The product: Vidal Sassoon Salonist ($15)

Why we want it: There's no argument: professional hair color comes out way better than when you use the tube at home. Here's why: the brush. Stylists often brush on color at the roots, and now you can do the same using this pro-grade kit. Then, just add the serum to thin out the product for the ends.
