If you lose a lot of hair, even more than 100, then you need to go to the hospital for examination, which may be caused by the increase of testosterone after exercise. But most people don't have this phenomenon. In addition, when it comes to testosterone, both men and women will secrete it. Men are secreted by testicles and women by ovaries. Testosterone is also called androgen, which can promote the increase of bone density and muscle growth, improve human physique and enhance metabolic activity.
Generally speaking, after exercise, male hormones will be secreted more, which is a normal reaction to promote bone density increase and muscle growth, and will strengthen metabolism. Your hair will grow more vigorously after your metabolic activity is enhanced. If you are a boy, your beard will grow faster than usual as long as you exercise regularly. If your metabolism is faster, your hair will fall out faster, but it will also grow faster. Reducing and increasing basically has no effect on your hair volume.
Generally speaking, it will not cause hair loss, and testosterone will not cause hair loss, but for some people, there are some special circumstances. Generally speaking, the doctor's advice is to eat as many vegetables and fruits as possible, to maintain physical and mental peace, and to stop exercising.
That's a special situation. Generally speaking, exercise will not lead to hair loss, but will lead to faster hair growth. However, if you feel that it affects your mood, you can slowly reduce the exercise effect to see your hair loss. If your hair loss has not changed, it means that it is not caused by your fitness. You should check other things, such as the shampoo you use, whether you stay up at night and the food you usually eat.
