Please, please do not wash out your fresh balayage coloring by using a shampoo formulated with sulfates. This gentle cleanser from Grown Alchemist promises to keep color intact, while saving you a much-too-soon trip to the salon to fix your faded dye job. Plus, this bottle is exactly what every modern aesthete needs in her bathroom.

Kristin Ess, the stylist responsible for Lauren Conrad's beach waves and Lucy Hale's lob, has (finally) joined the ranks of celebrity stylists with namesake hair-care lines. Ess knows the importance of a sulfate-free shampoo, and that's why she made it available to the masses with this $10 steal, on shelves at Target.

Have you ever seen Khloe Kardashian with a flyaway? Credit her sleek waves to stylist Jen Atkin, who launched her own brand so the rest of us can keep up. The best sulfate-free shampoos aren't just about protecting color; this one manages to tame frizz while giving a gentle cleanse.

You don't often hear about cult classic shampoos, but Living Proof's Perfect Hair Day (PhD to those in the know) makes the list. It's safe for all hair types, affordable and gentle enough to use daily.

You can't age out of protecting your hair. With more women choosing to keep their hair a natural gray -- and the trendier among us dyeing it silver before it has a chance to get there -- it's no surprise that a brand created a shampoo specifically for silver hair. This formula softens the coarseness that can come with aging hair and neutralizes yellow tones, leaving you with pure silver hair.
