For hair and skin, a silk pillowcase or another pillowcase that reduces friction is usually the best choice. Real silk is popular because it feels smooth, does not tug on hair as much, and is comfortable for facial skin.

A good alternative is cotton satin or high quality viscose satin, which can also provide slip and less friction than rough cotton. Avoid very rough or highly absorbent fabrics if you struggle with frizzy hair or dry skin, since they can create more friction and draw out moisture.

Also choose a good fit so the pillowcase does not twist around, wash it regularly because skin and hair products can build up, and pair it with hair friendly habits such as a loose braid and soft hair ties.
