Works great but strange smell
[This review was collected as part of a promotion.] I have used other anti frizz coats by other popular brands and this one seems to work in a much similar way; coat the damp hair and the results are activated by heat. The result was great and it left my hair really shiny, glossy, and easy to handle. I even used it on my hair extensions and they turned out fab too. I would have preferred a spray applicator as you need to coat the hair fully so was a bit of a slight annoyance to keep going back for the pump but that wasn’t a big deal. The only thing I really did not like was the smell. It was slightly chemically smelling when you’re first using it. I would say though that the smell isn’t noticeable at all once you’ve dried your hair but it was a bit off putting and I personally prefer nicer smelling products on my hair that will be fragrant for the day.
I’m not certain I would buy this again as I feel there are other products on the market which do the same thing but have a spray applicator and smell better, but it’s certainly not a bad product at all and I’m glad I was able to try it
