I read about this in the Evening Standard magazine last night (a terrible magazine but it is free) and I think we need to try it. It gives your hair volume, makes your blow dry 'stick' and gives your hair texture. It does the opposite of serums, oils and conditioners and roughs your hair up a bit. I am intrigued and think I might have to investigate as summer is coming and beach hair is where it is at, no? You can read more about it here.
