许多人都有指甲周围长倒刺的经历，这些倒刺不仅影响美观，还很容易引起疼痛。为了省事，很多人习惯顺手撕掉，这种错误方式会让你感觉特别痛，甚至还会出血。

当手指出现倒刺时，长辈总会说是平时蔬菜吃得少，缺维生素了。事实果真如此吗？人为什么会长倒刺呢？

为什么会长倒刺

Despite what its name suggests, a hangnail isn't part of a ripped nail still tenuously1 attached to the base. It's a sliver2 of skin that hangs off your finger on either side of your nail. Though it often seems like they pop up out of nowhere, they happen when the skin around your nails gets weak and brittle3 to the point of cracking.

“倒刺”并不像它字面所指是一根倒长的刺，而是指挂在指甲两侧的一小块手指皮肤。倒刺看似是无缘无故冒出来的，但其实当指甲周围的皮肤变得脆弱、易破裂时，才会长倒刺。

"They can result from a variety of things, like biting your nails, a bad manicure, dry skin, using harsh soap and detergents4, cold temperatures, and 'waterlogged' hands,'" dermatologist5 Dr. James Collyer told GQ.

皮肤科医生詹姆斯·科勒博士告诉《GQ》杂志：“倒刺可能是多种原因造成的，比如咬指甲、修甲不当、皮肤干燥、使用粗糙的肥皂和洗涤剂、低温和手部长期浸水。”
