The 23 Most Sought-After Hair Products You Can Buy At Sephora Right Now

Unlike Sephora's vast collection of best-selling makeup and skincare products, hair products are a little bit trickier to shop for. We can't simply turn our forearm into a palette of swatched shampoos or rub 50 different hair oils over every square inch of our hands like we can lipsticks or face creams. So every time we decide to bite the bullet and turn over our hard-earned cash in exchange for a boatload of new hair formulas, it's always a bit of a toss-up whether or not we'll actually love what we ultimately cherry-picked from the retailer's stock-stuffed shelves. 

That said, there is a strategic way to cheat the system, or at the very least, improve our odds of loving (not simply putting up with) a selection of new hair picks—perusing the best-sellers list. Sephora shoppers are a passionate crowd, so whenever we see that a product with thousands of loves, ratings, and filled-out stars has ranked top tier for number of items sold, we're basically sold right off the bat. So you don't even have to bother to do the research and work yourself, we went ahead and found the two best-selling hair products from every single category your strands and styling MO desire. Keep scrolling for our holy-grail list of the 23 best-selling hair products Sephora customers are obsessed with spending their money on.

Beauty Director

Erin has been writing a mix of beauty and wellness content for Who What Wear for over four years. Prior to that, she spent two and half years writing for Byrdie. She now calls Santa Monica home but grew up in Minnetonka, Minnesota, and studied writing, rhetoric, and communication at University of Wisconsin, La Crosse. She studied abroad in Galway, Ireland, and spent a summer in L.A. interning with the Byrdie and Who What Wear family. After graduating from UW, she spent one year in San Francisco, where she worked as a writer for Pottery Barn Kids and PBteen before moving down to L.A. to begin her career as a beauty editor. She considers her day-to-day beauty aesthetic very low-maintenance and relies on staples like clear brow serum (from Kimiko!), Lawless's Lip Plumping Mask in Cherry Vanilla, and an eyelash curler. For special occasions or days when she's taking more meetings or has an event, she'll wear anything and everything from Charlotte Tilbury (the foundations are game-changing), some shimmer on her lids (Stila and Róen do it best), and a few coats of the best mascara-type product on earth, Surratt's Noir Lash Tint.
