It is a good one but not my favourite 

It works well but you have to use a lot of product.

I'm not sure I get the hype for this product, doesn't seem to make much of a difference for me

This is actually terrible. Yeah you feel hydrated when you apply it (although a bit sticky) and it smells nice but the colors develops uneven and as mentiontioned doesnt do any favour for cold toned skin people. 

Philiip Kingsley elastizer is a favourite of mine. I use it every week and hate to run out of it. It treats my dry hair perfectly and nourishes it so its noticeably healtier looking.
