Deep Conditioners

Byrdie / Kevin Liang

We know that coloring, bleaching, processing, and heat styling can wreak havoc on your hair; but the right deep conditioner can help restore that damage, add moisture back into the hair, and leave it feeling soft and silky. Though using a deep conditioner is an extra step, it's one worth investing in since it can make a significant improvement in the look and feel of your hair.

To find the best options for a variety of hair types and hair concerns, we tapped celebrity hairstylist Sally Hershberger as well as pro stylist Michelle O’Connor to learn more about what to keep in mind when shopping for a deep conditioner. We evaluated each product based on ingredients, texture, feel on the hair, and overall results. We also took consumer reviews and our editor's personal experiences with these products into consideration when narrowing down our list.

Before jumping into our picks, here's what you'll want to consider when choosing the best deep conditioner for you:

  • Strengthening Properties: In addition to moisturizing benefits, O’Connor recommends reaching for a product that also has strengthening properties. She explains that lackluster hair in need of repair is usually experiencing some degree of breakage, and proteins and nourishing oils can help strengthen it. Keratin and argan oil are two great examples of fortifying ingredients to keep an eye out for.
  • Consistency: While you'll want your deep conditioner or hair mask to hydrate and strengthen your hair, you don’t want it to leave it oily or weighed down. Look for formulas that will ramp up hydration while still providing a lightweight finish sans any heavy or sticky residue. If your hair tends to get weighed down easily, we recommend opting for a mist.
  • Format: Ultimately, the best deep conditioner is one you'll actually use. While masks are great options for an in-shower treatment, those tight on time might prefer a leave-in formula. If you're big on everything showers, a rinse-out conditioner or luxurious mask might be right up your alley.

Best Overall

Olaplex No. 8 Moisture Mask

Olaplex No. 8 Bond Intense Moisture Mask

Sephora

What We Like
  • Creamy texture is easy to work into the hair

  • Features bond-building technology to help repair damage

  • Leaves hair feeling incredibly soft and smooth

What We Don't Like
  • Small bottle

Hair Type: All | Size: 3.3 oz | Cruelty-Free: Yes

Featuring the brand's unique bonding technology which relies on proteins to reduce breakage and restore broken hair bonds, as well as moisturizing glycerin, and a blend of nourishing oils, this mask strengthens and conditions damaged and dry hair. The texture and creamy but not too heavy, making it easy to work through wet hair, and we love that it's suitable for all hair types. For added fortifying benefits if you're experiencing serious damage, we recommend pairing it with the No. 3 Hair Repair Perfector, and editor-favorite weekly treatment. The one thing we don't love about this product is that you need a decent amount to coat your hair, so you'll likely run through the 3.3 oz bottle pretty fast.

Best Splurge

Christophe Robin Regenerating Mask

Christophe Robin Regenerating Mask

Amazon

What We Like
  • Adds moisture to hair

  • Helps smooth split ends

  • Enhances shine

What We Don't Like
  • Strong perfumey scent might be too intense for some

Hair Type: All, chemically treated | Size: 8.4 oz | Cruelty-Free: Yes

If you're willing to splurge on a high-end product that delivers salon-level results, consider Christophe Robin's Regenerating Mask with a blend of good-for-hair ingredients, like plant ceramides and prickly pear oil. Ceramides work to smooth the hair shaft while prickly pear oil helps hydrate and soften, thanks to its high concentration of vitamin E. The texture feels luxe and creamy, though it doesn't leave a residue behind. Over time, the mask works to repair existing damage and prevent new damage from occurring. Plus, it boosts the intensity of your hair color—something folks with color-treated hair will be especially happy about. Because leans heavily on prickly pear oil, it shouldn't come as a surprise that the pear fragrance is pretty potent. The scent is a bit strong and perfumey, so keep this in mind if you're sensitive to fragrance.

