The scalp is more fragile and prone to aging than the face

“The scalp is greasy and itchy, dandruff increases; hair is dry and split, and hair loss is severe… When these problems occur, it may be the scalp that is sending an early warning.” Dr. Liu Jie, deputy director and chief physician of the Department of Dermatology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, said in the interview Said in an interview with a reporter from Science and Technology Daily.

In order to raise people’s awareness of scalp health, the Swiss HICAS Biological Research Center designated November 1 of each year as “World Scalp Health Day” in August 2012. What are the factors that cause an unhealthy scalp? How to tell if your scalp is healthy? How to care for your scalp in daily life?

The scalp is the key “soil” for healthy hair growth

The scalp is an important and special part of the skin and is the key “soil” for healthy hair growth. If you don’t pay attention to care, it will often cause a variety of scalp and hair diseases.

Liu Jie said: “The scalp is more fragile and prone to aging than the skin on the face. Once problems occur, the hair may become dry and frizzy, and the number of hair loss may even increase significantly.”

Liu Jie said that common scalp diseases include seborrheic dermatitis, psoriasis and folliculitis. Different common scalp diseases have different manifestations and causes.

For example, seborrheic dermatitis, one of the most common scalp diseases, often presents with scalp redness, greasiness, increased dandruff, and itching. The occurrence of this disease may be related to Malassezia, increased secretion of scalp oil and changes in its composition.

Many people don’t know that the scalp is also a common site for psoriasis (commonly known as “psoriasis”). Its occurrence is related to family inheritance, immune response, infection and mental stress. When patches of erythema, itching, and a lot of dandruff appear on the scalp, especially at the hairline, and even hair becomes bundled, you need to be highly vigilant.

Teenagers are prone to scalp folliculitis, which often appears together with facial “acne” (acne), manifesting as red papules and pustules, accompanied by pain. In severe cases, nodules or cysts can be formed. If not treated promptly, it may leave scars and even prevent hair from growing back. This disease is related to increased scalp seborrhea and Staphylococcus aureus infection.

Use scientific methods to care for your scalp

How should we deal with common scalp diseases? Liu Jie said: “Take the most common seborrheic dermatitis as an example. For patients with mild symptoms, they first need to adjust their living habits, including maintaining a relaxed mind, regular work and rest, eating less greasy and spicy food, and avoiding irritation from tobacco and alcohol. , less perming and dyeing, etc. The above adjustment of living habits is beneficial to most scalp diseases. Good living habits are the cornerstone of scalp health.”

At the same time, when maintaining your scalp on a daily basis, you should use scientific methods to “detoxify” your scalp: reduce the use of overheated water and alkaline soap to wash your hair; for those with greasy scalps and a lot of dandruff, it is recommended not to wash your hair frequently and wash your hair every day. Do not wash your hair more than once; for those with dry scalp and dry hair, it is recommended to wash your hair every other day. In addition, the frequency of hair washing can also be adjusted according to the season. When there is excessive sweating in summer, the frequency can be increased appropriately, and when it is dry in winter, the frequency can be appropriately reduced.

Liu Jie said that if the control effect of these measures is not good, you need to go to the dermatology department of the hospital in time to determine the diagnosis and treatment plan. For seborrheic dermatitis with red scalp, excessive dandruff and obvious itching, you can use external selenium disulfide or ketoconazole lotion. In severe cases, you can also use compound preparations containing hormones, combined with oral vitamin B complex (containing B2, B6) Treatment. If folliculitis also occurs on the scalp, antibiotics such as fusidic acid cream and mupirocin ointment can be applied locally for treatment. In severe cases, antibiotics or isotretinoin can be taken orally under the guidance of a doctor. For scalp psoriasis, tar-containing shampoo, selenium disulfide lotion, calcipotriol liniment, salicylic acid preparations and glucocorticoid preparations can be appropriately used for treatment.
