early baldness
Introduction
Introduction to early baldness Early alopecia prematura is also called male pattern alopecia, familial baldness, seborrheic alopecia, hereditary alopecia, and androgenetic alopecia. Early baldness means that before the old age, the hair gradually falls off prematurely during the young adulthood. Often, the hair is peeled back from the front edge, or the hair at the top of the head is thin until the hair of the entire scalp is removed. Hair loss is often progressive, family-oriented, and more common in men. basic knowledge The proportion of illness: 0.003% Susceptible people: more common in men Mode of infection: non-infectious Complications: social phobia
Cause
Early alopecia
Genetic factors (30%):
The cause of premature alopecia is unclear, but patients often have a clear family history. The earliest detectable change is the degeneration of the lower part of the hair follicle in the connective tissue of the hair follicle, accompanied by changes in basophilic tropism. The hair follicles gradually shrink and become smaller, and are finally replaced by bristles. Finally, many bristles and hair follicles disappear, and the hair follicles gradually leave a bundle of hardened glass fiber-like connective tissue.
Androgen is too high (25%):
A sufficient amount of androgen in the blood is often an important factor in the development of early baldness. Males do not develop early baldness before puberty, but long-term treatment with testosterone can occur early baldness, early baldness increases with age, the baldness, pubic hair and mane of early baldness do not fall off, and the initial involvement of hair follicles is 5-a- Dihydrotestosterone builds up, which may inhibit hair follicle metabolism.
Other factors (20%):
This disease is often accompanied by seborrhea, but it has been confirmed to have no causal relationship with early baldness. In addition, local factors such as too tight a hat, wearing a cap at night, and shampooing with a cold (or overheating) are not major factors.
Prevention

Men's hair loss mainly occurs in the top of the forehead, and the anterior margin of the hair, especially on both sides of the forehead, retreats, so the forehead becomes higher, especially at the two horns, extending upwards and backwards. As the condition worsens, the top of the head is bare. Only the remaining hairs are retained on the occiput and on both sides of the ankle. The scalp at the hair loss is smooth, and the slender bristles are visible, with no symptoms or only slight itching. Different patients have different forms of hair loss and hair loss, but most of them have a slow course of disease, which may be accompanied by seborrheic dermatitis or seborrhea. Some patients with mild disease only have hair loss at the two corners and sparse hair at the top of the head.
Women's hair loss is rare, and the degree is also light. Generally, diffuse hair is detached. It is obvious at the top of the head and gradually falls off, but it is not detached. The two horns are rarely hair loss. The hair is soft and tarnished. The scalp of the affected area is thin and can have a burning sensation. Itching or pain, it is difficult to grow new hair in the future.
Examine
Early bald examination
1, the detection of the body's immune function. (including the determination of interleukin 2 and its receptor levels, T lymphocyte and its subpopulation assay, NK cell level determination, etc.).
2, trace elements.
3, endocrine detection (thyroid, adrenal gland, detection of pituitary secretion function).
4. Pathological section of the scalp.
5, head treatment skin microcirculation test.
6. Is there too much androgen?
7, cervical spine deviation (Orthopedics).
Diagnosis
Diagnosis of early baldness
diagnosis
According to family history, alopecia and other clinical manifestations, the diagnosis is not difficult, women with diffuse alopecia must be excluded for other reasons, such as postpartum alopecia, or with other systemic diseases such as typhoid, anemia and so on.
The earliest detectable change was the degeneration of the lower part of the hair follicle in the connective tissue of the hair follicle, accompanied by changes in the basophilic vascularity. The hair follicle gradually atrophied and became smaller and finally replaced by the bristles. Finally, many bristles, hair follicles disappeared, and the hair follicle gradually disappeared. Leaves a bundle of hardened fiberglass-like connective tissue, and the hair follicle growth period in the final hair loss area is shortened. The percentage of hair follicles in the rest period is increased, the hair is loose and easy to fall, the epidermis is thin, the epidermis is flat, and the subepidermal capillary plexus almost disappears. The deposition of sulfur-containing mucopolysaccharides is increased, and the activity of the hair follicle enzyme is generally normal.
