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...

The BEST leave in conditioner
Im a huuuuge fan of anything Olapex & this leave in conditioner is the bees knees lol My poor hair has been through way too much heat styling & bleaching lately so its just been looking super fried, brittle & honestly just awful. I LOVE a good leave in conditioner & this one works so well & makes my hair feel so soft & look so shiny without feeling or looking greasy. It smells amazing, easy to use & it doesn't weigh my hair down AT ALL. It actually makes my damaged ends feel so soft and silky instead of like straw(which is a literal nightmare iykyk). If your hair is like mine or even if you just want some extra hydration for your hair, you 100% need to add this to your collection ASAP!


Leaves My Hair Soft and Smooth
I really love this leave-in conditioner. It makes my hair feel soft, smooth, and much easier to manage without feeling heavy or greasy. My hair looks healthier and feels more moisturized after using it. A little goes a long way, and I would definitely buy it again.


Great for colored hair
I did received this product as part of an educational promotion to test and review. And this is my honest review I applied it all over the ends mostly , Bec my ends tend to be the driest and most porous part of my hair, so that's really what I paid attention to while trying this. I applied the OLAPLEX Leave-In Conditioner to my damp hair, focusing especially on my mid-lengths and ends. The product easily melted into my hair it didn't really have a smell , and doesn't feel sticky or like it weighed down my hair . After styling my hair, I was actually really impressed with how shiny and glossy it looked. What stood out to me the most was the difference in my ends. They looked much smoother and more polished instead of having that dry, porous appearance they normally have. My hair overall looks healthier and now has a really pretty shine without the ends looking rough so the dullness look I had is gone. I also like that this is something I can easily add into my normal hair routine without adding another complicated step. I am definitely going to continue using it, especially when my ends are feeling extra dry or need a little more moisture and smoothing.



Olaplex mini travel size no. 5
Let me start this review out by saying I'm giving it a five star compliment. This many travel size olaplex number 5 moisturize mend leave in conditioner is absolutely amazing. Example today I had my hair up for a few hours in a ponytail and I needed to get the ponytail marks out of my hair when I took it down I used this moisturize and mend conditioner and it helped style my hair the way that I liked and gave it such a fresh clean fragrance to it I would definitely recommend this olaplex number five.



Great product, clean packaging
Disclaimer: I received this product as part of an education promotion. While using it, I've realized that my coils have been visibly healthier and softer. I also recently had braids and to nourish my hair in the protective style, I would dilute the leave-in conditioner in a spray bottle and use it as a mist. This method was very effective, and kept my braids hydrated without it weighing down my hair. I also really like how small and portable the container is. It's so easy to drop it in my bag and use it throughout the day. Lastly, I like that the product comes in a pump, it makes using it really clean and easy. The only drawback for me is that I'm not the biggest fan of the scent. But overall I do recommend this product, it gets the job down and it's easy to use.
