Not to sound like hair color elitists, but when someone rocks a DIY dye job, you can usually tell it was his or her own handiwork with a flat hue, too-dark tone, and lack of shine as the major indicators.

Though grabbing a box of color from the drugstore might seem like a way to save time and money going to the salon, more often than not, we usually end up bothering our colorist to fix the damage after a botched job, but Vidal Sassoon's latest launch just might be the game-changer. With the same method and tools your colorist uses in the salon, Vidal Sassoon's Salonist is foolproof enough for anyone to master.

Instead of a sole bottle of dye for your whole head, the kit includes two coordinating hues---one for your roots, and one for your mid-lengths and ends---to impart a blended, multidimensional effect you'd otherwise need an appointment to achieve. "Over 80 percent of women who color their hair at home apply one formula to their whole head," celebrity hairstylist Duffy previously told InStyle. "Most hairstylists treat the roots and lengths of the hair differently to get color that is blended, and full of rich depths and tones."

Applying two different hues onto your head may sound like a recipe for disaster, but the science behind Salonist backs up the technique. The Vidal Sassoon team researched the hair fibers, structures, and surface properties to ensure each formula was just right, with a concentrated version to treat your never-dyed roots, and a coordinating glaze to cover the rest of your hair.

If you've colored your own hair before, the technique isn't too different from your usual regime. Start with unwashed strands, then use the included mixing bowl and brush to sweep on the rich color cream specifically formulated for the root area. Once your crown has been covered, mix the serum (step 2) in with the remainder of the color in the bowl to transform the mixture into a glaze, then coat your mid-lengths and ends in the emulsion.

Previously-colored strands tend to be more porous and soaks up more of the dye than the rest of the hair shaft, but because the glaze is more lightweight, you no longer have to worry about creating a too-dark effect. Pick up the Vidal Sassoon Salonist kit for $14 at drugstores nationwide starting right now ( for locations), and watch your #NewYearNewHair hashtag become a trending topic.
