Pure 6A-grade mulberry silk, in Kaviora champagne.

Cotton drags on hair all night — that friction is what leaves you with a frizz halo and snapped ends by morning. Silk lets hair slide instead of grip, so the repair you did in the bath is still there when you wake up.

It also stops your pillow drinking the treatment: cotton wicks oil and product straight out of the lengths, silk leaves it where you put it.

Details: 6A mulberry silk both sides · 50 × 75cm housewife style · hidden envelope closure · machine washable on a cool delicate cycle.
