"为了和偶像同款发色，我几乎每个月都补染一次头发，没想到竟染出了肾病。"近期，一则"00后 女生追星频繁染发确诊紫癜性肾炎"的消息在微博发酵，话题阅读量迅速突破千万。看似寻常的染发行 为，为何会与肾脏疾病相关联？频繁染发存在哪些健康风险？在追逐潮流与维护健康之间，我们应如何 理性权衡？带着这些问题，科技日报记者采访了多位专家。 奚丹特别提醒："有些人可能存在未知的轻度肾功能不全，频繁接触染发剂中的化学物质可能加速肾病 进程，导致急性肾损伤或慢性肾病加重。对于健康人群来说，频繁染发也有可能会导致化学物质在体内 累积，逐步造成慢性肾脏损伤。" "染发烫发还可能带来其他健康风险，比如脱发、头皮发炎、皮肤过敏等。"天津市泰达医院皮肤科主任 医师陈保疆说。 有些人染发后会出现头皮发红、瘙痒、脱屑等症状，更有甚者头皮和面部还会出现水肿、水疱等更为严 重的过敏反应。"染发剂中的任何一种成分都可能诱发过敏，哪怕是天然植物染发产品或无氨、无对苯 二胺的产品，也可能会使人过敏。"陈保疆举例说，"比如天然染料海娜花，其核心成分散沫花素就容易 致敏。对本身就是过敏体质的人群来说，染发时更要谨慎。" 染发剂属于化学药水，频繁使用可能会 ...

肾脏是人体主要的解毒器官，负责过滤血液中的废物和毒素。当大量对苯二胺及其代谢产物等进入 血液后，肾脏需加倍运转以完成过滤与排出工作，这无疑会加重肾脏负担。"长期或高浓度的化学物质 暴露可能直接损伤肾小管和肾小球细胞，导致炎症反应，进而影响肾功能。"奚丹解释说，同时，它还 可能作为半抗原与体内蛋白质结合形成完全抗原，引发免疫复合物沉积在肾小球基底膜上，导致免疫炎 症反应——这正是紫癜性肾炎的主要发病机制。 此外，一些不合格的染发剂中可能含有铅、铁、铜、汞等重金属，会在染发时被人体吸收。其中， 铅需经肾脏代谢，频繁使用该类染发剂也会对肾脏造成损伤。 "为了和偶像同款发色，我几乎每个月都补染一次头发，没想到竟染出了肾病。"近期，一则"00后 女生追星频繁染发确诊紫癜性肾炎"的消息在微博发酵，话题阅读量迅速突破千万。看似寻常的染发行 为，为何会与肾脏疾病相关联？频繁染发存在哪些健康风险？在追逐潮流与维护健康之间，我们应如何 理性权衡？带着这些问题，科技日报记者采访了多位专家。 对苯二胺加重肾脏负担 天津市第一中心医院皮肤科主任医师奚丹说，染发确实有可能引发肾病。大部分染发剂中都含有一 种名为对苯二胺的化学物质，这是染 ...
