    5.0 out of 5 stars Great product
    Reviewed in the United States on January 7, 2025

    I use this product almost every time after I towel dry my hair. It has become an essential part of my hair care routine, providing me with the perfect balance of moisture and hold. If I’m planning on wearing my curls, which are of the 2C-3A hair type, I’ll pair this product with the ouai curl cream. Together, they leave my hair so smooth and frizz-free, enhancing the natural beauty of my curls. The combination is incredibly effective, and I often receive compliments on how defined and healthy my curls look.

    Sometimes, I’ll just use this product without the curl cream, and it works really well if I’m just straightening my hair as well. The product has a unique ability to smooth out my hair, reducing the need for excessive heat styling. It provides a sleek finish that lasts throughout the day, keeping my hair looking fresh and polished.

    Overall, it’s a very versatile product, and it’s a must-have in all of my hair routines. Whether I’m curling or straightening, it consistently delivers great results. I highly recommend this product to anyone looking to improve the quality and manageability of their hair. It’s a game-changer and has definitely earned its place in my beauty arsenal.

    5.0 out of 5 stars Works like magic
    Reviewed in the United States on May 12, 2024

    This stuff works surprisingly well!

    I tested it out by putting some on my dry hair on my ends and up toward my crown, focusing on areas with fly-aways. Then I followed it with straightening my hair with a flat iron.

    It made my hair significantly less frizzy and sleek looking.

    Once straightened the product seems to hold my hair in place—like giving it a new set-point. Instead of looking like wavy hair that’s been straightened my hair just looked like it’s naturally straight. I really love that.

    It took little effort with my straightener and less passes to straighten it.

    It’s now part of my regular routine and will likely stay that way unless they stop making it.

    My hair is down to my waist, thick but fine, and naturally wavy. My scalp can get oily easily with products, but I didn’t notice any difference in oiliness while using this.

    The smell is not very noticeable. It’s like a non-offensive, clean smell. It doesn’t compete with my perfume.

    The consistency is like a watery gel. It almost feels like hair gel when you put it on because you can feel it dry to the hair quickly. But it doesn’t make it feel stif, crunchy, sticky, oily or anything. It feels kinda perfect, like magic.

    It’s a cool product, I love it and recommend it!

    Wow! I have curly fine hair. Most things weigh it down and my curls go limp. Not this. All I use is half a pump of this and some curl cream and I have soft and shiny curls. I love it! It smells so good. It does not leave my hair sticky or greasy. I feel like this is helping with the health of my hair, shininess, and moisture. I believe it is worth the price.

    No frizz, super soft (like salon quality).

    I don’t like that my hands feel a little sticky/ gooey after applying.

    The truth the way.

    Smells great, makes my hair look amazing. So many applications. Heavy handed more sleek hair, just a little at the ends pulls down the frizz a bit. Adds that shine we all look for.

    Did I forget to mention I go from like a 2 TO A 9?!? I lift my hair all the way up to Gods hands. If I just use shampoo and conditioner my hair is dry and frizzy - which is cool some days but if I’m headed out to target just a couple of pumps of this added with that air dry and the looks hunny, double take. “Is that his real hair?” Has been said. So do with that what you will.

    I bleached my hair and went to cut the ends. I still have some hair remaining that was bleached so I really don’t want my ends to end up being so dry again. I’ve only used this twice and used one pump on my hair after towel drying it. And when I either air dry or blow dry it, it leaves my hair really soft and healthy. Love it!!
