Silk pillowcase or sleep cap: which better protects your hair?
Pillowcase or cap: what do you want to protect?
At night, friction damages hair: cotton snags the hair fiber, creating frizz, knots, and breakage upon waking. Mulberry silk offers a smooth surface that allows hair to glide and limits this friction.
The pillowcase acts passively: you sleep normally, and it protects your hair and skin. The cap envelops the hair and keeps it in place — more targeted, but you need to remember to put it on every night.

How to choose — or combine
Choose the pillowcase if…
You want a simple gesture that also protects your skin, without changing your bedtime routine.
Choose the cap if…
You have very dry, curly or frizzy hair, or a structured hairstyle (braids, blowouts) that you want to preserve for several nights.
Combine both if…
You are looking for maximum protection: the cap envelops the lengths, the pillowcase protects the face and acts as a safety net if the cap slips.
