Lu Tao, director of the dermatology department of the Affiliated Hospital of the Armed Police Medical College, said that people’s skin is relatively fragile in summer, their pores are wide open, and they are affected by sun exposure, so they are more susceptible to hair dye allergies.
According to the US Food and Drug Administration, each brand of hair dye is used per 10,000 people, and 15.2 of them have adverse reactions. Clinically, the adverse reactions caused by hair dyes are mostly allergic. Most of the symptoms are itchy skin, erythema, papules, and even blisters, redness, pain, and exudation.
Director Lu Tao suggested that the number of hair dyes should be minimized. If hair dyes are used for special needs, natural hair dyes should be used instead of chemical hair dyes.
Hair dyes for natural pure plants should be approved by the Ministry of Health. Read the instructions carefully before use to understand the ingredients and methods of use. Don’t be cheap, choose low-grade inferior products.
Before choosing a hair dye product, it is best to apply the hair dye to the skin behind the ear without wounds, sores, etc. If there is no abnormal reaction within two days, the hair can be dyed. Before dyeing hair, be sure to keep your skin condition normal.
