The reason why boys have less leg hair is related to the amount of androgen secretion in the body, heredity, health condition and other factors, and may also be related to factors such as vascular occlusion.
1. Leg hair belongs to a kind of body hair, and its growth rate and density have a close relationship with the body’s androgen secretion. From the normal situation, boys leg skin surface will be distributed with a small amount of sweat hair, in the case of strong secretion of androgens, sweat hair on the legs will become more dense. Comparatively speaking, in the case of less androgen secretion, the sweat hair will appear more sparse.
2. The thickness of the hair is related to genes. People with sparse body hair in the family will have a higher chance of having less leg hair.
3. The density of hair is also related to the health condition, for men with good nutritional status and good physical condition, the hair will be relatively thicker.
4. For cases where the skin on the legs is excessively smooth and there is no visible leg hair, it may be related to factors such as vascular occlusion.
For men who have less leg hair, they need to go to the hospital in time.
