“Always put on sunscreen,” “you should bring a jacket,” and “if you can’t say something nice, then don’t say anything at all.” Yep, mom knows best. But what about all those times she warned you about sleeping with wet hair? We investigate.
First of all, sorry mom, but falling asleep with a head of wet hair won’t actually give make you sick. Quick health class: The common cold is caused by a virus that has nothing to do with the temperature or dampness of your tresses. But that doesn’t necessarily mean you want to make a habit out of it.
That’s because your hair is weakest when it’s wet, which means that going to bed with water-logged strands could potentially damage the hair shaft. This may increase the likelihood of breakage and tangles. But keep in mind that the experts we spoke to stressed that occasionally crawling into bed with damp hair won’t cause much noticeable damage. Doing it every other night for weeks or months, however? Probably not such a great idea.
Per Phil Mania, owner of Mania Hair Studio: “Sleeping on wet, untreated hair can cause frizz, flyaways and possible breakage. Let your hair air-dry until it’s at least damp or use a hair dryer to quickly get some of the moisture out and apply a product that’s specific to your hair texture.” (Just remember to wash your pillow frequently to avoid product buildup.)
