Salon goers all have one thing in common: No matter how much time they spend in their stylist’s chair, some terms on the color service menu can still be a bit confusing. While some hair color trends and techniques come and go, there are a few that you’ll always need to know about. Case in point: single and double process hair color.
What exactly is the difference between a single vs. double process hair color? We spoke to Nancy Braun, L'Oréal Professionnel brand ambassador and colorist, who broke down what you need to know about both color services. Whether you’re looking to go blonde or stick with brunette, keep scrolling for everything you need to know.

What is a single process hair color?
In a single process hair color service, the colorist applies one color throughout your mane to create a new base shade. According to Braun, many women also look to single process color as a way to cover up grays.
“You’re doing a global application all over the head...Usually, the purpose of doing a single process is either to lighten the hair, darken the hair, which includes covering gray, or changing the tone,” Braun explains.The service can also be an easy choice for women who want a fresh shade, but not a ton of effort or commitment.

Who says black hair is boring? The hue looks striking as an all-over color and leaves hair with a shiny, reflective finish.
What is a double process hair color?
If you’ve ever gone from a deep brunette shade to platinum blonde in just a few hours, you’ve probably experienced a double process hair color before. Stylists use double process color, or what Braun refers to as a “bleach and tone,” to lighten the hair by two or more shades in one session. The colorist will first bleach the hair completely, then tone it to create your desired shade.
“First, you lighten it to the desired level, which is usually a pale yellow or pale clear yellow...The second part is putting a toner on it to adjust the tone,” Braun says.
When it comes to coloring your hair, you should expect to be left with a bit of damage. Since double process color requires bleach, Braun warns it may not be best for anyone already dealing with extremely damaged hair or breakage.
“If the hair is really damaged, then it’s just a service that you probably shouldn’t do,” she explains.
