Hair · with your mask
Thermal Deep-Conditioning Cap
5.0 8 reviews
A foil-lined cap that holds in your own warmth while a hair mask or oil sits, so it stays warm, even and drip-free, and hair rinses out feeling silkier and looking glossier.
Compatible: Made to pair with the Rice Water & Keratin Hair Mask, but it works over any rinse-out mask, conditioner or hot-oil treatment you already use.

Ten warm minutes, once a week

Apply your mask

Good to know
Questions, answered
It doesn’t generate heat, it keeps it. The foil lining reflects and holds the warmth your scalp naturally gives off, so your mask stays warm and workable instead of cooling and drying out.
Any rinse-out mask, deep conditioner or hot-oil treatment. It’s made to pair with our Rice Water & Keratin Hair Mask, and the two together cost less as The Deep Conditioning Ritual.
Ten to twenty minutes is the sweet spot for most masks, or whatever your product’s directions say.
Wipe the lining with a damp cloth and let it air-dry. It’s reusable, not a disposable shower cap.
