all hair types Sleeping with Wet Hair: Is it Bad?

Calling all people who prefer night showers to morning showers: this one’s for you! If you shower at night, chances are you hit the hay with wet hair more often than not. Ever wonder if there are repercussions to sleeping with wet hair—or if there is a proper way to sleep on hair? If questions like, “Can sleeping with wet hair make you sick?” and “Does sleeping with wet hair cause headaches?” have ever crossed your mind, you’ve come to the right place. Is it bad to leave your hair wet when catching up on your beauty sleep? We’re answering all of the above and more, below.


Let’s get down to it—is it bad to sleep with your hair wet? There are actually a few concerns people tend to have about sleeping on wet hair, so let’s dig into which are fact and which are fiction.

1. Can sleeping with wet hair make you sick? You may be familiar with your mother or grandmother telling you not to go outside with wet hair for fear of catching a cold, but what about sleeping with wet hair? Can it make you sick? According to a study from the National Center for Biotechnological Information (NCBI), the belief that the common cold can be caused by wet hair is, in fact, nothing but a myth. So in short, no; sleeping with wet hair won’t make you sick!

2. Does sleeping with wet hair cause headaches? Another common thought is that sleeping with wet hair can result in headaches. Is there truth behind this statement? Turns out, per a study from the NCBI, there is some research that suggests wet hair in cold weather can be a shaping factor for sinus headaches. That being said, more research needs to be done.

3. Can sleeping with wet hair damage your strands? Most importantly, you may be wondering if sleeping on wet hair can cause damage to your locks? Unfortunately for those who shower at night, the answer is yes. This is because your hair is at its most fragile state when wet. In fact, the American Academy of Dermatology (AAD) states most people should handle wet hair as little as possible because wet hair breaks more easily. This means acts done while sleeping, such as tossing and turning or sleeping on a rough pillowcase can cause breakage and split ends to occur.

Due to the fragile state of wet hair, the AAD recommends allowing your hair time to partially air dry before styling or combing. As a rule of thumb, this suggestion should also be applied to sleeping on your strands. If you don’t want to give up your night showers, consider leaving a few hours between your shower and bedtime to give your hair time to dry, or try using a blow-dryer (with a heat protectant, of course) to prevent sleeping on wet hair.

4. Does sleeping on wet hair lead to knots and disarrayed styles? A few knots may not be as concerning as getting sick or causing damage to your hair, but it is a concern when it comes to sleeping on wet hair. If you tend to move a lot while sleeping, knotty hair can certainly be a result. You may also notice that you aren’t quite as happy with how your hair looks after sleeping on it wet. However, there are ways to pull off cute, knot-free styles even if you sleep on wet hair. More on that next!


Find yourself sleeping on wet hair? There are a few wet hairstyles you can sleep in to help protect your hair and make sure it looks good upon waking.


Is it bad to braid wet hair? No! Just allow your hair to dry a bit before brushing and braiding it. It’s best to work with damp hair for this wet hairstyling option. When your hair is partially dried, spritz with the L’Oréal Paris Advanced Hairstyle AIR DRY IT Wave Swept Spray, then braid your hair as you wish (we recommend a French or Dutch braid) and hit the pillow. When you wake up, unweave your braids to reveal beautiful waves.


Prefer the look of looser waves? Allow your hair to partially dry, then pull your locks into space buns at the top of your head. Simply split your hair in two and twist each section around itself, forming a bun. Pin your buns into place with plenty of bobby pins, and in the morning, let down your hair and show off those waves.


If you don’t want to wake up with waves, wrap your hair in a silk hair scarf before going to bed. This will prevent any friction between your strands and pillowcase and eliminate any added frizz in the process. In the A.M., you can also use the scarf to style your strands!
