When the human body wears a nightcap to sleep, due to the cover of the nightcap, it can reduce the loss of heat from the head (three-quarters of the human body’s heat is emitted from the hair), maintain the temperature of the scalp, and let the blood vessels of the head be in a state of relaxation. Keeping the blood flowing can play a role in promoting sleep. Because of the relatively stable temperature, it can also effectively prevent colds caused by cold at night. For women who love beauty, wearing a suitable nightcap can effectively fix the hair and effectively prevent unconscious turning over and mess up the hair styling during sleep. At the same time, due to the isolation of the nightcap, the friction between the hair and the pillow is reduced. Protect your hair on top. This silk nightcap is made of 6A grade 100% mulberry silk. It is smooth, soft, light and breathable, which is perfect for your hair and skin. We have 16mm, 19mm, 22mm, 25mm.
