The formation of the scalp, how the scalp is produced

Scalps that are too dry or too oily can cause dandruff. I'm using Zele. It is sold in pharmacies or supermarkets. It has an effect after 2 times. Pretty good. You can try.

1. Dandruff produces a lot of oil, and the important cause of dandruff is a parasitism of Malassezia. This is a normal parasite on the human body, which feeds on sebum, and excessive proliferation can lead to dandruff, so people with a lot of oily scalp are more likely to have dandruff.

2. Lack of sleep, sufficient sleep can promote normal metabolism, try to avoid staying up late, it is best to go to bed before 11 o'clock at night.

3. Spicy diet, excessive smoking and alcohol, spicy diet, excessive smoking and alcohol will affect the absorption of nutrients, and harmful substances will affect the body's metabolism after absorption. Therefore, eat more vegetables and fruits, and eat less greasy and sugary foods.

4. When the body is unwell, it is also easy to have an increase in dandruff, such as gastrointestinal dysfunction, nutritional imbalance, endocrine disorders, etc., which often lead to changes in the body's hormone levels.

5. Over-cleaning, some people think that dandruff is due to lack of hygiene, so it is wrong to over-shampoo. Overshampooing can lead to dry, dehydrated hair, which can worsen dandruff.

The scalp refers to the ** tissue located in the head, and its main function is to protect the tissues and organs of the head, and it also has the functions of regulating body temperature and feeling touch. So, how is the scalp formed? How does it work? Let's break them down one by one.

In addition to this, the scalp also has certain metabolic functions. The sebaceous and sweat glands of the scalp secrete sebum and sweat, and through these secretions, excess water and waste products can be excreted from the body. The scalp can also secrete a substance called "hair growth factor", which promotes hair growth and development.

In short, the scalp is an important part of the human body, and its formation and function are of great significance to the physiology and health of the human body. We should protect our scalp and keep it healthy and clean, so as to better play the function of the scalp.

In addition, the scalp also has a certain metabolic function. The sebaceous and sweat glands of the scalp secrete sebum and sweat, which allow excess water and waste to be excreted from the body. The scalp can also secrete a substance called "hair growth factor", which promotes hair growth and development.

The scalp is a soft tissue at the top of the skull, which is divided into five layers: superficial fascia, superficial fascia, cap aponeurosis and muscle, subaponeurosis loose connective tissue and periosteum.

** Thick and dense, rich in hair follicles, sebaceous glands and sweat glands, it is the area that is prone to boils. **The blood supply is abundant, and there is a lot of bleeding after the injury, but the healing power is strong.

There are fiber bundles inside, which are attached to the cap-shaped aponeurosis. When the scalp is torn, it is often all three layers involved together. The subcutaneous tissue is divided into lobules by fibrous bundles, and the neurovascularity runs within the lobules.

The blood vessels distributed on both sides are from back to front, including occipital blood comic ducts, postauricular blood vessels, superficial temporal vessels, supraorbital vessels, and supratrochlear vessels; The nerves on each side are the greater occipital nerve, the lesser occipital nerve, the posterior auricular nerve, the auricular temporal nerve, the supraorbital nerve, and the supratrochlear nerve from posterior to anterior. They travel from the periphery to the top of the head, so the flap is often turned downwards during the actual craniotomy. The nerve distribution of the scalp overlaps each other, and the blood vessels anastomoses with each other.

Therefore, the scalp is amenable to block anesthesia. The blood vessels run in the lobules, and the wall of the tube is tightly adhered to the fiber bundles, so there is more bleeding after injury, and the hemostasis should be compressed around the wound.

Very dense, aponeurosis between the occipital and frontalis muscles, which connects anteriorly to the frontalis muscle and fuses with the orbicularis oculi muscle; Attach the occipital muscle posteriorly and terminate at the superior neckline. The two sides are fused with the temporal fascia of the Shanhu tribe and attached to the upper temporal line. When the scalp injury does not involve the gauntlet aponeurosis, it does not dehiscence.

It is also known as loose connective tissue space, which originates anteriorly from the root of the nose and the margin of the eyelid; After reaching the upper neckline; Both sides to the temporal line. In subaponeurosis hematomas or abscesses, they tend to spread to the entire cranial roof. **In addition to the peripheral veins, the veins also pass through the conductive blood vessels in the subaponeurosis space and flow into the intracranial venous sinuses, and the infection in the space may spread to the skull.
