Deodorant UK Style

A little-known and fascinating thing that I learned in the UK is that almost all of their deodorant is spray or roll-on. I'm not sure why - I may have to look into this more. But it was very noticeable when we were at the grocery store. I just looked at the US Dove site - we get two sprays and one roll-on, and then we have the clinical strength option. Do we just sweat more?
