Brilliant

I have been using this oil for the past 4 or 5 years now and I absolutely love it. It is not greasy, keeps my hair in a great condition and protect it from split end. Very light ,not even feel that I've got it, but if I miss it, my hair knows!

Great for Thick Hair

This is the thickest serum currently available from the Kerastase line that I have tried. One pump can easily be too much for my thick shoulder length hair so I use half a pump. Hair is left feeling healthy and moisturized, it also offers decent shine. I especially like using this for blowouts as it offers some heat protection and gives my hair a bit of weight so it is not nearly as puffy as it can be when I go without. I also use a small drop on my curly hair once it is dried as a sealant. Very similar to the old Loreal Professionals Textures blow dry balm and serum in the gold bottle from the mid 2000's. In fact, Im fairly certain this serum is identical to the serum from that now discontinued and much cheaper priced salon line.
This bottle will last you well beyond the 12 months listed on the bottle. Store it in a cool dry place (ie not the bathroom) and it will be fresh for years.

Expensive but worth it!

This is holy grail for your hair. Kérastase may be expensive compared to other brands but once you start using it, it's impossible to go back. This serum helps tame my baby hair and frizz. During the summer, my hair tends to get oily faster, so I would apply this on damp hair. VS. in the winter, when my hair is drier, I apply this after my blowdry. Not to mention, it smells SO good. A small drop of this goes a long way. Highly recommend!

Best hair oil

I try Karastase for high-quality hair care products and this hair oil definitely doesn't disappoint! The product adds a nice shine with a smooth, silky finish, and never oily-looking like other products. I also love the smell of this hair oil, and it's worth every penny!

Favorite product ever

This oil is fantastic for long unruly hair. I use it after every shower and it makes my hair feel really soft. Its scent is quite strong, but it is one I enjoy.

Pricy, but definitely worthy

I bleached my hair, dyed it pink and bleached it again. It looked awful, breaking all the time, extremely dry. I purchased this oil and it helped me so get much! My hair is slowly starting to look normal and healthy again!

Soft hair

I have been using the Kérastase serum and it has changed my hair. My hair is looking so much healthier. I use it weekly and just love it! Highly recommend!

Makes hair smooth

This is one of my go-to products. I use it after washing my hair cause it makes brushing easier. I also use it once the hair is dry to control frizz and make it look silky. Just 1 or 2 drops is enough.

Good

Pricey but you can see the result instantly, makes your hair soft and glowing. The amount you get for the price also reasonable. I am not sure if i would buy it once again due to price.

Beautifying oil

This versatile beautifying oil is perfect for fine hair. You can use it as a mask or leave in treatment on wet or dry hair. It’s so weightless, make hair look shiny, smooth and defrizzes. I use it on wet hair and on dry hair as it beautifully defines my wavy hair, making it look very glossy and renewed.
