Pure 6A-grade mulberry silk, in Cuivre oxblood.

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.

Silk lets hair slide instead of catch, and it does not wick the serum out of your scalp the way cotton does. The treatment stays where you put it.

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