Dr. George Cotsarelis, a professor of dermatology at Perelman College of Medicine at the University of Pennsylvania, USA, said sleeping with wet hair is not good for health . Over time, water degrades the protective outer layer of the hair follicle, or epidermis. When the epidermis is broken, water can penetrate and break inside the shell of the hair follicle. Hair will be fibrous, prone to shedding, not shiny.

Dr. Adam Friedman, dean of the Department of Dermatology, George Washington University School of Medicine and Health, says anything you do with your hair, such as combing, drying, coloring, or exposing your hair to the sun, is available. Can damage the hair.

"You can use conditioner to repair and repair the damage caused by these factors on the hair," Mr. Friedman said.

Besides, sleeping when wet hair is harmful to the skin. People with the habit of sleeping on their stomach or lying on their stomach, wet hair in contact with the pillow and face can cause some irritation. As the water in your hair evaporates, your scalp and face lose moisture all night.

According to Mr. Friedman, in some cases, wet hair can help you sleep better. Many studies show that cooling the head at night helps to calm the metabolic activity of the brain, so people can sleep quickly and deeply.
