Forget this bad habit and come to terms with your hairdryer!
If you might sometimes be tempted to wash your hair just before going to bed, remember to dry it well before you slip into your sheets. Indeed, sleeping with wet hair would be rather inadvisable for a lot of different reasons.
From a strictly practical point of view, sleeping with damp hair may give you a hard time the next morning. Hello, ears, knots, and other sticks that stick up that we will have to spend time taming.
But this is far from the only problem! Since the hair fiber is more sensitive and porous after shampooing, it also means that the hair will be more susceptible to damage and weakening when you put your head on the pillow. The friction and movements that one makes while sleeping can have significant consequences for the health of the hair: split ends, breakage, knots... so many inconveniences that we would prefer to do without.
In terms of hygiene and health, sleeping with wet hair is not very good either. Yes, our friends the bacteria love humidity because it allows them to proliferate more quickly. Who says wet hair also says pajamas and wet sheets, and therefore even more bacteria on the scalp and scalp. Enough to cause small health concerns that can be very annoying: such as dandruff, eczema, yeast infection, or irritation. The best way to make sure you catch a cold or a cold is to sleep with wet hair with the bedroom window open.
