You're going to have to be a bit more specific if you want to know, there are shops etc in many countries, especially in the US, is that where you are?
You can ring Toppik, they might have a store locator, I'm in the UK and using Nanogen, I know they have this system so I'd hope Toppik do to, although I would reccomend Nanogen having a slight edge over Toppik, particularly if you're in the UK as getting Toppik can be a pain!
Hope that helps!
