Hair follicle injury leads to permanent hair loss, and short-term hair follicle injury leads to temporary hair loss. Permanent alopecia is a common male alopecia. In some European countries, the male baldness rate is as high as 40%.
The process of permanent alopecia (male alopecia) is gradually produced. At the beginning, the hair margin of the head and forehead was obviously retracted, and the hair on the top of the head was scarce; Then it will develop gradually, and finally it will develop into only a circle of sparse hair on the back of the head and on both sides of the head. There are three main reasons: genetic factors, lack or disorder of androgen in blood circulation; Overweight. In addition, scars left by various skin diseases or skin injuries, congenital hair dysplasia, serious hair follicle damage caused by chemical substances or physical reasons, etc., may all cause permanent hair loss.
Temporary hair loss is often caused by diseases with high fever. However, X-rays, ingestion of metals (such as thallium, tin and arsenic) or drugs, malnutrition, some skin diseases with inflammation, chronic wasting diseases and endocrine disorders can also lead to temporary hair loss.
There are two ways to treat male pattern alopecia. The first type is hair transplantation, that is, the hair follicle of the scalp with long hair is transplanted to the place with short hair, that is, from the back of the head to the front. The second method is local application. Minoxidil is often used for external use, which can effectively prevent alopecia caused by various reasons and promote hair regeneration in bald or sparse parts.

First, the purpose of hair care is to maintain the health of hair, and at the same time can overcome dandruff or hair loss.
To prevent hair loss, we should start with daily hair care. Here are the basic methods of hair care.
First, shampoo and hair care.
Hair cleanliness is the foundation of hair quality health, and correct washing method is an important factor to maintain hair.
Dry hair has less sebum secretion, and the shampoo cycle can be slightly longer, usually once every 7 ~ 10 day.
Oily hair has more sebum secretion and a slightly shorter shampoo cycle. Usually wash once every 3 to 5 days.
The sebum secretion of neutral hair is moderate, and it is usually washed once every 5 to 7 days.
For dry hair, choose mild and nutritious shampoo and hair care products, and for oily hair, choose shampoo products with stronger detergency.
The correct method of washing hair is also very important for hair maintenance, which mainly includes the following steps: combing hair, washing hair with clear water, washing hair with shampoo, using conditioner, and absorbing moisture in hair with dry towel.
Nursing hair
Dry hair and damaged hair should be oiled 1 time every week to supplement hair oil and moisture. Massage the head for 10 ~ 15 minutes every day to promote blood circulation, supply epidermal nutrition and promote the secretion of sebaceous glands and sweat glands.
Use a small amount of olive oil after shampooing. Neutral hair oil 10 ~ 15 times, massage the head 3 ~ 4 times a week, each time 10 ~ 15 minutes, and use a small amount of hair cream after shampooing.
Trim hair
When the hair grows to a certain length, the ends of the hair will split and break easily. Regular pruning can avoid this phenomenon and keep your hair healthy and shiny. At the same time, regular pruning can also stimulate the metabolism of hair cells and stimulate hair growth.
Fluffy hair
Hair is an appendage of the skin. If it sticks to the scalp, it will affect the breathing and excretion of the skin and cause pathological phenomena of the scalp and hair.
Be careful with perm.
Excessive perming will damage the keratinocytes of hair, making hair dry, inelastic and even split and broken. It is advisable to have a perm once every six months, and choose a curling iron core with a slightly larger diameter. The perm time should not be too long.
Reasonable diet
Hair is made up of cells, and the metabolism of cells needs a variety of nutrients. Therefore, a reasonable diet is an important factor in supplementing nutrition to hair. Protein, carbohydrate, fat, vitamins and minerals are the nutritional sources of healthy hair.
