Hair oil is mostly caused by damp heat, or it damages the spleen and stomach, turns damp into heat, fumigates the skin and forces excessive secretion of oil. Some people are phlegm-damp, while others are caused by acquired bad living habits. For example, people who love sweets and fish are prone to phlegm. When phlegm-dampness is endogenous, the body's fat metabolism is not smooth, and the nutrients that cannot be digested and excreted become waste, which is blocked in the body, causing damp heat and unable to be discharged, thus accumulating fumigation in the scalp. After a long time, greasy hair will appear.

Modern people like high-calorie and high-fat food. Eating greasy and spicy food will stimulate the secretion of sebaceous glands. Staying up late, playing computer for a long time, fast-paced life and high-intensity work pressure will all affect the endocrine system of the human body and aggravate scalp oil.

After washing your hair frequently to remove the grease from the scalp, sebum will receive the message of "lack of oil", and then further secrete oil, resulting in more and more secretion and more oily hair.

What if the hair is always oily?

Rinse with clean water every once in a while to control grease.

If you are used to washing your hair every day, or don't wash it, you will secrete too much oil. Even if you wash your hair every day, you don't need shampoo and conditioner. You can rinse it with clean water every other day, and you can also remove stains on your hair and scalp without increasing oil secretion. For people who are not oily, washing their hair two or three times a week is enough.

Don't dry-clean your hair and massage less to stimulate your scalp.

Many people like to go to the barber shop to dry-clean their hair, that is, directly pour shampoo on their dry hair and rub it for 10 minutes or more. In fact, wiping the scalp with oily hair will only promote the exuberance of oil secretion, and the shampoo in the barber shop is not very reliable. It is recommended to wash it quickly and wet.

Do less healthy combing.

Although massaging the scalp with fingertips in the morning and evening has a certain health care function, for the scalp that is easy to get oil, it will passively disperse the oil to the hair shaft, stimulate oil secretion and aggravate oil production.

Change shampoo

People with oily hair had better use shampoos containing zinc pyrithione or salicylic acid. Most of these substances exist in dandruff shampoo, which can help control scalp oil.

Hair is often cut

The longer the hair is, the more it will sag under the action of gravity, and the greater the tension on the hair roots, so it is easier to get oil and looks flatter. People are advised to trim their hair at least once a month, which can not only help control oil, but also protect hair roots.
