That cornish seaweed shampoo?

Has anyone used this? Is it really that amazing? Tempted by their sale. But it's still stupidly expensive.

Anyone know, If you have coloured hair (Im naturally grey) will it strip the colour?

I have coloured hair and I have been using it for about 10 washes (10 days). It hasn’t affected the colour yet but every day is a bad hair day. I feel like I have a load of product in my hair. My fine hair looks even more lank. I would not recommend this. I’m certainly not persevering for 6 weeks! I might pretend to if that is what it takes to get my money back but I’m not having horrid hair for all that time.
