Hair loss is a problem that people of every age group and gender experience. There are various reasons for hair loss, including genetic factors and some bad habits later in life. As winter approaches, many people find that they lose more and more hair in this period. The truth is that hair fall does get a little worse than usual in the fall and winter, it's like when the trees start to lose their leaves at this time. We call the hair shedding with the change of seasons as seasonal hair loss, also physiological hair loss, we do not need to be too nervous, but this period, we still need to take good care of hair.

The manifestations and causes of hair loss in different seasons

1. Spring

In spring, everything is flourishing, and the growth of hair is accelerated accordingly, so the demand for nutrients such as moisture and protein also increases.

However, the warm climate makes the moisture and oil of the hair evaporate easily, resulting in a dry scalp, dry hair lacks normal luster and elasticity, becomes brittle and dry, easy to break, so the phenomenon of spring hair loss is very common.

2. Summer

In contrast, summer is actually not a high incidence of hair loss. However, the high temperature make the scalp pores open more easily, accelerating the rate of hair metabolism, which leads to hair thinning.

At the same time, if there is no reasonable sun protection, the strong UV rays directly on the head will stimulate the scalp, making the collagen fibers degeneration, hair becomes fragile, thus affecting the growth and nutrition of hair, resulting in increased hair loss.

In addition, the summer heat makes sweat glands, sebaceous secretion significantly enhanced, sweating and oil and dust so that the cleanliness of the hair is not easy to maintain. Frequent washing can lead to baldness because of the damaged scalp environment, while inattentive cleaning risks itchy scalp, bacterial growth, and skin diseases.

3. Autumn

There are many different reasons why hair loss occurs in the fall.

First of all, in autumn, the growth of hair naturally slows down, and the dry climate also makes the sweat and sebaceous glands secrete less, the hair follicles shrink, and hair becomes dry and fluffy. Especially after a strong exposure to the sun in summer, the hair in the resting phase is more likely to fall out.

Secondly, the weather is getting cooler in autumn, so the hair does not adapt to the environment thus leading to dehydration, nutrient deficiency and so on. As the temperature gradually decreases, the temperature of the scalp also gradually decreases, the blood circulation in the head is insufficient, and the hair follicle tissue in the head lacks sufficient nutrition. When hair follicles encounter sudden changes in the environment, they will atrophy and the hair grown will wither or even stop growing, so severe hair loss often occurs in autumn.

At the same time, it has also been argued that hair loss in autumn is closely related to human health. According to Chinese medicine, the arrival of autumn makes the spleen and lungs function less well and cannot properly provide the nutrients needed by the hair follicles.

4. Winter

The cold and dry conditions in winter take away the moisture from the skin, while the sebaceous glands secrete even less. The lack of oil nourishment of the scalp accelerates the detachment of the cortical layer, leading to the production of dandruff.

In winter, when people wash their hair, they unconsciously raise the temperature of the water, and the high temperature stimulates the scalp to increase the expansion of capillaries and increase the evaporation of scalp moisture. Increased dandruff and damaged scalp make the scalp environment enter a vicious cycle in winter.

Plus the winter people's activity is reduced, the whole body blood flow, especially the highest scalp capillaries, more difficult to get circulation; at the same time, the temperature difference between indoor and outdoor, the temperature of the dramatic changes to stimulate the hair follicles, hair loss will follow.

In addition, many people will wear hats in winter, stifling heat, sweating will intensify the sebaceous glands secrete oil, if improper cleaning, easy to lead to inflammation of the hair follicle. Besides, people are willing to wear hats now, which may rub the hair to make it fall out more easily, and there is also the possibility of sweating and oiling. All are some behaviors that are not very friendly to the hair and scalp.

As the temperature changes from season to season, the temperature of the scalp echoes and decreases. As a result, the microvascular network of the scalp becomes inactive. Since the microfilament vascular network is directly transporting nutrients to the hair roots, and the hair roots are affected by this, the metabolism of nutrients is impaired, and the lack of nutrient supply to the hair roots leads to the lack of nutrients in the hair shaft, thus causing hair loss.

It seems that you are losing your hair all year round. Indeed, because hair has a growth cycle, falling out is a normal thing. Generally speaking, it is normal to lose between 50-100. You don't need to feel very nervous about normal physiological hair loss. You should read carefully about the main causes of hair loss in different seasons and then use the appropriate care methods to keep your hair healthy.
