Perms are back in style and they're certainly not what they used to be. Instead of giving you a mess of frizzy curls, as was popular in the 1980s, modern perms tend to provide you with waves and curls that are much more sleek and relaxed — but, can they still cause damage to your hair? While new perm formulas are generally less damaging than older ones, they can still potentially harm your hair by changing the chemical composition of your hair cuticle (via Well+Good).

烫发又流行起来了，而且肯定不是以前的样子了。现代烫发不像上世纪80年代流行的那样，给你留一头乱糟糟的卷发，而是更加光滑和轻盈——但是，它们还会对你的头发造成伤害吗?虽然新的烫发配方一般来说比老式的危害小，但它们仍然可能通过改变头发表皮的化学成分而对头发造成潜在伤害。

"Perms get a bad rap because, ultimately, it is a chemical process that permanently changes the hair, which can affect the hair if done incorrectly or if the hair was already chemically processed," Priscilla Flete, a New York City-based hairstylist, told Well+Good. "The real damage happens when you apply your next perm after perm after perm, which causes breakage." According to Flete, perming and coloring your hair at the same time can also cause damage.

纽约发型师普里西拉·弗利特在接受Well+Good采访时表示:“烫发之所以名声不好，是因为它是一种永久性改变头发的化学过程，如果处理不当或头发已经经过了化学处理，就会影响头发。”“真正的伤害发生在一次又一次地烫发，这是导致头发断裂的重要原因。”弗利特说，烫发和染发同时进行也会造成伤害。

How to care for your perm

怎样保养你的烫发

Proper aftercare is key to maintaining your new perm. That's why it's important to avoid doing certain things right after getting it done (via InStyle). For instance, if you don't want to ruin your new hairdo, you should avoid washing your hair for at least three days. "I only recommend washing sooner if you want to break up the curls to achieve a softer, semi-permanent beachy-waves look," celebrity hairstylist Sascha Breuer told InStyle.

正确的护理是保持新烫发的关键。这就是为什么要避免在烫发后马上做某些事情。例如，如果不想毁掉新发型，应该至少三天不洗头发。名人发型师萨沙·布鲁尔在接受InStyle采访时表示:“如果你想破坏卷发的弧度，让它变得更柔软、不那么持久，那么可以早点洗。”。

It's also important not to style your perm with anything other than your fingers. That's because brushes and accessories can cause breakage or give your hair an undesirable shape. If you can't comb your hair with just your fingers, you can use a wide-toothed comb after conditioning your perm in the shower. In addition, you can protect your perm at night while you're asleep by wearing your hair in a scarf or bonnet. This will help prevent your curls or waves from getting flattened.

同样重要的是，不要用手指以外的任何东西来梳理头发。这是因为刷子和配件会导致头发断裂，或者让头发形成不想要的形状。如果不能只用手指梳理头发，那么可以在淋浴时使用宽齿梳子。此外，在晚上睡觉的时候，可以戴上围巾或帽子来?；ぬ谭ⅰＵ饨兄诜乐咕矸⒒虿ɡ吮淦?。
