Not only that, An An found some pimples on her scalp, and when she pulled them off hard, her fingernails would be stained with blood scabs, which looked scary.
Ann doesn't understand why her hair looks so "unhealthy" when she washes her hair every day.
Many people are troubled by dandruff, and some people have as much dandruff as it snows. But most people don't pay much attention to dandruff, thinking that it is enough to wash your hair frequently, but I don't know that dandruff may be an early warning of scalp aging.
Scalp is an extension of the skin of the face and neck, and its thickness is thinner than most of the skin of the face. Moreover, the scalp is rich in sebaceous glands, sebum secretion is relatively strong, hair follicle density is relatively large, and free radical accumulation is also relatively high.
In addition, the scalp is located at the highest part of the human skin, and the tension and gravity it bears are also relatively large. Therefore, the scalp is actually one of the most fragile and oldest parts of skin tissue.
Once the scalp is aged, the barrier function of the scalp will be damaged, and symptoms such as dryness, desquamation and excessive oil secretion will appear. Scalp will also become thin and loose, easy to itch and inflammation. At the same time, the hair will become thinner, the hair quality will become worse and grayer, and it will become sparse, prone to hair loss and even baldness.
Sometimes when we touch the scalp carefully, we can touch some small particles or acne. If you dig hard, there may be blood under your nails and your scalp is wet and painful. What's going on here?
If the particles you dig down are white or light yellow and very small, about the size of a small grain of rice, then this situation is relatively healthy. The main reason is that there is too much oil in the scalp, which is deposited in the sebaceous duct of hair follicle and cannot be discharged in time, thus forming a granular "white head".
But if the small particles you dig down belong to the following three situations, it is unhealthy.
1, folliculitis
The particles are relatively large, even like snowflakes.
Folliculitis is a kind of skin inflammation, which is mainly caused by bacteria (such as Staphylococcus aureus) infecting hair follicles. Scalp, face, neck, back and thigh root are all high-risk parts.
Folliculitis begins with a papule, which feels itchy and painful, and then the pus suppository falls off and purulent. Severe cases can cause fever, headache and other systemic symptoms. People with low immunity, such as the elderly, children, people in poor health and diabetic patients, are more likely to suffer from folliculitis.
To prevent folliculitis, first of all, we should do a good job of scalp care every day, wash our hair frequently, change the pillow towel frequently, don't scratch our heads when nothing happens, and try to avoid direct contact with chemicals such as tar. Eat less greasy and spicy food and eat more fresh fruits and vegetables.
If you are a patient with chronic diseases such as diabetes, you need to actively adjust your blood sugar. When scalp folliculitis's symptoms are serious, he should seek medical attention immediately.
2. Seborrheic dermatitis
The picked particles are small and chaff-like, or yellow and greasy.
Seborrheic dermatitis is a common chronic skin disease, which will appear in skin parts with a large number of sebaceous glands (scalp, face, etc.). ). Patients will feel itchy scalp, oily scalp and dandruff, erythema, papules and pustules will appear on the scalp. In severe cases, there will be yellow exudate on the scalp, and the symptoms will spread all over the body and even lead to hair loss.
People who lack sleep for a long time or often dye their hair are more likely to suffer from seborrheic dermatitis.
If it is seborrheic dermatitis, it is necessary to adjust the routine and diet, try to be low in fat and sugar, eat more fresh fruits and vegetables, properly supplement vitamin C, and keep enough sleep.
Step 3: psoriasis
These particles are thick and dry, white or grayish white, like fish scales.
Psoriasis, also known as psoriasis, is a chronic proliferative skin disease, and its occurrence is related to the interaction of genetic factors and environmental factors. On the scalp of patients with psoriasis, there will be red papules and plaques with clear boundaries, and silver scales will be covered, which are often distributed along the hairline, but generally will not cause hair loss.
If you find the symptoms of psoriasis, you should go to the hospital for examination and treatment as soon as possible. If you want to prevent psoriasis, you should avoid scalp irritation every day, take a bath for not too long, eat less or no spicy food in your diet, and keep your scalp warm.
Sometimes, the scalp also sends out some "distress signals", through which we can identify the health status of the body.
1, scalp numbness: cervical spondylosis
Cervical spondylosis can cause nerve and blood vessels to be compressed, and blood cannot be smoothly transported to the head, resulting in insufficient blood supply to the brain and numbness of the scalp.
2, scalp itching: fungal infection
Scalp itching and dandruff are mostly related to fungal infections, mainly "Malassezia".
Once it is a fungal infection, you must seek medical attention in time, and never blindly use dandruff shampoo to avoid aggravating symptoms.
The health of scalp is closely related to physical condition, so we should pay more attention to the maintenance of scalp. If you want to do scalp care well, you must first check whether your shampoo method is correct.
When washing your hair, you can't scratch your scalp with your nails. The correct way is to massage and circle the scalp with your fingertips. If you are worried about not being cleaned, you can comb your hair for a while before shampooing, and comb out the dust and dirt in your hair.
At the same time, the water temperature should be suitable when washing your hair, and about 40 degrees is better. Excessive temperature easily washes away more oil and nutrients from the scalp, and stimulates the scalp to secrete more oil, resulting in more serious oil production and dandruff. If the temperature is too low, it is easy to wash and cause headaches and colds.
In addition to washing your hair correctly, the hygiene of pillows is also very important for maintaining your scalp. When we sleep every day, our scalp will directly touch the pillow. Pillows are covered with saliva, grease, sweat and other substances, which are easy to breed mites and bacteria, cause skin problems and cause serious damage to the health of the head skin.
In addition to cleaning the pillowcase regularly, it is recommended to replace the pillow every 1-3 years and clean it every 3 months.
Oiling, desquamation, hair loss ... Many people have scalp problems. Scalp health is not only related to the healthy growth of hair, but also affects the aging speed of face, which is closely related to physical health. If you want to improve the scalp problem, you should not only wash your hair correctly and maintain your scalp, but also pay attention to conditioning your physique and improving your living habits.
