For color-treated or highlighted hair, your primary concern is to protect your color and address any dryness or damage. In addition to using a moisturizing mask or conditioner, stylists recommend reaching for shampoos that help maintain the color and prolong the time between your next visit to the salon. For blondes, stylist Angela Kalinowski suggests Voce No Yellow Wash, $18. "It's great for canceling any yellow tint in the hair and is made with lavender, jasmine and natural proteins," she says. "It tones the color to a beautiful buttery blonde."

For blondes and all other hues, Bova's go-to is Bumble and Bumble Gentle Shampoo, $26. "This shampoo has gentle detergent that very gently cleanses and shines," he says. "Avocado oil and nettle extract leave the hair shiny without weighing it down."

Strands that are dry and brittle after years of heat styling and color processing are in dire need of serious moisture. According to Ambroise, the best shampoo for this hair type to really see a difference in texture and quality is Kerastase Bain Therapiste, $29.50. "This shampoo works to help repair weak, damaged hair and helps prevent damage before it starts."

Celebrity hairstylist Felix Fischer's favorite for hair in need of total repair is Amika Triple Rx Shampoo, $21. "The highly concentrated formula combines hydrolyzed keratin and hydrolyzed wheat protein for maximum penetration and repair," he says.

For platinum blondes and gray hair color, the goal is to maintain that icy, cool tone, says Ambroise. "Sometimes the hair will revert or start to change to a yellow color as the toner fades, due to contact with heat stylers, the sun or even washing," she says. She reaches for a classic shampoo, Clairol Shimmer Lights Shampoo, $12.50. "It's great for maintaining your cool tone because the shampoo itself is purple, which tones your hair with every wash."

There are plenty of other brands on the market that contain many of the same ingredients and work equally well, such as Davines Alchemic Shampoo Silver, $25.50, and Oribe Silverati Shampoo, $46, depending on your budget.

Whether you want your wavy hair to maintain its effortless texture or are looking for a sleeker style that's less voluminous, you can't go wrong with a shampoo that's m.o. is to control frizz. "For girls that rock their naturally wavy hair and want a controlled look, use Kerastase Discipline Bain Fluidealiste Sulfate Free, $29.99," says Ambroise. "It tames frizz, protects against humidity and disciplines the hair while providing a smooth, soft finish."

If you're hoping for even more definition and for that beachy, saltwater look, Bova suggests Bumble and Bumble Surf Foam Wash Shampoo, $26. "The mixture of sea minerals in this formula gives volume and wave definition and the botanical blend gives hydration and softness."

Even if you're committed to regular trims, long locks typically require a lot of work to keep them healthy and prevent breakage. That's why it's smart to stick with a moisturizing shampoo that contains hydrating ingredients to strengthen and restore, like Shea Moisture Jamaican Black Castor Oil Strengthen, Grow & Restore Shampoo, $12.99. "Castor oil is synonymous with hair growth and strength, as is vitamin-rich shea butter," says Bova. "The botanical blends keep the hair strong."

If your long locks tend to be on the oily side, especially around your scalp, but dry on the ends, Ambroise recommends a cleansing oil shampoo like Shu Uemura Cleansing Oil Gentle Radiance Cleanser, $42.50. "It draws out oil where oil is excessive and penetrates where oil is needed," she says.
