In addition to the visible parts, there are invisible parts, which are divided into complex components such as epidermis, dermis and subcutaneous tissue, and also contain rich skin and sweat glands.
When our scalp is unhealthy, it will cause a series of problems.
So, what should a healthy scalp look like? In fact, everyone has four criteria to judge whether their scalp is healthy or not.
0 1 scalp is relaxed and not tight
Modern people have great pressure in life, nervous, and the scalp is easy to be in a tight state. Scalp tightness generally comes from mental fatigue, lack of sleep, or emotional tension. In short, scalp tension mostly comes from mental stress. As long as the scalp is not tight, pressing the scalp is not particularly sensitive to stimulation, indicating that the scalp is still healthy.
No obvious dandruff can be seen with the naked eye.
Dandruff is the normal metabolic product of the scalp, the secretion product of keratinocytes shed from the scalp, and contains certain oil. Under normal circumstances, oil can't be seen clearly, but under some stimulation, immature keratinocytes will be produced in large quantities, agglomerate and fall off, forming what we often call dandruff. Therefore, as long as you wash your hair normally for 1-2 days, you can't see dandruff, which is basically normal.
There is no itching sensation on the scalp
Scalp itching is also related to dandruff. Scalp itching is caused by the destruction of scalp flora. If left untreated, it will cause imbalance of oil and metabolism, leaving the whole scalp in a state of disorder. Under normal circumstances, the scalp is normal and there is no special itching.
Keep the scalp fresh.
Many friends will complain that I get greasy just after washing my hair. This is the most typical scalp oily. Only a scalp that can be kept fresh at ordinary times is a healthy scalp.
The above four criteria are the state of a healthy scalp. What problems can unhealthy scalp cause and how to solve them?
1, scalp oil secretion.
Some people's scalp oil glands are exuberant, and oily substances are distributed all over the hair roots and the whole scalp.
Even if it has just been cleaned, the scalp will become very greasy at the end of the day, and even clog pores and breed bacteria.
In this case, we must first judge what is wrong with the scalp. If the scalp is a little red, folliculitis quickly develops into pustules. If only the scalp is oily and shiny, it is seborrhea.
Suggestion: Get enough sleep, eat less greasy and spicy food and eat more fruits and vegetables. You can use sulfur soap to wash your hair, or use salicylic acid ointment and other drugs according to your doctor's advice, or use ketoconazole lotion to clean your hair.
2, scalp itching, dandruff
As mentioned earlier, the scalp is itchy and can't help scratching, accompanied by a lot of dandruff. It's actually caused by fungi. If you scratch blindly, it will only further damage the scalp and let a lot of dandruff fall.
For scalp itching, in addition to cleaning hair with ketoconazole shampoo, you should also eat less spicy and greasy food and avoid alcohol and tobacco, because irritating food will aggravate itching. In addition, it is also important to keep the scalp clean, and try to clean it once every 1-2 days.
3, hair loss
Excessive scalp oil overflow is often accompanied by excessive dandruff and greasy scalp, and finally there will be regular hair loss on the top of the head or forehead, which is what we often call seborrheic hair loss.
Suggestion: Quit smoking and drinking to relieve mental stress. The daily diet should be as light as possible, ensure adequate sleep, massage the scalp properly, and ensure sufficient blood supply and oxygen supply to the scalp. At the same time, we should actively cooperate with the treatment. At present, in addition to minoxidil and finasteride, hair transplantation can also be used to change the state of hair loss.
