Washing your hair impacts its appearance, but what you do afterward can lead to damage. Experts advise on the risks associated with sleeping with wet hair.
Dr. Anil Sharma, a medical professional at Sharma Skin & Hair Surgery, highlights the potential issues of going to bed with wet hair. He notes, “While it may seem convenient, sleeping with wet hair can have several downsides. Wet hair is more fragile and prone to breakage, which can cause frustration when you wake up.”
Damp hair is more delicate and can be damaged by movement during the night, leading to friction. Dr. Sharma also points out the increased risk of bacterial growth. “Sleeping with damp hair creates a moist environment ideal for fungal growth, such as Malassezia, which can lead to dandruff,” he explains. Although some cultures suggest that wet hair may cause headaches or colds, there is no strong scientific evidence to support these claims.
Hair washing frequency varies from person to person, and the techniques used can affect hair health. Experts from Roxy Hair, a luxury hair extension specialist, discuss the trend of double washing—shampooing twice rather than once. This method involves applying shampoo two times: the first to break down impurities and the second to ensure a thorough rinse.
Double washing is praised for cleansing the scalp and reducing dandruff risk. However, overuse can strip hair of natural oils, resulting in a dry, irritated scalp. Therefore, it’s advisable to use this technique occasionally.
