Frizz free
[This review was collected as part of a promotion.] The scent of this product alone would make me repurchase. Its a gorgeous perfumed slightly floral slight heavy smell that lasts all day. I do find my hair feels nourished after using but i do wish i didnt have to blowdry to “activate” it. I have tried both blowdrying and not and i do feel you have to apply some sort of heat to ensure the product is able to lock your frizz down.

Great but smells
[This review was collected as part of a promotion.] I really do like this oil, it helps my frizz and doesn’t seem to burn if i’m straightening my hair like other oils do but it has a really weird scent. I do have to layer a different hair product over it to get rid of the smell since i don’t want it to linger but otherwise my hair feels smooth and soft.

Great product
[This review was collected as part of a promotion.] I have very coarse, frizzy and thick hair so struggling in this heat trying to style my hair and keeping the style throughout the day! This product has made a considerable difference, my hair feels sleeker and actually keeps the frizz at bay - added bonus that it is also a heat protectant which is key as my hair is quite damaged.

Genuinely works (better than anything else I’ve tried on my hair)
[This review was collected as part of a promotion.] This product genuinely works. I’ve tried high end oils for my hair as my hair is quite damaged and frizzy, usually stands up straight. However. I’ve used this a few times after washing my hair and my hair looks like I’ve straightened it. It also smells delicious which is a big bonus. I really would repurchase again. 10/10

Holy grail serum with one tiny warning!
[This review was collected as part of a promotion.] Okay, this new hair serum is officially a must-have. It smells so good and makes my hair incredibly soft. If you have frizzy or curly hair, it’s amazing for detangling and smoothing everything out without leaving that heavy, oily feeling. My only warning is the packaging, the pump squirts the product out fast. Just be gentle when you press it so you don't get it on your clothes. Def worth a try!

Amazing
[This review was collected as part of a promotion.] I have wavy/curly hair, which means in the summer it gets really frizzy even if I heat style it, when I used this product I had no frizz and my hair didn’t ‘puff up’ from humidity, it’s great and I’d definitely recommend it!
