Whether you're hoping to straighten and smooth ringlets or let them loose, finding the right shampoo is key to achieving your desired look. As a rule of thumb, Amanda Ambroise, hairstylist at Warren Tricomi in New York City, recommends seeking out a shampoo that replenishes moisture, since curly hair tends to be on the dryer side. Eden BodyWorks Coconut Shea Moisture Shampoo, $9.99, is her go-to for girls with curls.

Another top-recommended product is Kerastase Discipline Bain Fluidealiste Sulfate Free, $29.99, which is Bova's favorite. "The mixture of botanicals and argan stem cells encourage healthy hair growth," he says. "Argan oil also keeps the hair healthy and shiny, protecting the shaft from future damage."

If your hair is thinning, you're far from alone. In fact, according to statistics from the American Academy of Dermatology, 40 percent of women have visible hair loss by age 40. Thankfully, there are plenty of products on the market aimed specifically at diminishing shedding while thickening the hair follicles and strengthening strands to last longer than your next shower. Celebrity hairstylist Daniel Koye's go-to is Nioxin System 1 Cleanser Shampoo, $24.99. "This is a system that works well when used together to stimulate your scalp to grow more hair," he says. Ambroise's favorite is Viviscal Gorgeous Growth Densifying Shampoo, $9.99, which "combines biotin, keratin, zinc and more to promote healthy growing hair."

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.
