Hair consists of hair shaft, hair root and hair follicle, there are about 100,000 hair follicles in the scalp, no new hair follicles can be added in adulthood, a hair goes through anagen phase (90%, 2-6 years), regression phase (1%, 2-3 weeks), resting phase (8%, 2-3 months), life span is about 2-6 years, adult hair can grow about 1CM per month on average.
Is hair loss a disease and do I need to see a doctor?

What are the common hair loss disorders?
There are many factors that cause hair loss, including genetics, mental and emotional, nutritional deficiencies, endocrine disorders, autoimmune diseases, medications, infections, inflammatory skin diseases, etc. The condition and prognosis of hair loss varies from cause to cause.
Alopecia areata is often divided into scarring alopecia and non-scarring alopecia. Scarring alopecia permanently destroys hair follicles and leads to permanent hair loss. Common causes include trauma, burns or scalds, infections (balding folliculitis, etc.), and inflammatory skin diseases (e.g., discoid lupus erythematosus, lichen planus, etc.). Non-scarring alopecia can grow back after the causative factors are removed.
The following are common types of non-scarring alopecia: androgenetic alopecia, baldness, resting alopecia, anagen alopecia, pulling alopecia, and plucking alopecia.
What is Alopecia areata?
It is an autoimmune alopecia areata disorder. In fact, any part of the hair can be affected and hair loss can occur. The triggers for the occurrence of autoimmune disorders are complex, some are related to mental emotions, and sometimes high fever, surgery, body blows, vaccinations, other endocrine or autoimmune diseases may trigger baldness, but some people cannot find any triggering factors. Treatment is based on removing the triggers and regulating immunity. Most cases of baldness are mild, involving only part of the scalp, and can heal on their own within 6 months to 2 years. However, some patients have more severe cases, involving most of the scalp and eyebrows, eyelashes, pubic hair, axillary hair, and even sweat hair and nails, and are less likely to heal on their own.
What is resting hair loss?
In fact, resting hair loss is the most common type of hair loss in daily life, but it is not noticed because most of the hair loss is mild. There are many reasons for its triggering, including physiological ones such as newborn hair loss and postpartum hair loss, which can recover naturally. Pathological factors include mental and emotional factors, nutritional deficiencies, endocrine diseases, poisoning, drugs, infections, etc. It can be recovered after the trigger is removed. Nowadays, many people have irregular life, often stay up late, overeat, and sometimes skip meals, all of which may lead to resting hair loss.
What is Telogen Effluvium?
Commonly seen in women with ponytails, chronic long-term pulling of hair can cause the pulled hair to fall out, and in severe cases, can lead to permanent loss.
What is hair pulling alopecia?
It is a psychological disorder that often involves anxiety and occurs in children as well as adults. Patients often pull their hair, eyebrows, beard and even eyelashes unconsciously without feeling pain. It is characterized by a relatively long white film at the root of the lost hair, and can stick to books, tables or walls, where normal, non-shedding hairs can be seen in the area of hair loss.
Do not believe in advertisements and prescriptions
Due to “hair saving”, some patients believe in advertisements and prescriptions and try various shampoos, kidney supplements and “special prescriptions” that claim to have “anti-hair loss” function, expecting These means without scientific basis can not solve the hair loss problem at all, but delay the treatment opportunity, should go to the regular medical institutions for correct diagnosis and adhere to the regular treatment.
Does the treatment of hair loss require the avoidance of food
There is no evidence to show what kind of food can cause hair loss. However, some studies have reported that high levels of lipids can increase the amount of free testosterone in the blood, which may aggravate androgenic baldness, so it is important to pay attention to the rationalization of your diet, both for the sake of your hair and for the overall health of your body.
Does eating more foods like black sesame and walnuts help to treat hair loss?
The growth of hair requires balanced nutrition. Foods like black sesame and walnuts can supplement some trace elements, vitamins, and non-saturated fatty acids, but they cannot meet all nutritional needs, so proper intake is desirable, but it does not serve the purpose of treating hair loss.
Can improper hair washing cause hair loss?
There is no evidence that washing your hair and shampooing can affect hair growth. If hair is not properly shampooed the most direct damage is to the scalp and hair shaft (hair strands), which may result in dandruff, itchy scalp, dry and brittle hair, etc.
Can conditioner cause hair loss?
The main function of conditioner is to fill the defect of damaged hair microdermis (hair scales) on the surface of hair shaft (hair strands) and neutralize the negative charge on the surface of hair shaft, so that the friction on the surface of hair shaft is greatly reduced and hair becomes smooth. During the shampooing process, many hairs in the resting phase fall out due to external forces. Since the conditioner reduces the friction between the hairs, it makes it easier for these hairs that have been shed out of the hair follicle to fall out in a concentrated manner, so it just appears that more hair is shed at this time, rather than causing hair loss.
For patients with long hair loss, especially for dyed and permed long hair, proper use of conditioner is necessary to reduce the number of hairs that fall out and break off due to stretching during combing.
Can I apply ginger juice topically to regrow my hair?
There are many types of hair loss with different causes and complex pathogenesis, and there is no specific medicine or “food” that can treat all hair loss diseases. However, the stimulation of ginger juice may be effective in the treatment of alopecia areata (lack of clinical studies to support this), so patients with alopecia areata may try it.
