Androgenic alopecia, also known as premature alopecia, mainly occurs at the age of 20~30. This kind of hair loss becomes slender and sparse from the temples on both sides of the forehead, and the areas on the top of the head and forehead are also invaded, and the hairline keeps retreating, leaving a typical M-shaped or V-shaped baldness.

This kind of hair loss will be affected by certain genetic factors, such as Prince William, who has been losing his hair for generations, which fully embodies the tradition of hereditary baldness of British royal men.

If your father, grandfather and grandfather all lose their hair, there is a great chance that they will not be absent from you.

In fact, the relationship between androgen and hair loss. At present, the theory holds that testosterone, especially dihydrotestosterone, is the first suspect that leads to hair follicle atrophy. Can make the hair follicle "atrophy", shorten the hair growth cycle, reduce the density, and lead to hair loss.

Reason 2: Postpartum alopecia

Estrogen in pregnant women is strong, and the level of estrogen decreases after delivery. In contrast, the proportion of androgens increases in disguise, and hair follicles are sensitive to androgens, which leads to the inability of hair to adapt to the changes in the proportion of androgens and androgens, and the number of hair entering retrogression and rest increases.

Fortunately, under normal circumstances, the hormone level will stabilize again after 6 months, and postpartum hair loss will basically stop slowly. When the baby 1 year-old, the hair of the mothers will grow back slowly.

So don't be too anxious, you know, you are not alone.

Reason three: stress and daily anxiety.

Hair follicle is the smallest organ in human tissue, and it is really not easy to put it on the top of your head. It provides nutrition for about 50,000 organs in the human body.

Our brain is very powerful, although it only accounts for 2% of the human body, but it consumes 40% of the energy. When the brain is in an excited (anxious) state and the workload increases, the demand for blood will also increase. A large amount of blood will first meet the needs of the brain through the internal carotid artery, and the amount of blood delivered to the top of the head by the external carotid artery will decrease sharply.

The nutrition of hair follicle hair can not be guaranteed, which affects the normal growth of hair.

This situation can easily lead to alopecia areata, just like the forest where the hair is exposed to the sea. This situation is called Mediterranean alopecia.

Reason 4: Lose weight and lose hair.

Some women are hard on themselves when they lose weight. I want to lose weight quickly through a strict diet and fasting plan.

When losing weight, "collective hair loss" vividly shows that even the hair is protesting against the owner's excessive weight loss.

Reason 5: middle-aged greasy hair loss

It is found that high-fat diet structure will increase male androgen, lead to hair loss and excessive sebum secretion, squeeze the growth position of hair roots and hinder blood circulation.

Reason six: disease alopecia

Scalp yellowing and serious infectious diseases, such as burns and scarlet fever, can also cause serious hair loss.

Hair loss should be treated early.

Therefore, young people in their twenties, once they find themselves bald, should treat their hair loss as soon as possible, otherwise they will not be able to touch the hairline in the future.

First check whether there are problems with stress, mood, rest, diet, etc. Changing bad diet and eating habits is the first prerequisite. We should fundamentally adjust our ability to resist stress, or learn to vent our emotions.

If not, we can also plant hair. There are about 654.38+ million hair follicles on the scalp. We can transplant some strong hair follicles from the area near the back of the head to the hair loss area.

Finally, a n experienced person gave young people four suggestions:

Health is more important than anything else.

2. Exercise and fitness are several investments with low input and high harvest.

3. The simplest and most difficult advice: go to bed early and get up early, eat on time, eat reasonably, sleep hard, and keep on studying and exercising.

The best skin care product is sleep.
