If your blonde hair is getting dull and brassy, Morales suggests popping into the salon for a clear treatment. “You don't have to wait for your next hair service for a gloss,” he says. “It refreshes color and removes brassiness in 15 minutes.”

Is your brown or red hair fading, but you're not ready for a full head of color? A color gloss deposits a small amount of color and amps up shine. “If I have a brunette that starts getting light or brassy, I'll do a quick color gloss to get that rich shade back,” Morales says.

Single-process color means one shade of hair color is applied all over your head. “It's great for gray coverage on brunettes,” Morales says.

Those who want highlights-ombre, foil, or balayage-but also need to cover grays, should opt for a two-step process. This can mean one all-over color and highlights, or all-over bleach and toner, which is often required to achieve platinum locks.

A protein treatment is applied to hair after your color is washed out, while you're still in the shampoo bowl. It's similar to a deep conditioner, because it strengthens hair without changing the color, but is much stronger. “A protein treatment helps with breakage if your hair is over-processed,” Morales says. “But you can only leave it on for a few minutes or it will damage your hair.”

Dying for straight hair? Morales suggests a keratin treatment, but don't forget to stick to sulfate-free shampoo and don't wash for four days after.
