The picture I linked is of a buckwheat pillow. Had no idea they were a thing before today.
What about silk or bamboo pillow cases?
I’ve only ever really used cotton pillow cases and cotton stuffed pillows. I recently upgraded to a foam pillow that I’m enjoying.
Silk pillow cases are really useful to people with curlu and cooled hair! Cotton pillow cases makes that kind of hair super frizzy, but a silk case can be softer on the hair meaning your curls are still intact in the morning :) Often people will use a silk wrap or hear wear instead of a silk pillow as they can ve cheaper and keep your hair more secure. It’s personal preference but can really help reduce frizz! Hope that helps
