Why is it not good to sleep with wet hair?

With the heat, sleepless nights increase and, to relieve hot flashes and be able to sleep, solutions that are far from healthy are often used. This is the case, for example, of showering late and going to bed with wet hair. Going to bed without drying your hair is not highly recommended , as humidity not only damages your hair , but can also cause negative health effects.

Problems sleeping with wet hair

Increased hair sensitivity to water and the cuticle

Firstly, if hair is kept wet for too long, it becomes more sensitive. This is due to one of its properties called hygroscopic, which allows it to absorb moisture from the environment. Thus, water is introduced into the cuticle and it increases its size. As a consequence, the proteins and components of the hair are looser, that is, they are not compacted as when it is dry and, therefore, they can be lost. That is why when it is wet, it is more sensitive to any force or manipulation.

Increased porosity of the capillary surface

As a result of this sensitivity, the hair becomes more brittle and will be damaged more easily. It can dry out, split, etc. after the continuous rubbing with the pillow. It will also increase the porosity of the capillary surface, making the hair weaker, this being one of the most common causes of hair loss.

Inflammation of the scalp due to humidity

In addition, the humidity contained for so long, either by sleeping with wet hair or by wrapping it in a towel, causes inflammation of the scalp. All this can lead to a very annoying itching sensation that, without avoiding it, will make the person who suffers it scratch, running the risk of producing injuries that, most likely, will increase the itching.

Relationship between dandruff and humidity

On the other hand, the worst enemy of dandruff is precisely humidity. By sleeping with wet hair, the life of a fungus that inhabits the head called Malassezia , which usually feeds on the fatty oils of the follicles, is modified to carry out cell renewal of the scalp. However, with water its process is altered. It multiplies and reproduces faster, increasing cell turnover and, as a consequence, causing the appearance of dandruff.

Tangles and knots in the hair

Going to bed with wet hair is synonymous with tangles. The evaporation of water during the night tends to cause knots in the hair, and the movements of the head during sleep are not at all conducive. The attempt to remove them will lead to greater hair loss , by forcing its untangling.

Other problems sleeping with wet hair: headaches and colds

Do not forget that the inconvenience of sleeping with wet hair can also lead to health problems. For example, it can cause severe headaches, headaches, or muscle aches. You can even wake up with a cold due to a sudden change in temperature.

Why is it bad to sleep with wet hair?

Going to sleep with wet hair can cause problems such as: greater capillary sensitivity and increased porosity of the capillary surface; inflammation of the scalp due to humidity; dandruff; tangles and knots in the hair; as well as headaches and colds.

Recommendations

In any case, it is important to dry your hair before going to bed, although it is not convenient to abuse the dryer either. It is best to rub it gently with a towel and use a wide-tooth comb to detangle and prevent hair loss. If the loss persists, it is best to contact a hair health specialist.
