Silk pillowcase – does it work for hair growth?

By July 1, 2019 Hair growth tools

Sleeping on silk bed sheets no longer reserved for the riches. Silk has been produced for millennia and its strength, smooth texture have been praised throughout recent human history and some pretty astonishing findings like surviving complete flooding for over a century and still remaining intact.

Sleeping on a silk pillowcase however has distinct benefits to manageability of hair as well as health and appearance of your skin. While silk will not directly make your hair grow, it does have significant benefits to the hair that has already grown.

Mechanics of sleeping on silk

Because of its smooth texture, your hair and skin glides on its surface rather being caught by the harsh fibres – as it tends to happen when sleeping on more commonly spread, cotton pillowcases. Usually, during sleep, especially if not using protective hair styles, hair strands rub against one another leading to hair cuticles stand up leading to dull, frizzy hair. In addition, cotton is a highly absorbent material – it wicks away the natural moisture present in your hair and skin – making your hair strands further more prone to breakage and wicking away natural moisture from your skin.

When it comes to skin case, the product that you put on your face before going to bed often gets absorbed by the cotton pillowcase you might be sleeping on – rather than by your skin. After trying sleeping on silk ourselves and seeing the outstanding results (hello smoothness and shine!) there was one thing that bugged us – and that’s the humanity and sustainability of silk and its natural and man-made textile alternatives. Behold an in-depth overview of textile production, be warned that some details of silk production may be too graphic, which made us feel highly guilty going to bed on silk pillowcase, but throwing it away would make it even worse making the cruelty having happened in vain.

Silk: a tale of silkworm’s life

Silk is a natural fibrous polymer consisting of amino acids. Silk fibers consist of 97% protein – fibroin, a filamentous protein (approximately 75%) and sericin, a non-filamentous protein (nearly 25%). The fibres are produced by certain insect larvae to form cocoons. First the larvae are being fed and maintained at a farm and sometimes fed only specific type of foods, e.g. mulberry leaves which produces mulberry silk. The silk farmers then heat the cocoons to kill them, leaving some to metamorphose into moths to breed the next generation of caterpillars. Harvested cocoons are then soaked in boiling water to soften the sericin holding the silk fibers together in a cocoon shape. The fibers are then unwound to produce a continuous thread. Since a single thread is too fine and fragile for commercial use, anywhere from three to ten strands are spun together to form a single thread of silk. Each moth produces about 1 mile of single thread in one cocoon.

The boiling alive part of sericulture (cultivation of silkworms to produce silk) is what has the animal rights protectors horrified. So we have considered other options when it comes to beauty and keeping those hair of yours nice and shiny…

Ahimsa “peace” silk

Otherwise known as “peace silk” – ahimsa, in the Hindu, Buddhist, and Jainist tradition is respect for all living things and avoidance of violence towards others. Ahimsa silk is produced slightly differently from usual silk – which affects its quality as well as poses some important question about its cruelty-free factor.

Instead of boiling the cocoons with the larvae alive inside, the moths are allowed to hatch. This causes the tear in the cocoon affecting the uniformity of the silk thread. In addition, while the silkworms don’t get boiled alive – moths might meet another type of death – once hatched, moth, through generations and generations of breeding simply did not evolve to have sufficient strength in their wings to lift up the body in order to go and hunt for food. Essentially this leads to the moths dying of starvation.

Ahimsa silk usually leads to 10 extra days in the process to let the larvae grow and the moths to hatch out of the cocoons. In contrast, the less humane process takes about 15 minutes. Such difference leads to higher cost of ahimsa silk fabric. In addition, because of using torn out silk thread this affects quality of the fabric itself – it is claimed to be softer to the touch than usual silk.

Polyester

Polyester is a synthetic petroleum-based fibre and is therefore made from a carbon-intensive non-renewable resource, like any other oil-based products. Nearly 70 million barrels of oil are used each year to make the world’s polyester fibre, which is now the most commonly used fibre in our clothing. But it takes more than 200 years to decompose. In addition, it is not bio-degradable and will persist in the ecosystem even as it eventually breaks apart. While washing, tiny particles of fibres make their way into the oceans producing micro plastic pollution of our ocean, its flora and fauna. Essentially, it also comes back to us, in the form of fish and seafood we consume.

There is a number of ways to prevent seeping the micro plastics into the oceans by using filters on your washing machine, not washing your fabrics too often or use micro plastic laundry bag that catches the micro plastics before they get into the sewer system of your city.

Viscose

The lyocell fibers, like other cellulosics, are moisture absorbent and biodegradable. They fibers are made from wood or plant pulp, have a dry strength higher than other cellulosics and approaching that of polyester. Viscose does however have limitations – it absorbs moisture, therefore negating the effect that sleeping on a silk pillowcase gives to your skin and hair.  This can discolour and weaken the fabric and result in marking. In addition, production of cellulose exerts pollutants into the environment.

Conclusion

At The Hair Fuel, we would absolutely love to offer pillowcases that would offer the same benefits as silk pillowcases for your hair, since we ourselves have seen the result in the form of shiny hair with pronounced waves and glowing skin as a result of sleeping on it. And therefore we are presented with the choice of vices. Whether it is cruelty to silkworms, environmental pollution – in 2019 it seems that you need to choose yours in the pursuit of beauty.

As a guide we would suggest considering sateen weave made from cotton if you want to minimise your cruelty and environmental impact – however it may not deliver as good a result as an actual silk pillowcase.
