Ms. Zhou told the reporter that she is a fashion-conscious woman, and due to high requirements for personal image at work, she frequently gets her nails done, using beauty to "arm" herself from head to toe. She has already listed getting her nails done as a must-do item in her notebook and insists on getting her nails done twice a month. "There hasn't been any problem for two years, why am I so unlucky this time!" Ms. Zhou lamented. The reporter found that, for the convenience of medical examination, Ms. Zhou had washed off the nail polish on all ten fingers. Without any coating, her nails were not only yellowish but also lacked luster, with some nails showing signs of breakage and damage. Long-term manicures can lead to "onychomycosis" (commonly known as "gray nail"). Besides "gray nail", paronychia is another common nail infection caused by manicures. In the step of removing dead skin, it is necessary to cut the dead skin around the nail edge. Once overdone, it easily causes skin injury or even bleeding, allowing bacteria or fungi to invade, causing redness and inflammation on both sides of the skin, forming paronychia. If it recurs, it will eventually become a chronic paronychia that is difficult to cure. Frequent nail trimming can also lead to paronychia. "Frequent nail trimming can cause nail deformities, thickening, unevenness, and lack of luster." Dr. Zhu Minghua said, when asked about children's cough medicine. Some patients seen in the outpatient clinic showed nail deformities such as outward curling. Upon further inquiry, it was discovered that they were also enthusiastic about manicures. Dr. Zhu Minghua stated that while manicures can make nails look more beautiful, they also come with health risks. "My nails have become thick and lack luster, which turns out to be related to my frequent manicures!" Ms. Zhou regretfully said after being diagnosed with an unsightly gray nail. Experts pointed out that many beauty-conscious white-collar women have their nails beautifully adorned, some even get their nails done once a week without paying attention to hygiene. Over time, their nails become thicker or more fragile and opaque, and they may even contract "gray nails", paronychia, or blood-borne infectious diseases due to manicures, resulting in losses outweighing gains. The reporter also personally witnessed the process of a manicure at a nail salon upstairs in a mall in Tianhe: first soaking the dead skin of the ten fingers to soften them, then using a dead skin knife to scrape off the softened dead skin around the nails, followed by using a sanding board to shape and smooth the nails, and finally applying one or two layers of nail polish.
