How to use hair dye

Everyone loves beauty. In today's society, people pay more and more attention to their own image and the beauty of their hair. Hair dyes are often used. Some are used by the elderly to dye their gray hair black, and some are used by young people to dye their hair into various colors they like in pursuit of fashion. This highlights a problem - how should hair dyes be used. If hair dye is used incorrectly, it can easily cause skin allergies, and in severe cases, pus and ulcers may occur.

So before using hair dye, the most important thing is to do a skin allergy test first. People who are allergic to hair dye must not use hair dye. The specific method is to apply a small amount of hair dye on the inside of the upper arm and a small area of ​​skin behind the ear. If symptoms such as redness, swelling, and itching appear within 48 hours, it means that you are allergic to the hair dye. In addition, be sure to use qualified products. During the hair dyeing process, be sure to protect your mouth, eyes, nose, etc., and try not to let the hair dye come into direct contact with the skin.

Don’t use hair dye too frequently. Generally speaking, two to three times a year is enough. Moreover, when using hair dye, do not mix multiple hair dyes together, because some hair dyes will produce chemical reactions, which can cause great damage to your hair and skin. Hair dye should not be used for a long time. The medical community has proven that long-term use of hair dye can cause cancer. Therefore, it is recommended that you only use it when necessary, and use it as little as possible or preferably not at all.

Moreover, expectant mothers, women who are planning to have a baby or are breastfeeding should never use hair dye, otherwise it will have a serious impact on the health of the child. For friends with low immunity, try not to use hair dye. In addition, if you don’t dye it yourself, you must go to a regular institution. It is particularly important to emphasize that if you experience symptoms of hair dye allergy, first wash off the hair dye as much as possible with warm water, and then go to the hospital for treatment in time.
