I won a set of these, and as I had recently coloured my hair for the first time, decided to give them a try. Firstly, they are (as they claim) excellent at maintaining hair colour.
However for my fine, long hair, they simply have too much silicone. If I use silicon shampoos, my hair is always lank by the end of the day. It doesn't even need to build up, one use and that's enough.
I ended up giving it to a friend to use, and her hair looks fabulous, but it's thick, wavy and coloured, so much better suited.
I purchased this as a duo pack (larger than the review size, mine was 750ml I think), and got 2 packs for around $70. It's definitely money well spent. The packaging doesn't really jump out at you, I think they were going for something understated so the product could speak for itself but if you are a potential new customer this is probably not going to catch your eye on the shelf next to some of the other brands out there. The consistency is creamy and the scent is pleasant and not overpowering. The shampoo doesn't lather as much as some of the cheaper brands, but I've tried enough shampoos over the years to know that foam does not always equal performance. The conditioner is thick and creamy and you don't need to use much at all - this is probably the first time I've had a shampoo and conditioner last the same amount of time. Usually the conditioner goes first and I'm left with a heap of shampoo at the end :) I definitely noticed the difference in the longevity of my colour with this product. I colour my hair quite a rich red and this product helped it to last a lot longer without fading. Yes it is more expensive than the supermarket brands, but you get what you pay for in this case and because you don't have to use as much, in my opinion it works out more economical in the long run. Just don't let the kids get their hands on it! My first choice for colour protect shampoo and conditioner.
