Best Pillow Cases to Prevent Frizzy Hair and Help with Allergies

As well as matching your duvet cover, your pillow case should be comfortable to sleep on.

Most duvet sets come with matching pillow cases, but if you need to buy spare ones or extras, there are a few things to think about. Aside from matching the design of your duvet, fabric type will be very important. Some, such as silk, are better for reducing friction and static, which can be better for your skin and hair. The closure can also be important, as this can affect how easy it is to put on and take off, and it can even reduce allergens. And of course, there’s the size and shape, which can vary from brand to brand. Here’s what you need to know.

  • Size: In the U.K., standard pillows measure 20 inches by 26 inches, or 51 centimeters by 56 centimeters. Depending on whether you use a pillow protector and whether it’s padded, you may need a pillow case that’s slightly bigger than the standard size. It’s also worth bearing in mind that some fabrics will shrink a little in the wash. Most sellers will mention both of these points in the product description to help you choose the right size.
  • Material: Fabric is another important consideration and the reason why many people buy additional pillow cases. Silk is often thought of as the best for reducing hair damage and even wrinkles, but it’s much more expensive and can be difficult to care for. Cotton and polyester are both widely available and affordable, but the latter tends to be less breathable, which means it might not be great for hot sleepers.
  • Closure: The closure on pillow cases can make a huge difference. Zip closures are great if you want to keep out the allergens and they are also easier to put on. But envelope closures look more stylish and you don’t have to worry about catching the pillow in the zip. For envelope closures, look for a deeper flap as this will help hold your pillow in place.
