KERASTASE Nutritive Heat Protecting Spray | Nourishing Heat Protectant for Dry Hair | Detangle, Reduce Frizz & Fly-aways | For Fine to Medium Dry Hair | Lotion Thermique Sublimatrice | 5.1 Fl Oz

The holy grail of hair care products! I have fine hair and this product is lightweight yet effective. It doesn't weigh my hair down or make it greasy and it hydrates my thirsty hair making it soft and shiny. It smells and feels amazing, I just wish it weren't so expensive

Really helps my brushing my fine hair after the shower. I use it every single time I get out of the shower and have really noticed a difference in my hair. It is a little pricey but definitely worth it!

Has a great scent, wonderful quality, leaves hair super soft. I use this after my wash on wet hair, and then add a lightweight gel for a quick wash and go. Since it’s so lightweight, it dries quickly. Works great as a light leave in with NO stickiness.

Does a good job overall in protecting the ends of my hair when I heat process via a warm-to-hot blow dryer and flattening iron 2 to 3 times per week. A bit pricey, but I have found the less expensive brands don’t work for me as well.

Very nice on my hair

This isn’t my first time buying it — it’s become indispensable for me. I use it before going to the beach, straightening my hair, using a hairdryer, or simply after washing my hair without heat tools. The price is fair for its size. The scent is okay — it would be nice if it lasted longer, but it fades after a while. Still, it really protects and nourishes your hair from heat and sun damage, preventing dryness. The only downside was that it arrived later than expected.

My hair was severely damaged from the heat, and this product was the best thing that ever happened to it. Now it's super hydrated and shiny.

I saw a real difference in my hair density! I have very fine hair and after using this leave in conditioner my hair was visibly thicker, with stronger curl pattern and healthier looking.
