The silk pillowcase provides a smooth, soft surface that significantly reduces friction compared to cotton pillowcases.

This reduction in friction is beneficial for the hair, as it limits frizz and reduces the formation of tangles while sleeping. Silk allows hair to maintain its natural shine and luster.

Additionally, it can help prevent sleep creases on the skin, as the softness of silk limits the pressure placed on the face during sleep, reducing the chances of wrinkles forming and preserving the skin's natural radiance.  ;

Due to its delicate texture, silk pillowcase helps maintain skin hydration, as it absorbs less moisture than other materials like cotton.
