Last week I posted about whether or not it’s better to blow dry or air dry your hair. I saw this brilliant reels of @thepasinis where Alessio told his wife not to go to bed with wet hair because it can lead to breakage of the hair, and he is so right! 🙋‍♀️For once and all: wet hair is more weak than dry hair and is more likely to break. Every type of hair is more weak when it’s wet (from straight to curly to African hair). So be careful with wet hair. Water makes the hair swell. When the hair is wetted, the inner cuticles (hair surface) swell, but the outer cuticles remain rigid and do not swell. This leads to cuticle lifting off (is damage of the cuticle = coarse and rigid feeling hair). This cuticle lifting is even more induced when the hair is stretched or moved, i.e exactly what happens with your hair while sleeping. Moving around your head in your sleep (something we all do) against the pillow causes constant moving and stretching of the hair fibres, which can lead to breakage of the hair. 🙋‍♀️Wet hair and your scalp: Wet hair can cause a problem for your scalp health, this has mainly to do with fungus. Our scalps are home to a large variety of microbes, most of these are pretty innocent. However, some microbes (like Malassezia globosa) can be more harmful. Malassezia globosa is totally naturel but causes irritation, dryness, itch and flakes (dandruff) in about half the world’s population. Of course, it’s not the end of the world for your hair, but going to bed with wet hair is not doing any good to your hair. If you can’t dry it before going to bed, at least apply a conditioning agent which reduces the friction (while moving your head) and loosely (!) tie your hair (don’t let it down). If you can dry it before going to bed, make sure to dry it at low temperature settings (and preferably use a heat protectant). Do you (often) go to bed with wet hair?
