KERASTASE L'incroyable Heat Protecting Strong Hold Styling Hair Serum

The best hair product I have ever bought. Makes my hair tangle-free and shiny. I can’t go without it now. My hair is stronger, soft and more manageable than it has ever been.

I tried this on a bit of a whim, but I am so glad I did! This has been a great product for me, and I just bought my second bottle. I have fine hair that needs all the help it can get in styling and holding that curl. This product has been a wonderful discovery and beautifully holds my hair without feeling stiff.

My hairdresser recommended this to me to try - but I'm a drugstore & thrift store girlie, I save where & when I can bc most times, paying for name brand or new means spending more for no reason. This stuff is where I bend my rules - yes it's still what I would call expensive at $48 for 15mL BUT I have had the same bottle for over a year now. You only use about the size of a quarter at most (I have midback length hair). I absolutely love that I live in hot humid Florida & can finally have a decent 'do!! I use it at least once-twice week when I wash & blow out hair. It's made a huge difference in the condition of my hair & as stated, I only have to really do a full blow out a fraction of the time bc this makes it so easy to rewear & restyle. Highly recommend!

I didn’t like this at first and I had to give it a couple more chances and now I love it. At first, I didn’t think it worked well and I thought it smelled like granny. I wasn’t using it properly and when you style your hair with the serum, it actually smells really good after. It is a strong smell though, just as a warning for people with sensitivities. I have 2b hair for reference so it’s a little thin but it has curls/waves and my hair will still try to curl on its own after I blow dry with this. My hair is a little past my shoulder and I use two pumps of this serum and then I continue to blow dry my hair as usual and my hair turns out shiny and soft and it will stay as I styled it for a few days until I wash again. Thumbs up from me!

This is the best blow dry serum for my fine, straight hair. It’s pricey but worth the price. I originally purchased this online from another source because they had it for a few dollars cheaper with free shipping. It was mailed unprotected in one of those bubble wrap mailers, across country through the USPS, and the tip got broken (there is no protective cap on this item…something that Kerastase should reform), the top was not in the locked position and there was product all inside the bag. Fortunately we had a physical store in town, I put in for a refund and was able to return it to the store and get my refund. Since no physical beauty store in my small town had the product, I turned to Amazon to order it this time. It arrived safely, but was in a plain brown envelope with no padding. I think that it arrived safely because it was packaged and picked up at the nearest large town 50 miles away and delivered by one of Amazon’s drivers so it didn’t get banged around in the mail. However, I would hope that for deliveries that do go through the mail, that they are protected (shrink wrap would be nice) and put in a box for those shipments. Maybe they are. Most of the beauty products that I buy through Amazon, are. But as for the product, it works very well, andds volume and doesn’t weigh down my hair. I’m not any good with the round brush and a blow dryer though so I just put a small amount of the serum in my hand, rub my hands together and blow dry my hair. I wash my hair at night. In the morning, I use a little mousse and a curling iron to style it. Heat reactivates the serum. I have a modern cut and it’s a great cut, but I’m able to get the same result using a curling iron and combing into place as my stylist and I’m sure many other more dexterous people are able to do with a round brush and hair dryer. Heck, I’m in my 70s, it’s enough just to have a modern cut that works with my hair. I hope that my stylist who is in my age bracket, never retires.

Love this product to help take blowouts to the next level! I recently got a Dyson and was trying to find the best heat protectant and blowout cream. I was nervous about trying this one because it was more expensive upfront, but I’ve been so happy with the results. Creates a quick dry, heat protecting and nourishing blowout, and the product smells great to top it all off.

I got this as a sample when I went to the salon, and I really loved it. I purchased the full size and tried and it out and it seemed to be the same result, which was smooth, volumized hair. My only recommendation is to AVOID putting this product anywhere on the hair above your forehead, as it will create too much of a shine and get a bit greasy throughout the day. But for a blowout, it’s a great product.

My favorite go to blow dry serum. It keeps my hair shiny and smooth. Eliminates my fly always. I have since grown my hair out and I use it every time after I wash my hair. I highly recommend it It is very expensive but you get great quality. You don’t have to use much for your hair just one squirt. I love this product! I have been using it for years. At least 10!

Uso Kérastase L’Incroyable Blowdry su capelli sottili e ondulati e nel mio caso è uno dei prodotti styling più equilibrati che abbia provato. La texture è leggera e facile da distribuire: ne basta davvero una piccola quantità per lavorare bene su tutte le lunghezze. Non appesantisce e non lascia sensazione appiccicosa, aspetto fondamentale per chi ha capelli fini che tendono a perdere volume. Mi piace perché aiuta a rendere lo styling più ordinato e controllato, mantenendo comunque movimento naturale. Inoltre svolge anche una funzione di protezione dal calore, cosa che trovo molto utile quando utilizzo phon o diffusore: permette di semplificare la routine senza sovraccaricare i capelli con troppi prodotti. Dopo l’asciugatura i capelli risultano morbidi, gestibili e con una buona definizione, senza effetto rigido. Lo consiglio a: ✔ capelli sottili o delicati ✔ capelli ondulati che necessitano controllo leggero ✔ chi cerca uno styling versatile e non pesante Potrebbe non essere ideale per: ✖ capelli molto spessi o molto ricci ✖ chi preferisce prodotti molto strutturanti Per me è uno di quei prodotti che funzionano bene nella routine quotidiana: leggero, efficace e facile da dosare.
