Do you go to bed with wet hair? Find out why you shouldn't.

It's common to want to relax with a nighttime shower, and sometimes going to bed with wet hair seems tempting. However, dermatologist Trinidad Montero, a dermatology specialist, warns that this habit can seriously damage your hair and affect its health.

Why you shouldn't go to bed with wet hair?

1. Deterioration of the hair cuticle
Sleeping with wet hair affects the cuticle, the outer layer that protects the hair from external aggressions. When hair is wet, water droplets penetrate the cuticle, weakening it and leaving the hair more vulnerable to damage. This can lead to brittle hair, split ends, and a significant loss of shine.

2. Increased risk of infections
Wet hair creates an ideal environment for the growth of microorganisms, such as the Malassezia fungus, which can cause problems like seborrheic dermatitis, itching, and flaking. It also facilitates the growth of bacteria such as Staphylococcus aureus , which can cause scalp infections.

3. Aesthetic problems and tangles
In addition to the health risk, sleeping with wet hair increases hair fragility. Moving around in bed during the night can cause tangles and breakage when you style your hair in the morning, which can lead to further hair damage and the need for more frequent trims.

4. Bad odor on the scalp
Excess moisture promotes the development of unpleasant scalp odors, caused by the accumulation of microorganisms. Keeping your hair wet overnight not only affects hair health but can also generate an unpleasant odor.

To avoid all these problems, it's best to always go to bed with dry hair. Make sure you dry your hair properly: use a microfiber towel that absorbs excess water without damaging the cuticle, or partially air-dry your hair. If you prefer to use a hairdryer, opt for a low or medium temperature to avoid heat damage.

Caring for your hair goes beyond just washing it: maintaining good drying habits is key to maintaining its health and appearance.
