Throughout the years of bleaching and toning my hair various shades, I’ve tried many different oils and K18’s is easily one of the best I’ve ever used. When applied to damp hair after showering, it helps tame my usual puffiness; when used on dry, styled hair, it adds a touch of moisture and shine. Featuring the brand’s K18Peptide, it fills in the broken polypeptide chains that make up our hair, repairing damage from the inside out. Honestly, the science behind the oil is cool but my favorite thing about it is that it actually feels lightweight, so rather than sit on top of your hair like many oils tend to do, it sinks right in.
