hair.