What should I look for before visiting a doctor for female pattern baldness?
The diagnosis of female pattern baldness is complex and requires consideration of numerous issues for differentiation. For example, whether menstruation is regular, whether sex hormone levels are normal, whether thyroid function is normal, whether there is nutritional deficiency (excessive menstrual blood, intestinal malabsorption, dieting, etc. can cause this), whether there is an autoimmune disease, etc.
The doctor will usually inquire in detail about medical history, menstrual history, life status, mental sleep status, eating habits, any other diseases, medication history, family history, etc.; check the distribution of hair all over the body, body posture, etc.
Some laboratory tests will also be performed as needed: blood count, sedimentation, liver function, ferritin, vitamin B12, folic acid, vitamin D, blood glucose, insulin release test, thyroid function, thyroid-related antibodies, anti-nuclear antibodies, sex hormone level, sex hormone binding globulin, etc.
In some special cases histopathological examination will also be performed.
Patients should collect shed hair for hair microscopy prior to the visit. Collection method: After keeping your hair unwashed for 2-3 days, comb your hair thoroughly. When combing your hair, stand in front of a desk, lower your head and comb from back to front so that all the hair shed during combing falls on the desk, collect and organize these hairs. Note: Do not miss those tiny hairs when collecting hair. Then organize the paste into the following form: please hair roots face up. Finally, mark the number of hairs collected on the side.
Does a lot of oil on the scalp cause hair loss?
The oil in the scalp comes from the sebaceous glands, whose secretory activity is mainly controlled by androgens, which is why greasy hair does not occur until after puberty. The role of sebum is mainly to protect the skin and hair, but excessive sebum production will make both skin and hair greasy and prone to dandruff, which is unsightly but does not lead to hair loss. If the scalp is very greasy, minor inflammatory reactions such as seborrheic dermatitis or folliculitis can have an effect on hair growth, so it should not be ignored.
In patients with male pattern baldness, the hair follicles on the top of the head gradually become smaller under the action of androgens, and the corresponding local hair gradually becomes fine and thin, while the local sebaceous glands also produce a large amount of sebum under the action of androgens, so the two often appear together, making people mistakenly believe that the change in hair is caused by excessive accumulation of oil. With the development of modern medicine, it is clear that hair loss and oil production are not causally related, so oil control alone cannot play a role in preventing hair loss and growth.
What is androgenetic alopecia?
Androgenetic baldness, also known as seborrheic alopecia and premature baldness, is one of the most common types of hair loss in daily life. In Chinese men, the prevalence is nearly 20%, mostly occurring in the 20s and 30s; in women, the prevalence is around 5%, mostly in middle-aged and older women, but there are also patients who develop the condition when they reach puberty. The incidence of the disorder increases with age, and the degree of hair loss also increases with age.
What is male pattern baldness? What is female pattern baldness?
Androgenetic baldness can occur in both men and women. In most men, the frontal hairline gradually recedes, and the hair on the top gradually thins out and becomes thin and soft. This manifestation is male pattern baldness. Most female patients, unlike the former, retain their frontal hairline, while the hair on the top of the head thins out over a large area, and its degree gradually worsens, generally unlike the rapid development of male pattern baldness, which is called female pattern baldness.
How can I tell if I am suffering from male pattern baldness?
Generally speaking, this kind of hair loss mainly has the following performance.
1.Most of them start from the hairline on both sides of the forehead, and the hairline gradually moves back to the top of the head in an M-shape.
2. The hair on the top of the head gradually becomes thin and sparse, and the growth rate slows down.
3, finally appear obvious hair loss area, local skin shiny, residual a little fine soft short hair; and the back and sides of the head hair remains, often horseshoe-shaped appearance.
The above are the typical manifestations of male pattern baldness. If there is a lack of timely treatment, the hair loss will progressively worsen, and the time for treatment will be lost.
What causes male pattern baldness?
1, family genetic domestic research shows that 51.8% of male pattern baldness patients have a family history. A foreign study proved that the prevalence of hair loss in men whose father, mother or maternal grandfather had hair loss was about 2.5 times higher than the prevalence in men without a family history of hair loss.
2, dihydrotestosterone a substance called dihydrotestosterone (DHT) is the main factor that causes male pattern baldness. In men with male pattern baldness, the level of dihydrotestosterone (DHT) in the scalp increases, leading to the gradual shrinkage of hair follicles, making the hair thinner, decreasing the number of hair, and affecting the normal growth cycle of hair.
Can male pattern baldness be treated?
Proper and timely treatment can help you slow down the rate of hair loss and even regrow hair. The main treatment methods include internal medication, external medication and hair transplantation in conjunction with medication. Since male pattern baldness is a progressive disease, it should be treated as early as possible, and the earlier the treatment, the better the results.
Due to the slow growth of hair, it usually takes about 3 months to slow down hair loss, 4-6 months to regrow hair, and 1-2 years for the best results. Therefore, it is important to set reasonable treatment expectations, build up a long-term battle mentality, and not to give up treatment because of slow results.
Is female pattern baldness treatable?
The pathogenesis of female pattern baldness is more complex than that of male pattern baldness and often requires more detailed clinical and laboratory tests to determine if there are other genetic and endocrine abnormalities. Generally, treatment is based on topical medication, followed by oral medication with anti-androgenic effects, depending on the case.
