Great for my hair

5 stars out of a maximum of 5

This product is great for my hair, makes it really soft and shiny and easy to manage. Definitely gonna try the shampoo and conditioner too

Disappointed

2 stars out of a maximum of 5

Having bought this many times before from Look Fantastic and other sites this time I found the product much thinner than usual so much so that I would question the authenticity of it, but generally and usually if your hair is a bit frazzled from straightening or suffering from colouring too often this makes it feel lovely and I think the matching shampoo really helps

Okay-ish

I used this product with Redken color extend duo (shampoo and conditioner) and didn't see any difference to my hair. Although the product claims that it can hep to repair and strengthen your dry, damaged hair (which is my hair type), it does nothing to strengthen your hair in long term. Just another expensive protein treatments!

Amazing

5 stars out of a maximum of 5

This is the best conditioning treatment i have ever used. I changed my hair from blonde to brown, back to blonde and now it's brown again! So my hair has been through a lot and this conditioner has definitely helped keep it in lovely conditioner!

Excellent Product

5 stars out of a maximum of 5

I previously purchased the shampoo and conditioner in this range and then this product which really conditions my hair beautifully without weighing it down . I have very fine , wavy , coloured hair prone to Frizz which had become damaged due to use of curling machine and the fact get I live in a hot country . I am delighted with the whole range which had improved the condition of my hair within a relatively short time frame
