Yes, I\u2019ve seen this done many times before by these fear-based activists. This was a crazy claim, with NO supporting evidence, but evidence isn\u2019t needed if the goal is to create irrational fear. &nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Dispelling Myths: Understanding the True Causes of Dark Nail Streaks<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here are the facts, dark streaks like this are a relatively common condition that occurs on the hands and feet of men, women and children who have never been to a nail salon so it is NOT caused by UV lamps and there is no reason to believe this can occur.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These dark stripes are very common around the world, mostly to those with dark skin and are relatively uncommon to those with pale skin. Many things can lead to the occurrence of these dark stripes, they happen when the cells in the nail matrix&nbsp;begin to produce melanin. This can be a result of pregnancy, nail biting, carpal tunnel&nbsp;syndrome, psoriasis, viral <a href=\"https:\/\/nailknowledge.org\/blog\/plantar-warts-causes-prevention-and-treatment\"  data-wpil-monitor-id=\"85\">warts<\/a>, hyperthyroidism, exposure to x-rays, phototherapy, medications, excessive iron in the diet, and many other things. In rare cases this could indicate the existence of a tumour, but these are FAR more likely caused by recreational sun exposure- not UV nail lamps.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">UV Nail Lamps: Separating Fact from Fiction in Nail Health Concerns<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The nail plate has a high natural SPF that protects the nail bed and the matrix&nbsp;is buried under a thick layer of skin, so it\u2019s VERY unlikely that UV nail lamps would cause such issues.&nbsp; These UV lamps have been repeatedly demonstrated to be safe as used. In short, there is no reason to believe this story no reason to believe this dark stripe was caused by a UV nail lamp, and there is no reason to believe the person who posted this information. Especially since she refuses to return my e-mails or communicate with anyone else who tried to contact her and follow up on these claims.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Personally, I suspect this is an entirely made-up story, which would mean those behind this nonsense were INTENTIONALLY trying to harm the business of salons everywhere. That&#8217;s becoming commonplace. &nbsp;Fear-based activists regularly attack the nail industry with misinformation to sow fear and they often dupe the news media into spreading their trickery. That&#8217;s why it is so important that nail professionals become more educated about the nail and nail products, so they can fight back against these tricky deceptions.&nbsp; Don\u2019t be fooled, get the facts from someone who knows.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Empower Your Nail Expertise with &#8216;Face-to-Face with Doug Schoon<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">I create the &#8216;Face-to-Face with Doug Schoon&#8217; book series to equip nail professionals with accurate information and dispel internet myths.
