Genesis, Nourishing and Fortifying Blow-dry Spray Cream, For Weakened Hair, With Ginger Root and Edelweiss Flower, Defence Thermique, 150 ml

I’ve been using Kérastase Genesis Leave-In for years, and it has become an essential part of my haircare routine. I have wavy hair that tends to get frizzy very easily, especially with humidity or after blow-drying. I apply it to damp hair about 3 times a week after washing, using 3 pumps distributed through the lengths and ends. From the very first application, I noticed my hair felt much more manageable, lightweight, and shiny without feeling heavy or greasy. What I love the most is how well it controls frizz—my hair stays soft, smooth, and healthy-looking. Another huge plus is the scent: fresh, elegant, and with an incredible lime note that makes the whole experience even more enjoyable. The price is definitely on the higher side, but in my opinion it’s worth every penny because the quality is noticeable and a little product goes a long way. I’ve repurchased it for years, and it’s still one of the best haircare products I’ve ever tried.

Fantastic product saw a difference from first use on my very fine bleached hair. not heavy at all doesn't make it feel greasy just very soft and shiny .it's expensive but worth every penny .also smells lovely

Okay, so let’s be real — this kind of product is impossible to review right away. You can’t just spray it once and declare, “Wow, my hair is saved forever!” You only truly know if it works after weeks (or months) of heat styling, when you start noticing whether your hair still breaks or not. I’ve only been using this heat protectant for about a month, so I can’t yet say if it’s a total miracle. But here’s what I can tell you so far. My hair is bleached blonde, which means it needs constant attention, moisture, and protection to avoid dryness and breakage. I’m very picky with anything that touches my hair. And this spray? Honestly, it surprised me in the best way. First, the texture — it’s not your usual liquid spray. It’s got this creamy consistency, almost like a lightweight lotion, but somehow it still sprays evenly! I find that absolutely genius. It feels richer and more nourishing, which gives me extra peace of mind knowing my hair is actually being coated with something protective, not just misted with water. The scent is pleasant — soft, fresh, and clean. If I’m being totally honest, I could imagine it being a bit more “girly,” maybe something floral or sweet, but I get why they went for a more neutral fragrance. It makes sense — guys use heat protectants too. Overall, I’m really enjoying this product so far. It’s a must-have in any hair care routine if you don’t want your strands to snap off every time you blow dry or straighten. That was my problem for years — my hair just wouldn’t grow past a certain length because it kept breaking. So while I can’t say yet if this will be a total game-changer in the long run, I can already tell it’s different. Creamy, protective, pleasant — and honestly, kind of revolutionary for a heat protectant.

This is an excellent product and one of the best heat protectants we have used. It leaves the hair incredibly soft, silky, and smooth without making it feel heavy or greasy. The hair is easier to brush and looks healthier and shinier after styling

I love this product. It smells nice and leaves my hair smooth and manageable.

It smells like a luxury salon perfume and actually lasts in the hair all day. I’ve had people ask what perfume I’m wearing and it’s literally just this.l! Performance wise, it makes my hair feel softer straight away, helps a lot with detangling and gives a nice natural shine without weighing it down. My hair is fine and usually gets flat with creamy products, but this one didn’t make it greasy or heavy at all. I’ve also noticed less breakage on the ends when I use it consistently. How to use it properly: – Use a small amount. A coin size is more than enough or it can start to feel heavy – Apply only through mid lengths and ends, not the roots – Use on damp hair before blow drying and comb through to distribute evenly – For that extra smooth “salon finish” look, finish with a cool shot One honest note: if you’re expecting it to stop hair fall completely, it won’t. It helps with breakage because of heat protection, but it’s not a miracle anti hair loss treatment. Real verdict: not a must have… but once you try it, it’s hard to go back. Addictive scent plus smooth, polished hair is a dangerous combo for your wallet

Gorgeous smell especially when dried, actually makes my thin hair feel a little bit thicker when it’s blowdried! Expensive but worth it.

All the products from Kerastase normally are great so nothing to claim

It has a good fragrance but doesn’t help with frizzy hair until used in large quantities.

Great hair product, however it arrived with a small cut in the base of the bottle which resulted in it leaking.
