The answer is, yes! Sleeping with wet hair can hurt your hair as it poses several risks. It may result in hair breakage and increase the risk of developing fungal infections on the scalp. This article discusses why you should never sleep with wet hair and certain safety precautions to follow. Scroll down for more information.
Why You Should Never Sleep With Wet Hair
Sleeping with wet hair may cause:
Hair Breakage
The hair is at its weakest state while wet and is more prone to damage. When the hair is wet, the cuticles open up, exposing the inner parts of the hair shaft. At this point, the hair is weak and may get damaged easily if not handled properly. Moreover, damaged, dry, frizzy, low-porosity, and heat and color-treated hair is already weak and may end up getting more damaged when wet.
Fungal Infection
Fungus loves warm and damp environments, and sleeping with wet hair may increase your risk of scalp infections. The warm and damp conditions may promote Malassezia’s growth, a yeast-like fungus that causes dandruff and dermatitis. Moreover, the pillowcases and pillows may expose your scalp to fungi like Aspergillus fumigatus (1). This may cause scalp infections that affect the hair follicles and may weaken them, causing hair fall.
Sleep Issues
Sleeping with wet hair can lead to sleep issues as it impacts your body’s ability to regulate temperature. When you sleep with damp hair, moisture on your scalp and hair can lower your body temperature. This might cause discomfort or a chill and disrupt your sleep cycle as your body attempts to regulate its temperature while you sleep. The dampness can create a breeding ground for bacteria or fungi, which may cause irritation, itching, or other problems with the scalp and make it harder for you to get a good night’s sleep. It may also be simply difficult to relax and fall asleep if your scalp feels cold. There might be circumstances when you do not get the chance to dry your hair before hitting the bed, or you may not have access to a blow dryer. In situations where you cannot avoid sleeping with wet hair, it is best to take preventive measures to avoid any damage. Here are a few things you can do.
How To Sleep More Safely With Wet Hair
1. Apply Coconut Oil
Studies show that applying coconut oil for pre-wash and post-wash grooming reduces protein loss. It penetrates the hair shaft easily and reduces water sorption (2). This helps prevent hair damage and breakage. Note: Avoid coconut oil if you have seborrheic eczema, as it may worsen the condition.
2. Condition Your Hair
Conditioning your hair helps seal the hair cuticles. A good conditioner also minimizes friction and detangling. If you have bleached or chemically treated hair, a hydrating conditioner can reduce further damage and breakage.
3. Partial Drying And Detangling
If you do not have the option to dry your hair thoroughly, try to partially dry it (up to 70% or 80%) before hitting the bed. You can use a hair dryer ( if available) or shower earlier than usual to give your hair ample time to air dry. Less water in your hair will minimize the damage. Also, detangle your hair before bed to avoid extra stress on your hair.
4. Use Silk Pillowcases
Silk pillowcases minimize friction and prevent hair breakage. Moreover, unlike cotton pillowcases, silk pillowcases do not absorb hair moisture and may reduce the risk of infections, frizz, and breakage. However, there is no evidence to support this fact. Is sleeping with wet hair bad for your brain? No. Sleeping with wet hair has no connection to brain function. On the contrary, it may affect your scalp health as the dampness may lead to fungal infection, and you also risk catching a cold. There are surprising reasons why sleeping with wet hair might not be the best idea.
