Frequently Asked Questions

How should I choose a root touch-up product?

Step one of choosing a root touch-up product is finding the right shade—easier said than done. That's why it helps to call in reinforcements. New York City-based colorist Aura Friedman, who's worked with Lady Gaga and Sky Ferreira, suggests reaching out to your usual colorist for guidance. The good news? That doesn't necessarily mean a trip back to the salon. Some colorists, like bicoastal expert Rachel Bodt, even offer FaceTime consultations. "Picking the right shade can be so overwhelming," she says. "FaceTiming is a great way to connect with my customers and help people."

Once your shade is settled, it's time to choose your format. The right pick can depend on how much product you're comfortable using. "A spray applicator will dispense the most product, a shaker uses an average amount, and a brush will use the least amount," explains New York City-based hairstylist Devon Toth. "Sprays are great further from the hairline and on your part. It can cover that up, but you don't want to spray too much near your face." Toth recommends shakers for areas with thinning and powders with brushes for hairline recession. Speed is another factor. If you need quick, on-the-go coverage, a compact powder or spray is your best bet. For a more comprehensive camouflage, a dye will seal the deal.

One more thing: People with highlights need to make sure they match the overall tone of their hair or even spray more than one color to recreate the dimension at the roots. It doesn't need to line up perfectly with their actual highlights but it will help make it all blend.

Should people with highlights cover up roots differently than people with grays?

"People with highlights need to make sure they match the overall tone of their hair or even spray more than one color to recreate the dimension at the roots," says Toth. "It doesn't need to align perfectly with their actual highlights but will help make it all blend."
