I'm not sure who's area it falls under but the bottle was only 1/2 full when it arrived, it was not all over the plastic and the bottle wasn't sticky like it leaked. As soon as I picked it up I could tell it was 1/2 empty. Asked for a refund because it was expensive, $13 for 8 oz. They will refund the money if you pack it up and take it to the post office or schedule a FedEx pick up.

Amazing! Works really great for fine hair, makes it more fluid and easier to move, not sticking and snarling and pulling out in clumps! Got this for my kids because their hair is so so fine but they have a ton of hair!!

Highly recommended!!

I expected more.
18 July 2022

For this price the truth is that I expected more surprising results. I don't notice any positive difference between using it and not using it, I think my hair looks better if I don't use it, and that's why right now it's collecting dust in a drawer.Keep in mind that my hair is bleached and colored, but despite that it is very healthy.I think the problem is that this product contains protein and my hair is low porosity, so protein just doesn't do my hair any good and makes it look worse. If your hair is high porosity (if you stick a hair strand in a glass of water and your hair sinks) then this product might be worth it for you.

Made my hair crunchy
10 October 2023

I recently purchased a leave-in hair conditioner spray with high hopes of achieving soft, manageable hair. Unfortunately, my experience with this product has been far from satisfactory. Instead of delivering the promised nourishment and moisture, it has left my hair feeling dry, tangled, and unexpectedly crunchy.Upon first application, I noticed that the spray had a pleasant scent and a lightweight texture, which made it easy to distribute throughout my hair. However, as it dried, I could feel my hair becoming increasingly stiff and difficult to pass through with my hands or a comb.

Unfortunately, my experience with this product has been far from satisfactory. Instead of delivering the promised nourishment and moisture, it has left my hair feeling dry, tangled, and unexpectedly crunchy.Upon first application, I noticed that the spray had a pleasant scent and a lightweight texture, which made it easy to distribute throughout my hair. However, as it dried, I could feel my hair becoming increasingly stiff and difficult to pass through with my hands or a comb. The product's inability to provide the desired hydration has been a major letdown.Additionally, I was disappointed by the lack of long-lasting effects. Despite following the instructions and using the spray on damp hair, my hair's dry and crunchy texture persisted throughout the day. The promised softness and smoothness were nowhere to be found, resulting in a less-than-desirable appearance and a constant battle with frizz.I cannot recommend this leave-in hair conditioner spray. Its inability to provide the necessary moisture and leaving my hair feeling dry and crunchy makes it unsuitable for anyone seeking a reliable solution to improve hair texture. I will be seeking an alternative product that can deliver the promised results and restore my hair's health and vitality.

avarage quality product, smells good. good size.packaged well.be very generous when sprying to cover all your hair. a little doesn't go a long way.helps reduce the frizz.I always combine it with another moisturizer, as it doesn't do the job alone

Smells great and adds shine
5 November 2023

It's basically just a leave-in conditioner, nothing fancy. Don't expect a miracle as far as hair repair goes though. I found I only had to spray a moderate amount. Using too much makes my hair feel greasy. Also, I found it was better to use a conditioner that I rinse out before applying this. When I used this on its own, my hair was too tangly.

good stuff if you ever get it
3 September 2023

I've ordered this twice. first time it came without a cap and only 4 oz of product, the rest had leaked out all over the place. I took it to Walmart for a refund and they said they couldn't do it!I order the second one because I like the product. The second one was an empty envelope with no product at all, just an envelope! tried to contact them for a refund / replacement and all they want is a return. really? You want me to return an empty envelope? I want my money back! for both of them!!!

I haven’t noticed any smell. I don’t like how crispy and hard it makes my hair after just a few sprays on damp hair. I tried it again to spray it throughout my hair and rinse it off completely. It turns out way better than spraying it on and leave it to dry. I’ll be doing it this way though the whole bottle.
