Part of the reason that balayage is so popular is that it doesn’t require touch-up trips to the salon; it will grow out very naturally. Keep an eye on the color and simply repeat the process whenever you think your color needs a pick-me-up, every 2-3 months. You can even let your balayage go longer and transition it to an ombre look. To keep your highlights looking fresh, opt for a color-correcting shampoo and conditioner combo that won’t fade your dye prematurely. Using products made for dyed hair will also keep your highlights from getting dark or brassy. If you have have naturally blonde hair, keep your highlights from turning brassy or yellow by using a purple shampoo or spray once or twice a week. However, don't use it too often, as it can give your hair a purple tint. Even the small amount of hair dye used in balayage can dry out your strands, leaving them stiff and hard to style. To keep your hair healthy, apply a hydrating hair mask once a week. You can buy a hair mask at a beauty store or online, or make your own. To make keep your hair healthy and moisturized, rinse and wash it with cool or lukewarm water instead of hot water, which can strip moisture. It’s also best to shower every other day or once every few days; washing your hair too often can make it dry and brittle.
