Why you should never sleep with wet hair

After a long day, it can be extremely tempting to skip the hair dryer and go to bed with your hair still wet – but here’s why you shouldn’t.

Going to sleep with wet tresses can be disastrous for your hair health. From damage to the follicles, breakage, to fungal scalp infection, dandruff, frizz, and flyaway strands, the list is endless.

Coline Benjamin, owner of CELF Haircare, has given us seven reasons why should you stamp out the damp habit and only hit the hay once your hair is almost dry, either naturally or with the help of a hair dryer.

Breakage: Wet hair is weaker and more susceptible to breaking than dry hair, so sleeping on it at night could lead to breakage and split ends.

Bacteria: The moisture from your hair sinks into your pillow and creates the perfect environment for germs and bacteria to flourish. So, keep your hair dry and your pillows fresh!

Frizz: The friction between your hair and the fabric of your pillow can leave your hair strands unruly and frizzy when you wake up in the morning.

Bed head: Wet hair will dry and set in whatever position it’s in while you sleep, which can cause difficult tangles and knots.

Dull locks: Sleeping with wet hair can break down the hydrogen bonds that keep the hair shafts strong and silky, which can lead to brittle or dull hair.

Hair loss: Going to bed with wet hair can result in hair loss and, more specifically, disorders like scalp ringworm. Scalp ringworm is a type of fungal infection, caused by warm and damp conditions. It's highly contagious, so take care to wash anything that has come into contact with your scalp.

Dandruff: The warmth of your head and the prolonged dampness in your hair can cause bacteria and fungi to multiply on your scalp as well as your pillow. The combination of bacteria growth and the loss of natural oils can make your scalp more likely to develop dandruff, and one wouldn’t want any of that!

 “Everyone should make sure hair is not sopping wet,” she adds. “Hair shouldn’t be so wet that it leaves your pillow damp, make sure to let your hair air dry at least a bit before going to bed to reduce your risk for damage and dandruff.”
