There’s no doubt we have stars like Rachel McAdams and Kate Middleton to thank, in large part, for our obsession with face-framing layers. The look is multi-faceted, and works for a variety of hair types because it adds an optical effect of greater volume to thin strands and eliminates weight for thicker textures. Layered styles are also among the easiest to maintain and produces a natural second day texture when air dried—this creates an ideal canvas for playing around with color (especially ombre or multi-tonal variations).
