Coloring your dark brown hair with brown hair dye that lasts is easier said than done. One major option is low ammonia hair color, which is frequently touted as much easier on hair. But what ultimately decides how long the color will stay?

The Function of NH3 in Brown Hair Dye

It could have to do with how frequently you wash your hair, the type of shampoo you use, the amount of time you spend in the sun — as crazy as that sounds — or even the oils that occur naturally in your hair. Dark hair has more natural pigment, so it holds color from low-ammonia dyes longer than lighter hair, Monahan says. 

The Reason Low Ammonia Dye Causes Color Fade

Color fade occurs with all hair dye, but it may occur more rapidly with low ammonia products. This is because not as much of the dye is allowed to penetrate in the hair shaft. Sun, chlorinated water and heat styling are just some environmental factors that make color fade more quickly.