Best Budget

L’Oréal Elvive Total Repair 5 Damage-Erasing Balm

L’Oréal Paris Elvive Total Repair 5 Damage-Erasing Balm

Amazon

What We Like
  • Smooths damaged hair strands

  • Protein-rich

  • Creamy texture

What We Don't Like
  • May leave a residue

Hair Type: Dry and color-damaged | Size: 8.5 oz | Cruelty-Free: No

This multi-use formula from L'Oréal can be used as a co-wash, rinse-out mask, or leave-in treatment. We love how this deep conditioner treats split ends, brittle hair, and color damage with a blend of oils and proteins while detangling hair and leaving it ultra-smooth and shiny. Plus, it protects against heat styling up to 450 degrees. The only thing we aren't huge fans of is the fact that the formula can leave behind a residue if you're not careful to thoroughly wash it out.

Best for Damaged Hair

Kérastase Résistance Hair Mask

Kérastase Résistance Masque Therapiste Hair Mask

Sephora

What We Like
  • Pro-Keratine Complex repairs visible damage

  • Smoothing

What We Don't Like
  • Large amount needed each use

Hair Type: All, damaged | Size: 2.6 or 6.8 oz | Cruelty-Free: No

If your hair is visibly damaged due to bleaching or excessive heat-styling, Kérastase Resistance has your name on it. This deep-conditioning mask is chock full of protein-rich ingredients, including a Pro-Keratine Complex—a blend of protein and amino acids, like serine, arginine, and glutamic acid which help to strengthen the hair structure. It also contains ceramides that help moisturize, mend breakage, smooth hair follicles, and fortify brittle hair. Keep in mind that you may have to use a decent-sized amount of the mask each time to really work it through your hair, and considering that it's pricey, this isn't ideal.

Best Hydrating

Briogeo Don't Despair, Repair! Mask

Briogeo Don't Despair Repair Deep Conditioning Mask

Sephora

What We Like
  • Powered by vitamins and antioxidants

  • Helps reduce frizz

  • Available in four sizes

What We Don't Like
  • May take weeks to notice a difference

Hair Type: All | Size: 2, 8, 12, 32 fluid ounces | Cruelty-Free: Yes

Briogeo's take on deep conditioner is this transformative, ultra-hydrating mask that promises to strengthen stressed hair and protect it from future damage. It's a favorite among editors thanks to its ability to add moisture, smooth frizz, and strengthen the hair over time. It calls on amino acids, rosehip oil, and B vitamins to work its magic, and when used as a weekly treatment, it really does improve the look and feel of your hair. It has a creamy but lightweight texture that's easy to work into the hair, and we love that it's available in a variety of sizes. The only bone to pick: It takes a while to see results, but hang in there and be consistent—it's totally worth it.

Best Softening

Bread Beauty Supply Hair-Mask Creamy Deep Conditioner

Bread Beauty Supply Hair-Mask Creamy Deep Conditioner

Amazon

What We Like
  • Contains strengthening proteins

  • Softens and strengthens hair

  • Silicone-free which is great for hair that gets weighed down

What We Don't Like
  • Comes in a pouch which can be hard to use in the shower

Hair Type: Curly | Size: 12 oz | Cruelty-Free: Yes

Bread Hair-Mask was formulated with coily, curly, and wavy textures in mind, but all hair types can reap the benefits of this extra-creamy deep conditioner that leans on a potent blend of nutrient-rich oils—like starflower and Kakadu plum seed oils—and strengthening proteins. The formula is noticeably lightweight but doubles down on dry, damaged hair to soften, strengthen, and moisturize every last strand. It's also free from silicones which can be beneficial for fine strands or those who struggle with greasy or weighed-down hair. Our one con is that it's housed in a pouch that can get slippery when wet and deposit too much when it's squeezed too hard; just be careful while depositing the formula.

