I’ve always been really hard on my hair (obsessive brushing, frequent washing, constant blow drying and heat styling, you get the idea), and as a result, my hair was insanely dull and it felt dry and brittle. I tried everything to help reverse the damage and add much-needed moisture back into my strands, but nothing really made a difference…until I started using a deep conditioner.

They’re not the ~sexiest~ thing in my shower, but whatever—they make my hair look amazing. Why? Because deep conditioners contain a high concentration of moisturizing and hair-strengthening ingredients, like keratin, vitamin B5, and coconut oil, that penetrate your hair strand to help repair it and protect it from damage. And all it takes is one masking treatment to see a difference in softness, shine, and definition. So to help you find your perfect match, I’ve rounded up the 12 best deep conditioners that will give you the healthiest hair of your life.

Best Deep Conditioner for Color-Treated Hair

Olaplex No. 5 Bond Maintenance Conditioner


This bond-repairing deep conditioner can’t help you fix things with your ex, but it can repair damage in your hair from things like a bad bleach job or excessive hair coloring. The result? Shinier and healthier hair that has fresher, more vibrant color.


Best Deep Conditioner for Natural Hair

Briogeo Don’t Despair, Repair! Deep Conditioning Mask


Think of this deep conditioner as a tall glass of water for textured hair. It uses a blend of oils (like rosehip, avocado, argan, and almond) to give your strands an insane boost of hydration. Post-shampoo, massage the mask from roots to tips, leave it on for five minutes, and rinse.


Best Deep Conditioner for Flat Hair

Shu Uemura Muroto Volume Pure Lightness Treatment Mask


$31.00 (54% off)

You don’t need to be using a billion and one products to get the full, shiny hair of your dreams—trust me. This deep conditioner does it all at once. It contains a combo of volumizing ingredients plus sea water to both soften and hydrate your hair without weighing it down. 


Best Deep Conditioner for Dry Hair

The Mane Choice Heavenly Halo Deep Conditioner


This deep conditioner is the ultimate fix for dry hair. It’s formulated with hair-loving oils (hi, umutanga and palmarose oils) that hydrate dry hair and keep it moisturized. To get all of the smoothing benefits, rake the conditioner throughout your dry (yes, dry) hair and throw on a plastic cap. After an hour, rinse it out, and you’ll be good to go. 


Best Deep Conditioner for Split Ends

Ouai Treatment Masque


If your ends are nearing frayed-rope status, and you’re not ready for a haircut, reach for this deep conditioner. It’s formulated with artichoke leaf extract and tamarind seed extract, both of which help to lock in moisture and hide your split ends.


Best Single-Use Deep Conditioner

Pantene Pro-V Intense Rescue Shots Hair Ampoules


Infused with vitamin B5, lipids, and glycerin, this single-use deep conditioner is basically rehab for your hair. It coddles and minimizes everything from split ends to fried, dried sections of hair. But the best part? Each tube contains a single dose, so you know exactly how much you should be using.


Best Deep Conditioner for Over-Processed Hair

Kérastase Resistance Mask for Damaged Hair


We all have a friend who has a horror story about a chemical treatment gone wrong (hi, it’s me, I’m that friend) that leaves them with completely destroyed hair. But the best way to deal with the drama without chopping it all off? This deep conditioning treatment. It uses a combo of pro-keratin and ceramides to rebuild broken bonds along the hair shaft and smooth your ragged hair cuticle.


Best Deep Conditioner for Dry, Curly Hair

SheaMoisture Raw Shea Butter Deep Treatment Masque


Curly hair needs a ton of moisture, so your daily conditioner probably isn’t getting the job done on its own. Enter this ultra-hydrating deep conditioner. It’s formulated with shea butter, argan oil, and avocado oil to take your curls from dry and thirsty to moisturized, defined, and bouncy (and never overly greasy).


Best Deep Conditioner for Your Scalp

Head & Shoulders Royal Oils Deep Moisture Masque Conditioner


The MVP of this deep conditioner? Coconut oil. Not only does it make the formula smell amazing, but if you’ve got an itchy, flaky, or dry scalp, it’ll also help to soothe and moisturize it. Use your fingers to massage the formula into your hair and roots, then let it sit for about five minutes. Once you wash it out, your scalp will feel instant relief…and your dry-ass hair will look noticeably happier.


Best Deep Conditioner for Thick, Curly Hair

DevaCurl Melt Into Moisture Matcha Butter Conditioning Mask


Your thick, curly hair (#blessed) has finally met its moisturizing mask. This magic: hydrating ingredients like matcha butter, sweet almond oil, and beet root extract that transform your brittle, stiff hair into soft, defined curls.


Best Deep Conditioner for Flyaways

Aussie 3 Minute Miracle Smooth Deep Conditioner


Over your flyaways? This mask can smooth and minimize them thanks to aloe and sea kelp. Both ingredients help flyaways lie flat and protect your hair from the frizzing effects of humidity in less time than it’ll take to make your morning coffee (three mins, to be exact).


Best Deep Conditioner for Fine Hair

It’s A 10 Miracle Deep Conditioner


If you have fine hair, you probably have some issues with the idea of a “deep” conditioner. I mean, they promise softness and smoothness, but they can also make your feel stringy, limp, and greasy. Thankfully, this deep conditioner won’t weight down fine hair, thanks to a lightweight combo of hydrating glycerin and aloe leaf juice.
