I have been using this product for YEARS and will continue doing so. It’s very easy to use, smells nice and WORKS!!! I have frizzy, wavy hair and this helps tame the frizz so much. I spritz a couple of spritzes onto my hair when I get out of the shower and immediately notice a softness to my hair. I notice a big difference when I use this product in my hair after a shower - my hair feels so much more hydrated and moisturized. The detangling aspect also really does work. I use a wet brush and that paired with this spray does WONDERS to my hair when it’s fully dried. It appears more tamed and like I styled it when all I did was let my hair air dry. This is a longtime favorite of mine!

Recently started using chlorine water in my hair and it was shedding like there's no ending. My hair been braided because of my fear of combing it. I stopped using that water and still the shedding continued, then i bought this bad boy! I used it only once and that was it. Each time I undo a braid to see how much I would lose from that section. After using this leave in it really nipped my hair issue in the bud. I have yet to see the progress of my entire head of hair but I am sure it helped. The scent is fine no complaints and the quality is great. Definite value!

I was a little disappointed that the conditioner came open and leaking. I was giving this the benefit of the doubt even though there were lots of reviews about it arriving open and leaking. But I was hoping that wouldn’t be the case for me because people only tend to write reviews when something is wrong with the product or if they were even more satisfied with the product than they were expecting. Even though it arrived like that I still want to see it it’s worth the hassle of it arriving like that every time. The company should invest in a small plastic seal around the neck of the bottle that twists open, so that it can’t open and leak. Anyway I wasn’t angry, just a little disappointed. I’ll still be using the rest because it seems that it works good as a light weight, frizz control formula for what I currently need. Edit 1/3/25: So this formula does not work for frizz control at all. I have a mix of 3b and 3c curls and while my hair was soft, it didn’t control my hair the way I was hoping. My hair has grown longer so the curls are a little less defined because of the added weight. My normal leave in conditioner is heavy and heavy products lead to more stretched out curls. So I was hoping this lightweight leave in conditioner would be just what I needed. Just incase anyone is confused I do style my hair with leave in conditioner and flexible hold hair spray. With this conditioner it’s more like an add in and then you can add your normal products. I’m not going to lie though, I did 100% love it, and will continue to buy. Just didn’t work exactly how I hoped. This stuff though is like a weed grower for your hair cause I’ve been growing out my hair for 7 years already. I go for trims for the dead ends every 6 months to a year and I take my hair care very seriously, so it was sad for me that my hair only grew a few inches. But you also have to understand that I have a curl pattern, so in actuality when my hair is straight it’s like double the growth. But still I never straighten my hair and only count the growth for my curls since that’s how I always wear my hair. Anyway, with this ONE bottle, I have literally noticed hair growth!!! HAIR GROWTH! With CURLY hair!!! I literally went around telling everyone it was a Christmas miracle because how has this one bottle grown my hair faster than I have?! My hair literally grew like an inch or two which is crazy for when I pull my curls down until they’re straight to see JUST how long they are. Think about it like this. My hair when dry and styled is like 2-3 inches below my shoulders. Yet when I pull a curl down to show the shrinkage it goes down to my butt. Anyway, this has literally shown growth for my hair and will continue to buy! 9/10 for growth 7/10 for softness 7/10 for scent 1/10 for frizz control Ngl I do get people who sniff the air and be like, “What is that smell?!” And then they start sniffing closer to me and have literally straight up sniffed my hair before 😭 It seems quite a few people like the smell even if I think it’s mid.

The only time my husband comments on my hair is to tell me that it’s dry and needs to be trimmed but the first time I used this, my husband commented how soft my hair looks. If I need more after blow drying, I squirt it in wet hands and apply it to the dry ends. I loved it so much, I got a bottle sent to my daughter. She is trying to grow her hair out and absolutely LOVES this product!

