Protecting your color from enemy number one, the sun, can be tricky. But there's a range of products out there that shield and preserve the pigment. Look for ones with UV protectant built in.
"They're in shampoos, conditioners," said Ellen Miller, of Shape Magazine.
When it comes to your roots, there are certain touch-up products to reach for. Using either an angled brush or small wands, it's a way to put off that expensive salon touch up.
"The more permanent options have a much wider variety of colors, while the temporary ones are less so, five or six shades," Miller said.
At Tela Salon, Philip Pelusi mixes up concoctions that mimic salon treatments. He uses raw ingredients, like sugar and olive oil (a natural exfoliate), oatmeal, and bananas for body. Tea of all kinds will leave your locks shiny and give it a hint of color - chamomile for blonds, key largo for brunettes.
He suggests using a blender to whip up the at-home remedies.
"You want a creamy-type texture, not too runny," he said. "A good guide is to start with 50/50 and always add or take away some."
