Can someone suggest a good volumizing shampoo?

I’ve always used “Samy’s Volumizing Shampoo”, but it isn’t available in the UK. I bought a cache of it home with me on my last trip and it is about to run out. I tried to order some on Amazon.co.uk and the shipping for two bottles was £40! I cancelled my order.

I know that to get volume you should use a volumizing mousse, etc. but I have something I like already. I need a shampoo. I liked this shampoo because it did really work——you got volume and it did not leave your hair weighted or waxy. Most major brands are available here (if you are in the US and reading this.) I have dry ends, if that helps….so I cannot use a moisturizing shampoo.

I’d like a suggestion for a new shampoo…anyone?

Thank you!
