Does a silk pillowcase really change a hair care routine?

It doesn't replace any product, but it preserves what your products already do overnight instead of letting cotton absorb them and add friction that undoes your styling.

How often should I wash a silk pillowcase used for hair care?

Roughly once a week is enough for most routines, since silk doesn't absorb oils and products the way cotton does — hand wash or a gentle machine cycle in cold water keeps it in good condition.

You Style at Night, Then Undo It All on Cotton

Serums, leave-in conditioner, a final brush before bed — most hair care routines end at the pillow, as if nothing happens for the next eight hours. In reality, cotton absorbs a large share of those products and adds friction that undoes smoothing and definition while you sleep, so you wake up needing to restyle from scratch.

Add One Step: Change What Your Hair Touches All Night

Switching to a silk pillowcase doesn't add a step to your routine, it protects the ones you already do. Silk's non-absorbent surface keeps your products where you put them instead of soaking them into the fabric, and its smoothness means less overnight frizz to fix in the morning.

      "The best hair care routine in the world still resets every night on the wrong pillowcase. Silk is the one product-agnostic upgrade that protects whatever routine you already trust.
