Dad Liu, 67, lives in Honggang City, Qingshan. In recent years, more than half of my grandson's hair has turned gray. Last Saturday, he went to the supermarket, and the shopping guide recommended him a hair dye called herbal formula. Dad Liu immediately paid for a box. The morning after dyeing his hair, Dad Liu felt the scalp itch badly and ran to the barber shop to wash his hair. Inadvertently talking about his itchy scalp after dyeing his hair, the clerk told him a little secret: washing his hair with light salt water can alleviate the hair dye allergy. After returning home, dad Liu washed his hair as usual, but he didn't expect to wake up. He was shocked by himself in the mirror: his whole face was red and swollen and vivid, and he quickly went to the nearest Wuhan Puren Hospital. Li Renqing, director of the Department of Beauty and Plastic Surgery, was diagnosed as contact dermatitis caused by hair dye after examination and had to receive desensitization treatment immediately.
"Never be superstitious about pure plant hair dyes." Li Renqing revealed that hair dyes completely extracted from plants can't be dyed for a long time. Almost all hair dyes on the market have added chemical components, but the dosage is different. He introduced that p-phenylenediamine is an indispensable component in hair dye, which can fix color on hair, but it is extremely allergic, ranging from edema, erythema to bullae, and even all over the body.
Li Renqing reminded that you must have an allergy test before dyeing your hair. Dilute the hair dye and apply it to the inside of the wrist. Once the skin is itchy, red and swollen or abnormally irritating, rinse it off with clear water immediately.
