Kathleen Hou from The Cut reports that Kim Kardashian’s quick-change comeback from white-as-eff platinum back to dusky dark locks sans damage is due to a single treatment: Olaplex. I tried this pre-wash treatment last week (it’s on Amazon) and I was MADLY enamored. I was about 3 months deep into a haircut (I know, my goal is sister-wife hair. DEAL.) and my ends were, as you’d imagine, an utter scandal. 10 minutes of this stuff pre showering and my hair was smoother, healthier and far less frizzy. You know if Kim is shilling something this hard gratis, it’s good. Get into it.
