[This review was collected as part of a promotion.] I’m seriously impressed. It feels super lightweight on the hair but still gives that smooth, salon-like finish. I love that it conditions while protecting, especially since I style my hair often. It claims to protect up to 450°F, and my strands didn’t feel dry or fried at all after blow drying and flat ironing. My hair stayed soft and shiny, and it didn’t weigh it down or make it greasy. It’s great knowing that I’m not just styling but also treating my hair at the same time. This might be one of the best heat protectants I’ve used in a long time. Highly recommend if you’re looking for something that works and feels good on the hair. This product was Gifted by k18biomimetichairscience for my honest review.

[This review was collected as part of a promotion.] Love this heat protectant spray! It leaves my hair feels hydrated and protected from any hot tools, it also doesn’t leave my hair feeling super heavy. It leaves my hair feeling soft and healthy without as much damage as I tend to curl my hair a lot! Complimentary from k18biomimetichairscience
