Works great but…

Product works very well and my hair is definitely smoother and shinier post blow dry. I am new to using the Kerastase line so I wasn’t aware of how scented the product was. I am very sensitive to strong scents/odours and would have gone a different direction had I known. No fault to the product line whatsoever but unlikely I will purchase again based solely on scent. Unfortunate as it does work well for my hair type.

It's a great addition to my hair care routine, especially if you use heat styling regularly.

A Must-Have for Heat Styling

I really like the Genesis Defense Thermique Heat Protecting Spray. It is a must-have product for anyone who uses heat on their hair, even just a hairdryer. It feels lightweight, does not make my hair heavy, and gives my hair a smoother, healthier-looking finish after styling. I especially like that it helps me feel more protected when I use heat tools. For me, heat protection is an important step, not something optional. Overall, this is a great product to add to a haircare routine, especially if you blow-dry or style your hair regularly.

[This review was collected as part of a promotion.] Kérastase Genesis Défense Thermique is a lightweight heat-protecting spray that makes my hair easier to style without leaving it sticky, heavy, or greasy. It helps smooth frizz, improves softness, and makes my hair look shinier and healthier after blow-drying. I also like that it helps with detangling and gives my hair a more polished finish. The scent is pleasant and lasts for a while without being too strong. A little goes a long way, so the bottle lasts a long time.
