If you're going to pay a pretty penny for the prettiest hair color a bottle can give you, my guess is that you want it to last as long as possible - and I'm not talking about the regrowth that reveals your contrasting roots. That's inevitable, unfortunately. But equally as unfortunate is the fact that the best of summer activities (i.e.: sunbathing and swimming) can cause colored hair to fade and lose its vibrancy and shine.

So, whether it’s natural or store-bought, here are a few tips and products to maintain the boldness of your blonde, brunette or rockin’ red locks.

First off, it’s a good idea to regularly use shampoo and conditioner that’s formulated for color treated hair. Shampoo for colored hair might lather less, but, trust me, it’s still doing the job.

Then, take it one step further and search out a color-depositing product that you can use once a week. It’ll extend the life of your color even more.

And as always, protect your hair before swimming, especially in chlorinated pools, and especially if you're a blonde. Wet your hair with clean water first, and then apply a leave-in conditioner. You should also avoid using clarifying shampoos on color treated hair, as their purpose is to give the hair a really good scrubbing, which isn’t fab for color that’s not natural.

BLONDE/PLATINUM/WHITE

Tone brassiness and yellowing in blonde, platinum and white hair with a deep purple shampoo. The deeper and more opaque the purple, the better - light purple products won't do the trick. And if you're worried about ending up with purple hair, don't. Purple is the color across from yellow on the color wheel, which means all it does is counteract.

Protect your hair from going green at the pool by spraying on a leave-in conditioner pre-swim. Wet hair with clean water first, comb it through, and you're good to go.

BRUNETTE

If it's Kate Middleton's incredible shine you're after, maintain your own hair's vibrancy with John Frieda's Brilliant Brunette collection. It's formulated with crushed pearls and sweet almond oil, so it moisturizes, replenishes and preserves color.

REDHEAD

Pureology Reviving Red Shampoo and Red Reflect Enhancer, Classy Chassis

If you're not blessed as a natural ginger, this is arguably the toughest color to maintain, as it fades fast. Stay on top of it by shampooing and conditioning with a red-specific formula, and then once a week apply a color depositing treatment like Pureology's Red Reflect Enhancer.
