If you heat style, start with Moroccanoil All in One Leave-in Conditioner. Moroccanoil says the spray detangles, hydrates and protects all hair types against breakage and thermal damage. The other four picks are better for a specific need: an all-in-one spray, a classic leave-in in big sizes, dry and frizzy hair, or Type 4 hair.

Every hair-type note, ingredient and claim below is the maker’s own. A leave-in goes on after washing and stays in, so it adds a step to your routine. Mielle and VERB say to apply theirs after shampoo and conditioner.

1. Moroccanoil All in One Leave-in Conditioner: Best for heat styling

Moroccanoil calls this a multitasking spray that detangles, hydrates and protects hair. It says the formula works on all hair types to protect against breakage and thermal damage, and nourishes and softens hair for up to 72 hours. The brand claims it reduces breakage by 49%, based on an independent lab study.

The lightweight, milky formula contains argan oil, amino acids that Moroccanoil says increase strength, a superfood blend of sunflower seed oil, quinoa and barley extracts, and naturally derived sugars. The ingredient list includes dimethicone and fragrance.

Spray it through clean, towel-dried hair, comb through, add your styling products and style as usual. Moroccanoil says you can also use it to refresh second-day hair. It comes in a 5.4 fl oz full size and a 1.7 fl oz travel size.

Those are the brand’s claims, and its page doesn’t give test data for them.

Key ingredients include sunflower seed extract, green tea leaf extract, silk amino acids, aloe vera and panthenol. The directions are to spray evenly from mid-shaft to ends on towel-dried hair, leave it in, comb through and style. It comes in 2 oz, 4 oz and 10 oz bottles.

The Amazon link opens the 10 oz bottle of the Miracle Leave-In Product.

3. Paul Mitchell The Conditioner: Best classic leave-in

After shampooing, apply a small amount to clean, damp hair and style as usual. It comes in the widest size range here: 2.5, 10.14, 16.9 and 33.8 fl oz. Paul Mitchell labels it cruelty-free, color-safe, vegan, paraben-free and made without gluten.

Best for: A simple daily leave-in for any hair type, or a large bottle for a household that shares one.

Skip it if: You need heat protection from the same product.

4. VERB Hydrate Leave-in Conditioner: Best for dry, frizzy hair

VERB makes Hydrate for dry, frizzy hair. It says the leave-in hydrates, reduces frizz and detangles for smooth hair. Key ingredients are argan oil, babassu oil and what VERB calls moisture-locking ceramides, which it says help smooth hair, add shine and increase elasticity.

Apply it to towel-dried hair on the mid-lengths and ends after shampoo and conditioner, then style as usual. It comes in a 6.5 fl oz bottle. VERB labels it paraben-free, gluten-free, free of harmful sulfates, PETA-certified cruelty-free and vegan.

5. Mielle Pomegranate & Honey Leave-In: Best for Type 4 hair

Mielle says it made this leave-in especially for Type 4 hair, as a moisturizing primer and detangler before styling. It also describes the formula as made for thick, curly hair. It is a lightweight formula with babassu oil, pomegranate, honey and citrus extracts, and Mielle says it smooths the cuticle to support curl definition and makes detangling easier.

Mielle says it is safe on chemically treated and color-treated hair. After washing and conditioning, apply a generous amount to sectioned, damp hair, work it from root to tip with a wide-tooth comb or your fingers, and don’t rinse. It comes in a 12 fl oz pump bottle, and the ingredient list includes fragrance. The Amazon link is a search, because Amazon’s listing is sold by a third-party seller rather than by Amazon or Mielle.

Best for: Type 4 coils and thick curls that need slip for detangling and moisture before styling.

Skip it if: Your hair is fine or straight, since Mielle made this for Type 4 and thick, curly hair.

How to choose a leave-in conditioner

Start with your hair type

Mielle makes its leave-in for Type 4 and thick, curly hair, and VERB makes Hydrate for dry, frizzy hair. Moroccanoil, It’s a 10 and Paul Mitchell say theirs suit all hair types. Whatever your type, follow the maker’s directions on amount and placement. Paul Mitchell says to use a small amount, It’s a 10 and VERB say to apply from the mid-lengths to the ends, and Mielle says to use a generous amount from root to tip.

Decide if it needs to protect against heat

Only two picks here make a heat claim. Moroccanoil says its leave-in protects against thermal damage, and It’s a 10 lists thermal protection among its benefits. If you use one of the others and style with heat, add a separate product. Our heat protectant spray picks compare each spray’s temperature claim.

Check the ingredient list for what you avoid

Moroccanoil’s list includes dimethicone, a silicone. Moroccanoil, It’s a 10 and Mielle all list fragrance. If you avoid either one, read the full list on the maker’s page before you buy.

Use it as an extra step

Mielle, VERB and Paul Mitchell all place their leave-in after washing, and Mielle and VERB after conditioner too. If your ends still feel dry, our hair mask picks are matched to hair type the same way.

FAQ

Do I still need regular conditioner if I use a leave-in?

Three of these makers tell you to use the leave-in after your regular routine. Mielle says to apply it after washing and conditioning, VERB after shampoo and conditioner, and Paul Mitchell after shampoo. So for those three, the leave-in is an added step after your usual routine.

Should leave-in conditioner go on wet or dry hair?

Every pick here goes on damp hair. It’s a 10, Moroccanoil and VERB say towel-dried hair, and Paul Mitchell and Mielle say damp hair. Moroccanoil also says its spray can refresh second-day hair.

Can a leave-in conditioner replace a heat protectant?
