Great heat protectant spray

[This review was collected as part of a promotion.] [I received this product in exchange for my honest review] The formula is lightweight and non-greasy, so it doesn’t weigh my hair down or leave any residue. It noticeably helps protect against heat damage while reducing frizz and breakage, especially when blow-drying. My hair feels softer, smoother, and looks healthier after styling, with added shine. I also love the luxurious yet subtle scent, and a small amount goes a long way, making it perfect for everyday use.

Better hair in a bottle!

[This review was collected as part of a promotion.] [I received this product in exchange for my honest review] I absolutely love the Genesis Defense Thermique Heat Protecting Spray. The packaging feels sleek and luxurious, and the spray bottle releases a perfectly even mist without feeling heavy or wasteful. Application is effortless. It is lightweight, never greasy, and does not weigh my hair down or leave any residue. The instructions are clear and easy to follow, making it simple to use whether I am blow drying or heat styling. The scent is beautiful. It is clean, soft, and refined without being overpowering, and it lingers just enough to leave hair smelling fresh. What truly stands out is how gentle it feels on the scalp. I have a sensitive scalp and experienced no irritation at all. My hair feels smoother, healthier, and more protected every time I style it. This has become a staple in my routine and is absolutely worth it.
