I originally bought this product when i was on holiday in America because i fell in love with the other Burt's Bees products which i had bought there too.
Its safe to say this product did not disappoint either. You do not need a lot of shampoo as it is quite soapy so builds up a lather that covers your hair (i also have thin hair).
It is strange because once you have rinsed your hair it doesn't feel that great, but once you have brushed and dryed it it feels really soft and silky! The main difference to this shampoo compared to others is that your hair looks really shiny after! I'd also recommend using the conditioner after the shampoo.
The only dowsides to this product are that it is quite expensive. I'm not entirely sure how much it is here but i think it is between £8 and £9. Another downside is that i think it has a high soap content which strips coloured hair if used regularly. I like to use this product periodically to prevent this. It also means it lasts for a while too!
