Hair sub-health detection

Yellow hair is not necessarily a sign of sub-health. Because there are many reasons for hair yellowing, there are congenital factors and acquired factors. For example, some people's hair is naturally yellow, not black, which may be hereditary, but it doesn't mean that they are in poor health. Acquired factors are about people's health. It is also simple to distinguish between congenital factors and acquired factors. If his hair is naturally yellow, his hair will be very soft. If properly maintained at ordinary times, his hair will not appear rough, which is very different from the yellowing of hair caused by sub-health state of the body.

Psychological state and life pressure will make hair yellow. If the stress in our life is too great, the direct manifestation is that our hair turns yellow. This is because the endocrine disorder of our body is caused by our psychological state, and the production of melanin and its related substances in our body is hindered, so it is directly manifested as our hair turning yellow. In daily life and work, we must adjust our mentality, work and rest rules in time, and don't be picky about food. If we feel that we can't stand it, we must consult a psychologist.

Furthermore, if there are some trace elements in the body, or there are some problems in the body, then the hair will turn yellow. For example, hypothyroidism or severe iron deficiency anemia can cause hair to turn yellow, because these diseases will reduce melanin in our body. Health is the capital of revolution. If you feel unwell, you must seek medical advice in time, and don't put it off until the end. This is not only bad for the health, but also increases the difficulty of treatment.

Picky food or some external conditions can also make hair yellow. Because of picky eaters, some trace elements in our body can't be supplemented, so our hair will turn yellow, which is a common symptom of children. Furthermore, if the hair is exposed to the sun for a long time, it will turn yellow without good protection.

The above is my opinion, I hope it will help you.