Best for Natural Hair

Pattern Intensive Conditioner

Pattern Intensive Conditioner

Target

What We Like
  • Contains a moisturizing blend of oils

  • Helps restore natural curl patterns

  • Nourishing for low porosity hair

  • Available in three sizes

What We Don't Like
  • Strong scent could be too intense for some

Hair Type: Curly and coily | Size: 3, 13, 29 oz | Cruelty-Free: Yes

Formulated to restore natural curl patterns and tight textures, the Pattern Intensive Conditioner is jam-packed with hydrating ingredients—like avocado oil and shea butter—to define, revive, and protect curls and coils. It was created specifically for low porosity hair, which often struggles to hold onto moisture. The texture is rich and creamy, and we love that it comes in multiple sizes, including a jumbo with a convenient pump.

Best for Curly Hair

Curls Dynasty Pumpkin Mint Deep Treatment Masque

Curls Dynasty Pumpkin Mint Deep Treatment Masque

Curls Dynasty

What We Like
  • Antioxidant-rich formula

  • Promotes hair growth

  • Adds definition to coils and curls

What We Don't Like
  • May be too heavy for fine hair

Hair Type: Curly | Size: 8 oz | Cruelty-Free: Yes

Curls Dynasty makes an indulgent deep conditioning mask that's packed with creamy pumpkin to fortify and rebuild a damaged hair shaft and promote new growth. We're big fans of the fact that this formula formula restores moisture at the cuticle level. The texture is rich and super-hydrating, making it a nice choice for those with curly hair that's damaged or lacking moisture. One thing to note: It's dense, so those with fine hair might find that it weighs hair down.

Best for Fine Hair

Virtue Flourish Conditioner for Thinning Hair

Virtue Flourish Conditioner for Thinning Hair

Sephora

What We Like
  • Lightweight enough to be used on scalp

  • Supports hair growth and thickening

  • Subtle aromatic scent

What We Don't Like
  • Not ideal for damaged hair

Hair Type: Fine | Size: 6.7 oz | Cruelty-Free: Yes

Those with fine hair know how challenging it can be to find a deep conditioner that supplies serious moisture without weighing your hair down or coating it in a greasy film. This one is great for fine and thinning hair because it's soft and creamy without being too rich. It's formulated with a protein complex that can help with hair growth and maintaining a healthy microbiome on the scalp. It also contains peptides for necessary moisture. It's not ideal for those with very damaged hair as it doesn't have bonding technology or a rich, smoothing formula, but it's great for those looking to condition fine hair and help encourage growth.

Best for Bleached Hair

Amika Bust Your Brass Cool Blonde Purple Intense Repair Hair Mask

Amika Bust Your Brass Cool Blonde Purple Intense Repair Hair Mask

Amazon

What We Like
  • Hydrating

  • Minimizes brassy tones

  • Contains bonding technology

What We Don't Like
  • Can stain hands and clothes

Hair Type: Color-treated | Size: 8 oz | Cruelty-Free: Yes

Whether you have highlights or a full-on platinum dye job, Bust Your Brass is great for moisturizing chemically lightened hair and neutralizing any brassy, orange hues. It features rich purple pigments to color-correct brass, as well as a bonding complex to help strengthen hair and target damage. Some reviewers note that if you leave the treatment on too long, the formula can turn hair purple, depending on porosity, so be sure to monitor appropriately. And because the treatment is so potent, it can stain skin and clothes. Remember to wash your hands after use and try not to get the treatment on clothes and towels. Overall, its brass-fighting, nourishing, and strengthening capabilities make it one worth checking out.

Best Leave-In

CHI Keratin Leave-In Conditioner

CHI Keratin Leave-In Conditioner

Amazon

What We Like
  • Contains keratin to repair and rebuild

  • Suitable for daily use

  • Lightweight spray formula

What We Don't Like
  • Strong perfumey scent

Hair Type: All | Size: 2, 6 oz | Cruelty-Free: Yes

CHI's Keratin Leave-In Conditioner is a lightweight no-rinse option that's great for applying right after washing your hair because it helps detangle, nourish, and strengthen every strand. We're big fans of the formula, which boasts a keratin-infused blend to repair the hair cuticle, improve elasticity, and protect against future breakage. It has a strong perfumey scent, which we don't love, so those who are sensitive to fragrance or perfumes might want to opt out of this one.

