Pure 6A-grade mulberry silk, in Cuivre oxblood. The cap and the pillowcase, together.

You spend eight hours a night with your scalp and lengths pressed into cotton. Cotton grips — that friction is what wears the cuticle at the mid-lengths and snaps the finer regrowth before it ever gets long enough to see.

The cap holds the parting still overnight — the crown, the temples, the hairline — and keeps the serum on your scalp rather than on the pillow. The pillowcase protects everything that has already grown.

Details: Sleeping cap — 6A mulberry silk lining · generously cut with ribbon ties · soft elasticated band that will not mark your forehead. Pillowcase — 6A mulberry silk both sides · 50 × 75cm housewife style · hidden envelope closure. Both machine washable on a cool delicate cycle.
