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.
Olaplex's Hair Perfector No. 3 ($28) is a cult-loved must-have for anyone who routinely color-treats their hair. When the brand debuted a complimentary shampoo and conditioner last year, pandemonium (and healthier hair everywhere) basically ensued. It's formulated without the icky things like sulfates and parabens and boasts a concentrated treatment profile that helps reduce and prevent breakage.
A best-selling cleansing option for every single hair type, Sephora shoppers go agog for this unique detoxifying blend of charcoal and coconut oil which helps exfoliate, soothe, and re-balance an irritated or flake-prone scalp. (This is an especially great pick to nab in preparation for a sweaty, sun-soaked summer!)
The main reason we love and use conditioner is to ensure our strands stay ultra-shiny and dehydrated post-shampooing. And according to Sephora sales, this moisturizing hair conditioner from Alterna is the very best at making all hair types look revitalized after a wash. It's infused with luxe caviar in addition to other hair-healthy nutrients like omega-3 fatty acids, proteins, and minerals A, C, and D.
Yep, Sephora shoppers have good taste because this hair-perfecting dry shampoo is a holy-grail formula in the eyes of beauty editors too. Regardless of whether you have thick, medium, or fine texture, it effortlessly sops up excess oil and leaves hair clean, bouncy, and refreshed.
We love this dry shampoo for its signature Drybar scent (think notes of jasmine, Madagascar vanilla, and sandalwood), but it's also one of the best for making our hair look like it's on day two or three, not four or five.
If you have curly hair and are looking for a top-notch zero-lather co-wash, you've officially met your new great-hair-day BFF. This original formula from DevaCurl blesses parched strands with a needed surge of moisture without weighing down curls or natural volume. Plus, it yields an insane amount of shine.
Briogeo Be Gentle, Be Kind Avocado + Quinoa Co-Wash
The superfood roster of ingredients in this co-wash instantly helps detangle hair curly, natural hair while also imparting shine and moisture. Oh, and if you happen to color your hair, it will help extend your time in between appointments as it will never strip away your color.
This holy-grail leave-in conditioner from Ouai is the ultimate multitasking answer to pretty much every kind of hair woe. From thermal protection to frizz control to shine and conditioning, just a few spritzes of this formula on damp hair works wonders.
It's safe to say Sephora customers go wild for Briogeo, and since the brand is also a personal favorite of ours, we definitely don't blame them. This milk-infused concoction saves starved strands before you air or blow dry and ensures hair is left soft, shiny, smooth, and protected from potential environmental threats like pollution or sun exposure.
So here's a fun fact, the top three best-selling hairsprays at Sephora are all from Living Proof. (This one is closely followed by the brand's Control Hairspray $26 and then the Perfect Hair Day Body Builder $29—my personal favorite.)
In second (non–Living Proof) place? This deliciously scented best seller from Moroccanoil. It's strategically infused with the brand's signature hero ingredient, argan oil, so hair not only stays in place but is also gifted with a veil of stunning shine.
This is probably the most iconic hair oil on the market, and we doubt any hair serum or oil will ever dethrone it. It's great for all hair types, can be used on dry or damp hair alike, and even helps decrease blow-dry time. And, obviously, it makes your hair shine like a beacon.
This multi-tasking organic argan oil from Josie Maran is the ultimate antidote for thirsty, split strands. That said, you can also use it on your face, cuticles, elbows, or really anywhere that needs a little TLC.
Featuring Living Proof's signature healthy hair molecule (aka OFPMA, which increases the spreadability on the hair), this easy-to-use styler primes either dry or damp hair for styling, hold, and superior manageability. We especially love to work it through our damp strands before a blowout.
I can say from personal experience that this brand new shimmering mist from Briogeo is well-worth the hype. I used it during Coachella and it not only kept my strands hydrated, soft, and bouncy but also dusted with a hint of shimmer and sheen that was super photogenic and flattering. (I sprayed myself with the stuff from head to toe!)
Briogeo Don't Despair, Repair! Deep Conditioning Mask
Designed to be used roughly once per week (give or take how often you wash your hair), this intense treatment rejuvenates hair with needed moisture while also arming weak and brittle strands with an extra dose of fortification and strength. Hair will look hydrated, color will be vibrant, and the potential for future damage will be decreased.
Calling all blondes, this best-selling hair mask is for you! We don't see purple formulas make the best-seller lists often just because they're often drying and all-around not great, but this new debut from Kérastase has us eating our words. This mask is an investment at $59, but the expert blend of color-correcting ultra-violet neutralizers, hyaluronic acid, and antioxidant-rich edelweiss flower is well worth your money.
Brand new from The Ordinary, this scalp-reviving treatment is a savvy solution for anyone with dryness, flakes, or irritation at the scalp. The concentrated formulation works well for all skin types and has a unique blend of ingredients to target stem cells (for increased hair density) while also improving blood flow and circulation for overall healthier hair.
Christophe Robin Cleansing Purifying Scrub with Sea Salt
This salt scrub from Christophe Robin has had a cult following for years, and it's still a best-selling favorite among Sephora shoppers. In addition to its soothing properties (it basically feels like a tall drink of water for your head), it also helps detoxify and purify the hair follicles so hair can grow in fast, strong, and ultra-healthy.
If you could ensure your strands a perfect hair day for the rest of eternity would you spend upward of $500? Apparently, a number of Sephora shoppers would. In fact, this epic styling bundle from Dyson is so popular, it's almost always out of stock. Highlights include no extreme heat damage, inclusivity for all hair types and textures, and endless options for styling and finish including curls, waves, or impeccably smooth volume.
GHD is known within the industry as one of the very best brands where styling tools are concerned and this flat iron is a favorite among Sephora customers and celebrity stylists alike. It features a ground-breaking technology that actually predicts your hair's needs to help your flat iron adapt its temperature for all of your strands' styling needs. You'll end up with less breakage but more shine and color protection.
Once again, Sephora shoppers prove they value quality, even if it costs them a pretty penny. This hair dryer is the best of the best, and in addition to being lightweight, it also features a high-speed digital motor for significantly faster dry time and smart heat control to aid both shine and styling protection.
