O’Connor’s favorite way to restore hair—be it straight, curly, damaged, or color-treated—is to double up on treatments by following the Cleansing Purifying Scalp Scrub (above) with this mask. It pairs prickly
pear seed oil, an antioxidant-rich oil that helps to smooth and repair super-dry or brittle hair, with nourishing plant ceramides. “It makes hair soft, shiny, and easy to manage afterwards,” she says. “It’s also light enough that you can use it on all hair types, but if you have fine hair, start off with a small amount on your ends and go from there to make sure it isn’t too heavy.”
