Pros: Quickly detangles and protects the hair.
Cons: Strongly fragranced.
I love Ouai's Leave-In Conditioner because it's a lightweight spray that really fights my frizz and flyaways. I find it makes my hair ultra shiny, too. It also hydrates, detangles, and protects against heat.
Customer review: "This leave-in conditioner is awesome. I am leaving this review just after ordering my fourth bottle (a lot of OUAI's products have refill pouches for purchase, but this one does not). I have thick wavy hair that is pretty fine. This leave-in conditioner moisturizes, eliminates the frizz, and detangles my hair very easily, without weighing it down."

Pros: Lightweight and non-greasy, great for color-treated hair.
Cons: Glycolic acid may not be suitable for sensitive scalps.
This one from Living Proof has nourishing ingredients and glycolic acid to make your hair smoother and softer. It also blocks humidity.
Customer review: "This is the best leave-in conditioner I have ever tried! My color-treated hair tends to be frizzy, and this conditioner smoothed it out completely when I used the blow dryer. When I use the leave-in conditioner after washing my hair and just let my hair air-dry, my hair is full of volume but not frizzy. Highly recommend!"

Pros: Prevents frizziness, great for curly and coily hair types.
Cons: Strongly fragranced.
The consistency of this conditioner is on the thicker and creamier side. It works well on all hair types but is especially great for curly and wavy hair. Ingredients include lavender and rosemary leaf oils and nettle extract.
Customer review: "This has been life-changing for my hair. I use it at the end of wash day or during braid outs, and it always leaves my hair with a nice, healthy sheen and curl definition. Not to mention it smells really nice. The product also lasts a long time, even with regular use. Will definitely repurchase!"

Pros: Patented peptide technology works to repair damage from bleach, color, and other chemical services; restores strength to the hair.
Cons: Expensive.
This stylist-loved leave-in treatment from K18 uses patented peptide technology to reverse and repair damage done by bleach, color, or other chemical services like relaxing. It helps restore strength, bounce, and shine to otherwise dull strands.
Customer review: "I thought my hair was a lost cause, but K18 came to the rescue. If you want hair that makes you feel like a rock star every day, K18 is your backstage pass to hair heaven. It's like a hair rehab program, but way more fun. Love it."

Pros: Strengthening and softening, budget-friendly, includes nutrient-rich ingredients that deeply hydrate the hair.
Cons: Limited slip on some hair types.
This super-rich leave-in conditioner is so powerful at repairing, strengthening, and moisturizing hair. But you'll be happy to know it doesn't leave a greasy finish or residue. Ingredients include raw shea butter, black castor oil, peppermint, and omegas.
Customer review: "I have been using this for about five years now, and I still love it! I have frizzy, curly hair that tangles very easily. After my shampoo, I use this as my leave-in conditioner, and it makes my hair easy to comb through. This is absolutely all my hair needs to keep it controlled all day without the frizz. It is not heavy or oily but just perfect for my hair."

Pros: Prevents knots and breakage, great for curly and coily hair types.
Cons: None.

Pros: Keeps hair looking and feeling smooth, eliminates flyaways and frizz.
Cons: Strongly fragranced.
As this conditioner's name suggests, you'll say goodbye to frizz if you try this. Rose-hip oil in the formula protects hair from radical damage and reduces frizz, while argan oil conditions and coconut oil locks in moisture. It's good for both straight and curly hair types.
Customer review: "This is my third bottle. I have a mix of wavy and straight bleached hair. This is the only one that tames my hair. I use it right after I shower. Doesn't make my hair greasy or weigh it down. Smells fresh. Little goes a long way."

Pros: Good for all hair types, detangles, infused with emollient oils to deeply hydrate.
Cons: Semi-runny formula.
While it's best to use this conditioner on damp hair, you can still use it on dry hair to give it a little more oomph or to restyle. The lightweight formula detangles and moisturizes.
Customer review: "This lightweight spray is really nice for dry climates. It gives my hair a healthy-looking shine and feels really nice. Do make sure to shake the bottle hard! And I only use one pump. If I use more, my hair starts to get greasy. I use this on wet and dry hair, and it leaves me soft and shiny."

Pros: Defines and softens curls, detangles, hydrates.
Cons: Semi-greasy finish on certain hair types.
Another option for curly hair types, this one not only strengthens and softens hair but also adds shine. The lotion-like formula contains nourishing ingredients like sunflower-seed extract, coconut oil, and shea butter.

Pros: Formulated with clean ingredients, detangles and prevents breakage, contains ingredients that shield against UV damage.
Cons: Not moisturizing enough for tighter curl types.
The cool thing about this treatment is that it has UV protection thanks to oil made from an Amazonian fruit rich in vitamins and antioxidants. It also detangles and prevents breakage.
Customer review: "I use this product as a compliment to their shampoo and conditioner, alongside the Reverie Milk, and love it! Since switching to clean hair care, I found I needed all the extra moisture to prevent dry extra frizzy hair. This product helps!"

Pros: Ultra moisturizing, provides body and definition to curls.
Cons: May weigh down hair.
If your curls need moisture and volume, this curl-plumping primer and gelée can help. It can act as a base "primer" for any other gel products you might want to use to give your curls definition and hydration.
