Can a pillowcase really make dandruff worse?

Yes, for dandruff caused by a dry scalp. Cotton absorbs the little moisture your scalp retains overnight and its rough texture physically dislodges flakes through friction. A 100% mulberry silk pillowcase, like Silkhouse's, doesn't pull moisture from the skin and glides over the scalp instead of scraping it, helping reduce mechanical flaking.

Cotton: A Sponge That Dries Out an Already Fragile Scalp

Dry-scalp dandruff isn't caused by excess oil, but by a lack of hydration and a damaged skin barrier. Cotton, a highly absorbent fiber, wicks away the little moisture your scalp manages to retain overnight, worsening the dryness. Worse, its rough, uneven weave rubs against the scalp with every movement, physically loosening flakes that would otherwise have stayed in place.

Silk: A Surface That Respects a Fragile Scalp

Mulberry silk doesn't pull moisture from the skin the way cotton does, and its perfectly smooth surface glides over the scalp instead of scraping it. Less friction means fewer flakes dislodged mechanically, and a scalp that keeps more of its own hydration through the night.

"A common mistake: piling on rich creams and oils at night on cotton, which absorbs most of the treatment before it can act. Switch to a silk pillowcase first — it lets your scalp care actually stay where you put it."
