Light Leave in conditioner spray w/heat protection

5 stars out of a maximum of 5

This is a lovely light leave in conditioner spray with heat protection. Sprays evenly over hair and doesn’t weight hair down. Plus it has a lovely scent. Would recommend

Smells beautiful and protects hair.

5 stars out of a maximum of 5

I love this product. It protects my hair and makes my hair easier to comb through when wet. The whole range has really helped the condition of my hair and with hair loss/breakage. Will definitely continue to purchase.

Good

4 stars out of a maximum of 5

This does leave my hair soft and I often use it even when not heat styling as a leave in conditioner.  It’s very lightweight which is good for my fine hair but if you use too much it can make your hair greasy.  Smell is pleasant and not overpowering.  I’m not sure it’s made any difference to my breakage though.

Hair protection must have

5 stars out of a maximum of 5

This product was prescribed by my hairdresser. Obviously their prices are expensive in the salon so I purchase from Lookfantastic. I use the whole range as I have fine hair with a tendency to break off at the ends. My hairdresser prescribed this product as being the best for my hair type, I’ve used it ever since I have to say I have never looked back, my hair feels amazing afterwards and smells amazing too. Kerastace products are second to none. I would highly recommend this for anyone with fine hair that has a tendency to breakage

Not sure if it is worth it

4 stars out of a maximum of 5

I had so much hope and trust, but had some hard times when using it. It is a good product, but easy to overuse and then my freshly washed hair becomes too "oily" and shiney in an instant. Not sure if the product is not for my hair or I dis aomeging wrong. I plan to delute it and try that way later on

Soft Shiny Hair

5 stars out of a maximum of 5

Im back on Kerastase after stupidly ditching it for the Olaplex range. My hair hasn’t felt better - soft, sleek and manageable. Will definitely repurchase!
