Old man with black hair is bad for the body
Many elderly people are very keen on dyeing hair in order to make white hair black.
Multi-country studies have shown that the incidence of people who regularly dye hair, pregnancy, skin cancer, leukemia, and bladder cancer will increase.
In particular, middle-aged and elderly people, due to low resistance and reduced immunity, are more susceptible to toxic reactions, contact dermatitis, and even tumors than young people.
The probability of young people dyeing color is relatively small, which is often associated with color dyeing, often without contact with the joint between the hair root and the scalp.
In the middle-aged and elderly people with white hair diabetes, it needs a large area, or even the whole head is black, which causes the skin to absorb hair dyes year after year. The body base is relatively poor and the metabolism is slowed down, so it is more susceptible to allergies and carcinogenesis.
Patients with diabetes and high blood pressure, high blood pressure should be carefully dyed; patients with allergic diseases such as diabetes, sores, skin ulcers, blood diseases and tumors should stay away from hair dyeing.
If the old man really wants to dye hair, try to go to a professional hairdressing salon; do a skin test before dyeing; choose a semi-permanent dye.
Middle-aged and elderly people should not change their hair color too much, and do not replace hair dyes. Because some hair dyes do not have the same chemical composition, if they are replaced, they will increase the risk of causing cancer and cancer.
However, if scalp itch, redness, rash and other symptoms appear after dyeing, stop using the hair dye. If there is systemic symptoms such as dizziness or fatigue, it may indicate systemic toxicity. It is recommended to go to the hospital for examination.
In addition, elderly people who often dye their hair should also go to the hospital for a physical examination.
