Xiaomei's mother is worried that this will affect the health of her hair or head and cause more serious diseases. Why does the scalp grow acne and pustules?
Compared with "face", scalp care is often neglected, but it should be paid more attention to.
There are a lot of sebaceous glands, sweat glands and hair follicles on the scalp, more than on the face. There are about 144- 192 sebaceous glands per square meter, and there are about 42-78 sebaceous glands on the face.
Sebaceous glands are used to secrete oil. Proper amount of oil can protect and moisturize the skin and prevent dryness. Once secreted too much, it is easy to block pores, sebaceous glands can eliminate obstacles, and hair follicles can't be ruled out. There are many bacteria and microorganisms in hair follicles, which cause skin redness and swelling in the process of killing bacteria and microorganisms by white blood cells.
In addition, the metabolism of the scalp is faster than that of the skin. In addition, dense hair is easy to leave particles and pollutants in the air, which will further harm the scalp and make it age faster, leading to dry hair, yellowing, bifurcation, easy breaking and falling off, thus causing a series of scalp hair health problems.
There are four common causes of scalp acne and pustules.
1. folliculitis
When the hair follicle is infected by staphylococcus and other pathogenic bacteria, it will cause folliculitis, resulting in unbearable itching. I can't help scratching with my hands when I itch, which further aggravates the infection.
In addition, I often stay up late, overworked, and nervous. , will reduce immunity, or excessive secretion of sebaceous glands will block hair follicles, but also cause folliculitis, manifested as papules and pustules on the scalp.
2. Seborrheic dermatitis
Seborrheic dermatitis is mainly related to the metabolic disorder of human body, which is characterized by white patches on the scalp, more dandruff, obvious itching, redness of the scalp, and sometimes oozing and scabbing.
3. Scalp rash or eczema
Scalp rash or eczema is an inflammatory skin disease caused by immune system dysfunction, which is characterized by dry flaky patches on the scalp, accompanied by burning and itching.
4. Scalp squamous cell carcinoma
Scalp squamous cell carcinoma is a kind of skin squamous cell carcinoma, which is mainly related to frequent ultraviolet radiation, long-term exposure to carcinogenic chemicals, chronic skin diseases, immune system dysfunction and other factors. Scalp squamous cell carcinoma presents as flaky erythema with desquamation and scab, with rough surface and hard texture.
For treatment, Ding Lei, deputy chief physician of dermatology department of Qingdao Third People's Hospital, suggested that some ointment containing anti-inflammatory antibiotics could be selected. In severe cases, we should go to the outpatient department of the hospital for examination and test, and carry out symptomatic drug treatment.
If it is high in oil and metabolism, it is recommended to use a little sulfur soap to change the habit of washing your hair. At the same time, improve living habits. In autumn and winter, the diet is mainly light and warm.
Many people have scalp problems, such as dandruff, easy to get oil, erythema of unknown cause, and itchy scalp. Scalp health is very important How do you know if your scalp is healthy? Yang Dingquan, director of the Hair Medicine Center of China-Japan Hospital, introduced three standards.
Normal oil production: the oil on the scalp is actually secreted oil. Generally speaking, the scalp secretes more oil in summer than in winter. If you don't wash your hair for one day in summer and two or three days in winter, your hair will become oily, which may be caused by excessive oil secretion.
Too frequent or too few times of shampooing will cause excessive oil secretion. It is suggested to adjust the frequency of shampooing, and it can be adjusted to 2~3 times a week for people with neutral or dry hair. For oily hair, if you don't wash it, you will secrete too much oil, so you can only rinse it with water as appropriate.
Scaleless: The normal renewal cycle of scalp cells is 28 days, and more than 90% people will produce physiological dandruff, which is a normal metabolic phenomenon of the body.
However, if there are a lot of scales on the scalp, it will be brushed off as soon as the hair is combed, and it is extremely itchy, which will attract attention, indicating that the scalp may have health problems.
No inflammation and erythema: If the scalp oil secretion is excessive, Malassezia on the scalp will over-multiply, constantly stimulate the scalp, cause scalp inflammation, grow erythema, and be accompanied by itching symptoms.
If this happens, it is recommended to go to the hospital dermatology department to find out the reasons and deal with the symptoms. In the choice of shampoo, try dandruff shampoo. The zinc pyrithione and pyroketoethanolamine contained in it can inhibit the growth of Malassezia.
If you don't pay attention to scalp care, it may accelerate aging and even cause problems such as hair loss, rash and dermatitis. If you want to delay scalp aging and have a healthy scalp, try to avoid these five things.
1. Hair dye and conditioner contact the scalp.
When using hair dye, protective measures should be taken to avoid direct contact with the scalp, so as to avoid harmful chemicals from penetrating into capillaries through the scalp and causing potential health risks. When applying conditioner, try to avoid touching the scalp. Apply it at a distance of/~ 2 cm from the hair root/kloc-0, and keep it for about 5 minutes.
2. Wash your hair with your nails.
It's easy to hide bacteria under your nails. When washing your hair, the intensity should be appropriate. Don't scratch with your nails to avoid damaging your scalp and being invaded by bacteria and viruses. And scratching your scalp with your fingers will only get itchy. The correct method should be to gently massage the scalp with your fingertips.
3. Water impact spinning
Some people like to turn on the tap when they wash their hair. In fact, hair curl is the core area connecting hair and scalp. It is easy to damage the scalp by the impact of violent water flow, causing serious hair loss. When washing your hair, turn down the water, don't rush directly at the hair spinning place, and don't wash it for too long.
4. The shampoo is too hot
Our scalp is very fragile. Washing your hair with too hot water will destroy the skin barrier of the scalp and damage hair follicles and hair quality. Second, it will cause the loss of moisture and oil on the scalp surface, resulting in dry scalp and easy dandruff. It is recommended to use warm water of about 40 degrees Celsius.
5, cleaning is not clean
You can't just scratch your hair twice. You should clean every corner carefully and wash away the dust and particles left on your hair and scalp. In addition, after applying shampoo and conditioner, rinse thoroughly, otherwise it will easily clog pores and cause hair loss.
In our daily life, we must take good care of our scalp. Wash your hair scientifically, change bad habits and make your scalp healthier.
