If smooth, silky hair is what you're after, grab yourself a can of Sachajuan Straight and Shine Spray. Spritz it on damp hair before an at-home blow-out to tame frizz and get an extra-sleek style, or use it on dry hair to prevent heat damage from your flatiron. We tried it one morning before work and must have been asked 50 times: "Did you just get a blow-out?" All right, five times. But still!
