Love it

My hairdresser used this on me after washing my hair and I instantly ordered one for myself. Only a few squirts and all the tangles are out of my hair and a brush goes through it right away. It smells gorgeous too  and protects my hair from heat. My saviour.

Nice lightweight spray cream

4 stars out of a maximum of 5

It is lovely on the hair, I use just out of the shower on damp hair before blow drying along with a leave in conditioner. I am a bit tired of the scent but it's not too bothersome

This really takes of your hair. No flyaway and the condition has improved massively when using heat on my hair. A must buy!

Nice spray

4 stars out of a maximum of 5

Smells lovely and seems to keep hair smooth when styling but not sure how much it really protects the hair. The spray on the bottle means you need to use quite a lot to cover the head.

Perfect product

5 stars out of a maximum of 5

Bought this when undergoing cancer treatment as it’s so kind to hair and really does help with any breakage, plus it smells divine. Have continued to use this range because it’s so soft and I just love the smell. Worth every penny.

Love this spray whenever I am styling or drying with heat. Smells incredible, makes my hair feel nourished and strong and doesn’t dry it out. Helps with fine hair tangles too
