10 Best Leave-in Conditioners That Make Dry, Dull Hair Look Instantly Healthier

“I use this product out of the shower focusing on my ends and roots! I typically like to apply it messily because it gives me that effortless, touseled look I love. The lightweight texture never leaves my hair feeling crunchy or stiff. It absorbs easily and keeps my hair soft and touchable. I also appreciate that I can use it before heat styling for added protection, something I don’t always get with other leave-in conditioners. It gives me moisture and heat protection in one step, which makes my routine so much easier.” —Bianca Richards, social media manager

“I was bald until about age two, at which time my scalp sprouted a small handful of the most delicate, baby-fine (no pun intended) strands known to mankind. All that to say, I've been personally vetting the best products for fine, straight hair for most of my life, and I can confidently say that Crown Affair The Leave-In Conditioner is one of the few leave-ins that doesn't drag me down. I rake a dime-size dollop through damp mid-lengths and ends, then blow-dry and delight in how healthy and hydrated my hair feels.” —Dianna Singh, features director

“It was love at first spritz for me with the Davines Love Smoothing Perfector. I have extremely dry, frizzy, and heat-damaged hair that needs daily TLC, and this leave-in spray delivers! For anyone whose hair responds better to finer mist sprays than leave-in creams or even serums, this could be the product for you. I love the lavender formula, not that it truly matters, but it's very pretty on my counter and to the eye.

Because the mist—which smells heavenly by the way, and generally lighter in fragrance than other Davines products that are a bit too strong for me—is made up of finer particles, I think it penetrates my hair more effectively to really tamp down the stubborn frizz. It's an essential step to my curl routine, lest I want to look like a tumbleweed. The pump top will sometimes not work—I'll need to give it a little break and return to it or pump it a few extra times to reload. It can be frustrating, especially when you're in a hurry, so sometimes I'll just pop the bottle open and apply it by hand to my hair before diffusing.”—Shanna Shipin, senior commerce director

“Leave-in conditioner is nonnegotiable for my dry, frizzy hair, but especially when it's been bleached and color-treated (like it is now). I truly think this Moroccanoil spritz does it all—it detangles, smooths, and makes my hair look much healthier and bouncier post blow-dry. Instead of the usual brittleness I feel when I run my fingers through my hair, it's just silky sailing down to my ends. I spray very liberally, thoroughly rake through my hair to disperse the product as evenly as I can, let it sit for a few minutes, and then hit it with the dryer. After all that’s said and done, there’s very little frizz to be seen.” —Sarah Han, commerce editor

• Key ingredients: argan oil, superfood blend (sunflower seed oil, quinoa extract, and barley extract), pure amino acids
• Who it's for: fine to medium hair
• Fragrance-free: no

“Two or three quarter-size dollops of this emollient lotion help smooth my frizz and define my waves. I dispense it onto my hands, massage it into my poofy waves (dry or wet), and loosely tie my hair into a loose, low bun. Whenever I release it, it looks way smoother—staying that way for the rest of the day. It smells amazing, too. I get comments like, ‘What fragrance are you wearing?’ on the woody, clean scent whenever I wear my hair down.” —Jesa Marie Calaor, senior editor

“I was initially confused by the ‘sealing lotion’ title, but this leave in from Cécred does seal in all the moisture before I move on to the next step. My hairstylist has been explaining how dry hair is more prone to breakage, begging me to stop letting my hair air dry without any product. So now I use this leave in before I blow dry my hair. It doesn't have any heat protectant, but it makes my hair feel silky and adds shine. It's not so thick that it leaves a residue behind. After my hair is stretched, I apply a bit more before putting in my styling cream.”—Jessica Cruel, editor in chief

• Key ingredients: glycerin, shea butter, olive oil
• Who it’s for: thick, frizzy, and curly hair
• Fragrance-free: no

“I'm a firm believer that a post-shower hair routine is not finished unless you have applied a detangler, leave-in, hair oil, and heat protector (my hair can handle all the product without getting greasy; fair warning that yours might not!). I'm constantly cycling through products and testing new things, but this new leave-in is quickly gaining a spot in my favorites list. It's super easy to use—just a couple of pumps run through hair with your fingers. Though it does say to wait four to five minutes before applying other products, I'm impatient or in a rush, and usually wait just a minute or two.

I find it gives my natural waves a little more structure, especially if I put my hair into a bun or a braid as it dries (which I did for the photo you see above). I'm also both a sucker for the Nécessaire’s sleek and minimalist packaging, and this mask's fresh rosemary scent.” —Alessandra Foresto, managing editor

• Key ingredients: 5% vegan keratin, rosemary oil, rosemary extract
• Who it’s for: dry, split, and frayed hair in need of a pick-me-up
• Fragrance-free: no

“Out of all of the products I tested for the 2025 Best of Beauty Awards, this deliciously scented leave-in is the one I’ve restocked the most. It’s creamy but lightweight, and makes my bright blonde strands feel more like silk than straw." —Sarah Kinonen, beauty director

• Key ingredients: oat, almond, coconut milk, lemon juice, extra virgin olive oil

• Fragrance-free: no

“Did the coconut scent (the brand's St. Barts) cause a debate around Allure HQ? Maybe. But this leave-in did a bang-up job of controlling my frizz amid a humid week, and made my hair feel so much softer despite my daily washing. (Also: I liked the beachy scent!) I also love that it contains heat protection, so I can spritz it in before diffusing my hair and know that I'm covered.” —Deanna Pai, contributing commerce editor

• Key ingredients: tamarind seed, vitamin E, panthenol, hydrolyzed proteins
• Who it's for: all hair types
• Fragrance-free: no

“I've been using this product for nearly 10 years. I'm a huge fan of the Curls brand, specifically their Blueberry Bliss shampoo and conditioner. So it naturally makes sense that I use their Leave-In too. I use around five quarter-sized dollops for my entire head. The leave-in is super thick—and my hair absorbs product quickly (hello, high porosity)—so a little goes a long way. So, this leave-in bottle can last for nearly 3 months. The scent is nice, but can be overwhelming especially for those with fragrance sensitivities. So, I wouldn't recommend you use this if you prefer fragrance-free products. When I use it, I don't need to rehydrate my coils for another four days, which is great for a low-maintenance natural hair girl like myself. And I love how I can use this product on all my wigs, not just my natural hair!”—Melanie Curry, associate manager of audience development

"Leave-ins are tricky for my fine, bleached hair: I need moisture to help deal with the chemical damage, but not too much that it weighs my strands down. Ceremonia hits that balance perfectly; the Guava leave-in makes my hair so soft and shiny."—Kara McGrath, content director
