Best heat protection product for hair

Fantastic styling product that protects your hair from heat damage. Leaves your hair really smooth and shiny none greasy. Perfect on my fine hair. I haven’t had any other product as good as this for heat protection. Well worth buying.

My least favourite product from Kerastase

This product had little effect to tame frizz on my hair and would not purchase again. Loved every other product have bought from this brand but this one made no difference to my hair and have had better results with supermarket bought styling creams

Works well

Sometimes I'm left wondering if hair products have done much, but this definitely makes a difference. I have fine wavy hair, but lots of it, that is prone to frizz. Absolutely love the scent.

Not impressed and will return

I’m normally a fan of their products and although I gave my hair a smooth feeling after being blow dried, it made my hair even more vulnerable to frizz so no matter how well it protects, it does not wear well.

Pretty impressive

I have fine and curly hair that I blow dry straight-ish, wavy-ish every time I wash it. Normally, I would have to touch it up every morning - but since discovering this product, the only time I use heat is immediately after the shower. Hair stays as is after that.

10/10

Really adore this blowdry lotion and I have repurchased this multiple times. Product feels like a hybrid between a nourishing gel and a serum. Very lightweight and leaves hair silky and soft. A protein free heat protection suitable for frequent use for low porosity hair. Fascinating technology that prolongs and preserves your blow dry shape - this really does work and I trialled it side by side. I love that this product has excellent heat protection too. I will always select this product when heat styling and it's a great oil free heat protectant for when using a higher heat. Wouldn't be without this. Very luxurious packaging. Simple but elegant and clean fragrance.

Allergy alert all ingredients NOT listed on web

It has Isopropyl Myristate in the ingredients. The ingredient is listed on the bottle, but not on Kerastase website or Sephora's (that is probably not Sephora's fault, they just copied and pasted from official Kerastase). This has to be illegal. Allergies are a thing, to not list an ingredient EVERYWHERE is false advertising. I always check ingredients before ordering. I bought this because all the ingredients were safe for me. If I did not read the bottle I would have a severe reaction. RETURNING THIS ASAP

Honestly cuts down my blow drying time. I have thick frizzy hair. But when I work a few pumps of this product into my blow dry routine dry time goes from 1hr to 40 min. Plus it leaves my hair hydrated!

Worth the price

Works very well, leaves my hair silky and frizz free.

finally! a hair product that made my hair look like I walked out of a salon... after blow drying my hair it was like silk! I'm coming back to buy the large bottle

what a great product

Really great product for hair which are stubborn. I have quite fine hair however with this styling product they doesn't become greasy and heavy, just opposite. So light and volume during blow dry - wow. And smell absolutely divine

A Must Have for Thin Hair

Is there an option for 10 stars? I work two pumps into crown of head then section hair and apply R&Co. Dallas (thickening) spray before drying with an airwrap and - ta-da - perfection! Pros - works great on fine oily hair, still feels fresh on day 2 hair, no strong odor, bottle lasts 4+ months with 3 hair wash days a week. Cons - it is possible to use too much (start with small amount)