Best Detangling

LolaVie Glossing Detangler

LolaVie Glossing Detangler

LolaVie

What We Like
  • Doubles as a heat protectant

  • Adds a high-shine gloss

  • Lightweight mist

  • Available in three sizes

What We Don't Like
  • Can leave a residue if sprayed directly on roots of fine hair

Hair Type: All | Size: 2, 5, 12 oz | Cruelty-Free: Yes

Jennifer Aniston's haircare line LolaVie won't magically transform your hair into her signature 'do, but it's designed to garner excellent results for a variety of hair types and hair concerns. We love the Glossing Detangler—so much so that we named it a Byrdie Eco Beauty Award Winner—because it gently detangles hair without breaking it and doubles as a heat protectant. Lemon extract, chia seeds, and vegan ceramides make this fine leave-in spray formula a powerful conditioner that's lightweight enough to use as daily as a detangler for a high-gloss effect.

Best Bonding Mask

Vegamour Moisture Repair Mask

Vegamour HYDR-8 Deep Moisture Repair Mask

Sephora

What We Like
  • Helps reduce breakage

  • Reduces frizz

  • Adds moisture and shine

What We Don't Like
  • Not ideal for crown and scalp

Hair Type: All | Size: 5 oz | Cruelty-Free: Yes

This reparative hair mask from Vegamour is one you should have on your radar, especially if you have lots of flyaways and broken ends. It works to smooth, hydrate, and strengthen hair thanks to a formula powered by Karmatin, a vegan silk alternative to keratin and silicone. Unlike other bonding shampoos, Karmatin stays locked onto strands, bonding them together, rather than washing out with water. It also contains marula oil and moringa seed oil to boost moisture and shine. We love that it's so hydrating, but it can leave behind a bit of residue on the crown and scalp. So, for that reason, we recommend working the deep conditioner through just the lengths and ends of your hair instead.

Best Pre Blow-Dry Treatment

Redken Extreme Anti-Snap Treatment

Redken Anti-Snap Treatment

Amazon

What We Like
  • Lightweight spray

  • Protects hair against heat damage

  • Strengthens hair and minimizes breakage

What We Don't Like
  • Could be a bit more hydrating

Hair Type: All | Size: 8.5 oz | Cruelty-Free: No

We highly recommend applying a heat protectant or a nourishing leave-in conditioner before blow-drying your hair to minimize damage. This leave-in conditioner spray from Redken protects hair from heat damage by fortifying the hair cuticle and prevents hair from snapping by reducing friction and detangling. It has a lightweight, creamy texture that's easy to spritz and work into the hair, and we love that it helps reduce flyaways and frizz. We wish it contained more nourishing oils for added hydration benefits, but we love it for its strengthening and protecting benefits.

FAQ
  • Can you use a deep conditioner with regular conditioner?

    According to O’Connor, if your hair is very damaged, you can (and should) still use both a conditioner and a deep conditioner. She recommends applying a traditional conditioner as you normally would and then follow up with a deep conditioner as an extra reparative measure.

  • How long should you leave deep conditioner in your hair?

    How long you’ll need to keep your deep conditioner or conditioning mask on will vary from product to product, so be sure to read through any directions on the packaging thoroughly. However, O’Connor mentions that leaving a deep conditioner on for longer than recommended won’t harm your hair. “In fact, many people with curls and coils love to add time and elements of steam and heat to further enhance penetration,” she says. “This is especially key when you have low porosity hair.”

  • Are deep conditioners suited to all hair types?

    Yes, but you'll want to find the formula suited to your hair type. Celebrity hairstylist Sally Hershberger explains. "Finer hair can look flat and oily if you use deep treatments that are too heavy. Those with thicker and curlier hair will need a heavier formula to match their hair's porosity."
