Since we spend a third of our lives in bed and our hair is worn against the pillow every night, a frictionless pillowcase is crucial for good hair quality. The smooth surface of the silk pillowcase reduces hair breakage, split ends and frizz. The shiny surface also prevents tangles and bed-head, which leads to less breakage when brushing. As silk pillowcases do not absorb moisture or skin oils, your pillowcase stays fresh and doesn’t make your hair greasy. Mulberry silk contains 18 essential amino acids, which are found naturally in our own hair. The amino acids are known for their effectiveness in skin nutrition and are believed to prevent aging.

Silk pillowcase as skin care

Silk is naturally hypoallergenic, contains sericin and is resistant to dust mites, fungus, mold and bacteria, unlike ordinary cotton pillowcases. Silk lets your skin breathe and the prevents pores from clogging. Because silk does not absorb moisture, your face stays hydrated all night. An important plus for many is that the minimal friction reduces fine lines.

Mulberry silk

Mulberry silk got its name from the mulberry leaves on which the silk worms feed. The butterfly caterpillar spins the silk fiber around itself before they are finally transformed into butterflies. This fiber finally becomes the exclusive and magical fabric we love - Mulberry silk.


Momme is a way to measure the quality of silk. Fabric quality is usually measured based on density, but since silk is so thin and silk consists of so many threads, Mulberry silk is instead measured in weight - Momme. The higher the momme, the higher the weight and quality.

The standard for silk bedding is usually between 12-16 momme, while SOÀs products are all in 22 momme. A pillowcase in 22 momme contains 20 times more silk thread than a pillowcase in 19 momme.

Pillowcases made in lower momme are significantly cheaper to produce and therefore more common on the market. A pillowcase in 22 momme contains an ideal amount of silk and lasts for several years longer than silk pillowcases in lower momme.


In addition to all the benefits for hair and skin, silk pillowcases are very comfortable to sleep on. Many people experience that ordinary cotton pillowcases feel like sandpaper in comparison with the smooth surface of mulberry silk after they once got used to sleeping on silk. Mulberry silk is also naturally temperature-regulating, which feels cool on hot summer nights but keeps the heat when it is cold.


Mulberry silk is a natural fiber and can easily be burned to ashes without harming the environment.All Soà Stockholm's silk products are OEKO TEK-certified, which means that no harmful or environmentally hazardous chemicals have been used in production.
