The top of the head is like a mountain, and the hair is like branches and leaves, thick, black as night and fluffy as clouds, but if it is hair loss and white hair, the head is either pale or sparse, which will also make people sigh.

Everyone wants to have a "nervous" hair, but why do the same people have different hair, black and white? It has been scientifically proved that hair is affected by many aspects of the body, including nutrition, endocrine, neuropsychiatric factors, etc.

The first is nutrition: hair, like other organs and tissues, needs enough nutrition besides enough calories to satisfy hair growth. Hair metabolism is centered on hair follicles, which have low respiratory rate and insufficient absorption of oxygen. It is necessary to supplement various nutrients, mainly protein, fat, vitamins and trace elements. Simply put, 97% of the hair is protein, and protein determines the elasticity and thickness of the hair; Trace elements of iron and copper determine whether the hair color is black; On the other hand, vitamins determine the softness and luster of hair. Therefore, if you want good hair, you must keep your body supplying blood and nutrition.

Endocrine is the main reason that affects the normal growth of hair, especially the secretion of hormones, which not only forms a key turning point in the early physiological development of men and women, but also affects the growth cycle of hair for life. Facts have proved that both androgenic alopecia, female diffuse alopecia and postpartum alopecia are related to hormone secretion, and the softness and sturdiness of hair are also related to hormone secretion.

Mental factors will directly affect the normal operation of head capillaries. Persistent insomnia, nervousness, panic, anxiety, or sudden nervousness will all lead to the blood supply disorder of the head microcirculation, so that the papilla under the hair follicle can not get the nutritional supply of blood, resulting in alopecia areata, alopecia and white hair.

Knowing the three factors that affect hair, you will know how to eat reasonably, regulate internally and externally, and maintain a good life mentality. These three points are also necessary for health preservation. If you are in good health, your hair and appearance will definitely be better!
