When it comes to hair care, finding the perfect product for wavy and curly hair can feel like discovering a rare gem.

Most Helpful Critical Review
It's ok but there's better ones out there.
I had high hopes for this leave-in conditioner, especially with all the promises of multi-level repair, hydration, and split-end mending. And while it does deliver on a few things, I'm honestly left feeling a little underwhelmed for the price and hype. First, the good: It definitely made my hair fe...

Hair Type Straight Hair
My hair tends to get dry and a little frizzy on the ends, especially after heat styling, and most leave-ins either coat it too much or disappear completely. This one somehow manages to smooth, hydrate, and still keep my hair feeling light and clean. This product was provided for promotional purposes in exchange for my honest review*


Must-have for frizz
An Olaplex fan, but this is my new fave. A small amount applied to mid-length to ends, is perfect for airdried waves. It softens, defrizzes and adds shine. A quarter size left my hair feeling a bit greasy, but a dime size is perfect.
Silky and shiny!
Hair Type Straight Hair
This leave in helps a lot with keeping my straight hair more sleek and shiny. I don't use heat on my hair, so it doesn't always look the best after air drying. I noticed that after putting this on, my hair dried straighter and less frizzy. It's also a great option for a conditioner replacement if you don't have access to one! I went to the beach with friends, and we only had a bottle of shampoo at the Airbnb we stayed in; however, after showering and using the shampoo, we all put it on our hair to see if it would make up for the lack of conditioner, and it did! My hair has been looking so much healthier, especially the ends. I only put 4 stars because it isn't the most life-changing product, but it's very good and I love using it!

Leave in Conditioner
Hair Type Straight Hair
My name is Jen, I am a mom of 3 wild boys. This is my way of doing something for myself and being girlie. I had the privilege of being able to try out the Olaplex- No.5L Moisturize & Mend Leave-In Conditioner. The leave-in conditioner makes your hair feel healthier after one use. If you have issues with split ins like I do, you will see an improvement in those as well. I felt like it gave my hair some hydration and didn't leave my hair feeling oily afterwards. I feel like this product works for my fine/thin hair. I haven't used it as much as I would want to before submitting my review as I am a busy mom of 3 boys/summertime. But defn will try and use it more now that some things are slowing down. This product was provided for promotional purposes in exchange for my honest review.


Not For Me
I was really excited to try this given the positive ratings, but unfortunately it did not agree with my hair. I have medium/fine color-treated hair, I tried it several times both damp and dry and unfortunately it made my hair extremely frizzy and corse-feeling. Definitely bummed.
