Serum Spray - Leave-In Anti-Frizz Hair Serum 4oz | Weightless leave-in serum that smooths frizz, defines curls, and adds natural shine.

I decided to write this review after reading insane low reviews. Ignore. How anyone finds this smell offensive is beyond my logical comprehension? The smell is soft and neutral all natural smells. Amazing Heat Protector! Salon quality that leaves Aveda in the dust. So far superior to anything I bought from Aveda. My hair is soft and luxurious after my blow dry, no frizz, ends are nourished not greasy at all. My hair is colored and gray underneath. If I do not get a good blow dry, it becomes frizzy. This heat protection is no joke. No silicone or plastics in this high quality product so your hair can still take in nutrients from the air and sun and doesn’t block healthy normal hair. Excellent product!!

Love this spray for my curly hair. Works great. Great curls. No scent. Hold is good. No stickiness or greasy feeling

Maybe because I used this on damp hair after towel drying, it wasn't greasy even though I though I applied a generous amount. In fact, it didn't seem to weigh my hair down at all. My hair was smooth and shiny but especially softer. There is no added fragrance. The scent of the ingredients is rather pleasant, light, and doesn't linger. Yes, this is watery. I wish the spray was wider. It's closer to a stream than a spray, requiring me to work it more through my fragile hair. The bottle arrived unsealed. I don't prefer this product enough to pay $22 for it.

This product has been a game changer for my hair, it's become so soft and shiny.

This serum is good for calming my frizzies. It is easy to use and I only need a little bit for my fine hair. It adds shine and softness. Very happy with this. Oh, and it smells wonderful.

I love using this spray on my freshly showered towel dried hair. It makes it so smooth and soft. I have a lot of very long hair that is also very fine, this serum helps it lay flat and not get tangled. I’ve recently discovered it also works beautifully on my 11 month olds hair. As you can see in pictures his hair is normally out of control but one spritz of this spray and his curls are smooth and no longer sticking straight up. With these ingredients I felt good about using this on his delicate head.

I didn’t notice any difference in my hair with this. It has a strong scent and didn’t help with any frizz like I was hoping it would.

I used this serum in conjunction with another product from this same company. I will say they make a great team. My curls weren’t overly frizzy, and they stayed that way all day. I will def be buying them both again.

This is an interesting product. It claims to do a lot of things, such as ‘nourishing’ your scalp, but I bought it for its defining properties. I have to say I am a little bit disappointed in this aspect, as it doesn’t do anything my £12 product does. Average definition, even if I use a lot of it. It is also quite thick, which I wasn’t expecting. It is easy enough to apply and I find less actually gives better results. There is a neutral scent similar to other Rosebrook products. It’s not bad and also not amazing. Just pleasant. The price of £22 is the real downfall of this. I understand they have to make a profit and they are a small company compared to the big namebrands, but they cannot compete on price, and the quality difference is not noticeable in my experience. Overall I will say if you can get it for about £15 then it’s worth a look if you have a LOT of frizz.

The smell is not bad and has a light herbal mix that is pleasant enough. It does not feel harsh on the scalp and the idea of a weightless serum sounded good. I was hoping it would smooth my waves and control frizz without leaving build up. The issue is the spray itself. It does not mist at all and instead pumps out small streams that feel like thick drops of water hitting the scalp. The product also feels like oil mixed with water and leaves an oily residue on the hair. It does not match the purpose described and ends up weighing down the hair rather than defining it.
