Briogio Rosarco Oil
For hair that's taken a beating, this blend of rose hip argan, and coconut oils is a lifesaver. High in essential fatty acids, the mix calms frizz and increases hair's hydration so it's less likely to snap. The formula also contains radish-seed extract to amplify shine. To reap the benefits, apply a drop or two from midlength to ends of wet or dry hair.
