This makes my hair soft and I also use it on my frizzy hair during the day as it absorbs quicly and is not greasy. Very expensive though

Great serum especially for frizzy hair Leaves the hair soft and not frizzy 

Really good serum. Leaves my hair feeling much softer and less brittle. Highly recommended 

I normally love Kérastase products so I was looking forward to trying this hair serum on my bleached hair, as I liked that unlike overnight hair oils, I wouldn't have to wash this product out in the morning. However, I honestly feel like this serum made no different to the dryness of my bleached hair at all. So I won't be repurchasing this product. Maybe it just wasn't suited to my hair type, as I find overnight hair oils much more effective.

A friend recommended this product to me as we have both experienced dry hair snapping off at the back… this is the first time in my life where hair care has become a priority as well as skin care. This product has made my hair feel soft, nourished and hydrated.  A little goes a long way, I am expecting this product to last for a long time.
