The first point is that dyeing hair is very harmful, especially some fake and shoddy products. The pungent smell can make people have a splitting headache. When the hair is often dyed, the hair dye cream itself will also cause some harm to people's health. So try not to dye it.
Second, white hair in your fifties is normal and you don't need to hide it. A man knows his destiny when he is over 50. At this time, they can't accept that they are old, and white hair will be generated continuously. In fact, this is a normal phenomenon, but it is difficult for our own psychology to accept white hair and even dye hair. Actually, you don't have to do this. Sometimes you can look younger with white hair!
Hair dye itself is composed of chemicals, but chemicals have certain side effects. The most direct harm to the body is that it is particularly prone to skin allergies. After long-term use of hair dye, it will cause chronic burns to the body and skin, skin cancer after deposition under the skin, and may also lead to seborrheic dermatitis. My sister is allergic to hair dye. Once I dyed my hair, my whole face was deformed, my eyes were swollen into a crack, and my scalp was itchy. Later, she went to the hospital and took anti-allergic drugs. Since then, no matter how white her hair is, she has never dyed it.
Compared with beauty, health is of course the most important.
Secondly: dyeing hair regardless of age.
Some friends have high demands on their appearance and can't stand their white hair, which is very common among friends of all ages around them. Another friend, Juvenile Bai, began to dye when she was young. I really don't agree with those children who dye their black hair grandma's gray color in the street. When friends dye their hair, it is best to apply some hair cream on their forearms to see if there is any allergic phenomenon. If yes, stop using or switch to other brands of hair cream.
I am in my fifties, and my hair has just turned white, black and white. It doesn't matter if you look at home at ordinary times, but you still have to tidy up when you are away. At least, I need my energy. Don't give people the feeling of being dirty and sloppy.