I agree with many others about the scent -- I like it! Not too overpowering or fruity or sweet. I like the treatment for my wavy gray hair. I do caution you (as somebody else did--) to use a small amount to start, because a little too much and your hair might feel greasy. My hair tends to be oily naturally, so I use a tiny amount.

Recently bought this product and im in love!!! My hair is soo soft and frizz free. I have been looking for something like this and im so happy I purchased this. I used it before I blow dryed my hair and also air dryed on my wavy textured hair. Both times my hair looks fabulous. I will definitely be subscribing to this product.

My bottle did arrive open and the contents spilled out. But I did have some left to salvage..this product is great for the price and delivers. It helps detangle and condition my curls, as well as keeping the damage and split ends to a minimal which is helping the length of my hair tremendously! I pair it with the growth serum for the scalp!! Would definitely recommend both.

Smells amazing ! I bought this to use as a detangler on my grand daughter's hair. Is very thick, comes out in a stream if you spray it directly on the hair. I just spray my hands and rub it through her hair. After the bottle gets about half full, I fill it with water, then it will spray out good on her hair, or you could divide it between two bottles if you have them. Works great as a detangler and makes her hair super soft.

Ash NReviewed in Canada on March 9, 2024

I’ve been using this product for about a week and I’m absolutely in LOVE with it!! I colored and dyed my hair for years which caused lots of damage and hair loss. Last year I chopped all of my damaged hair off and I’ve been on a journey to grow it out long, strong and healthy. Now as stated on the bottle it won’t make a person grow more hair (I’ve been using Rosemary oil shampoo and a scalp massager for that which works very well) but it is designed to make hair stronger/better conditioned so that it won’t break. Right now the length of my hair is about halfway down my neck and I was noticing that a lot of the hairs were sticking out and feeling dry/full of static despite using conditioner in the shower. I live in Canada where the winter air is very drying and doesn’t help this problem either. I read up on leave in conditioners and this product had excellent reviews as well as a great price point (I paid $10 Canadian at the time of writing this review). These are my observations so far: - The spray nozzle can be a bit finicky/difficult to use as it’s kind of small. I find that spraying it in your hands then working it through the hair can make it easier to apply. It can feel a bit greasy on the hands but it washes off with no problem - I like to comb it through my hair using my hands and a hair brush to ensure even coverage from root to the ends. The brush glides through my hair and it never gets snagged on any knots - It smells wonderful! It smells stronger when first putting it on damp hair, but once your hair is dried I find that it isn’t as strong. I like this because I am sensitive to scents and get headaches if I smell a strong hair product all day - My hair is now very soft, silky and shiny. Theres no frizz anymore and my hair doesn’t feel heavy which I was worried about. It actually feels lighter and I can pass my fingers through my hair without them catching in any knots - I find it takes a little longer to dry my hair with the hair dryer, but it’s worth it because my hair doesn’t feel like straw anymore. I used my Revlon brush dryer which REALLY dries my hair out due to the high heat, and after using it to dry/style my hair it still felt soft, smooth and there were no split ends or frizz - If I let my hair air dry after using it I find it can look “greasy” but if you brush the hair out once it’s 100% dry it will look nice and shiny - I haven’t noticed any irritation to my scalp - You can really feel the conditioner in your hair when you shower the next day/the hair gets wet but I’m always able to wash it out with no issue after a good shampoo - I don’t notice any product being left on my pillow after sleeping with it in my hair. My hair also doesn’t have as many dents in it the next morning which is awesome because shorter hair tends to do this - It hasn’t caused any acne breakouts. I’m acne prone and was worried it would break me out if my hair that’s covered in this product came into contact with my skin, but so far there’s been no issue - I don’t notice any hair falling out in the shower or while brushing my hair out Overall I am very impressed with this product and the only thing I’m not a fan of is the spray nozzle. But as I mentioned before, if you spray it into your hands you can apply it more easily. I can’t wait to see how my hair looks as it continues to grow out!
