Many people think that it’s no big deal if you sleep with wet hair. However, the truth is much worse than you may think. Research shows that you should have a dry, or at least damp hair before you go to bed. To be more specific, you need about 4 hours for your hair to be completely dry (naturally of course). So, don’t go to bed earlier than that.

Possible Side Effects Of When You Go To Sleep With Wet Hair
1. Hair Breakage

This is the most common problem that people face when going to bed with wet hair. Hair breaking happens because the hair is most vulnerable when it’s wet. So, all that swirling on the pillow case is the possible reason for split ends and flyaways. You don’t want this for your hair, don’t you?

2. Itching And Dandruff

Itching and dandruff are the second possible cause of sleeping with wet hair. Namely, the humidity disrupts the pH value of the scalp, causing dandruff.

In addition, yeast-like fungi may also be the reason of skin shedding. That’s why wet and moist environment can make your dandruff condition even worse. If you already have dandruff, avoid sleeping with wet hair. Blow dry it on a cool air, or wait for it to dry naturally. When it’s completely dry, off to bed.

3. Headaches

Sleeping with wet hair can cause headaches. The water cannot dry or evaporate when you press your head against the pillow case. Thus, your scalp takes up the excess water, which may trigger a headache.

An additional cause can be the positioning of your head. If you sleep on your back, the back of your head will be wet longer in the night. This may further cause additional problems, which often lead to shoulder pain. If you suffer from chronic headache, it’s better to first dry your hair and then go to sleep.
