Well I live in the UK so I got my nanogen from the manufacturer website.

I have always thought that it's impossible to get in the US which, I assume, is why so many people use toppik instead.

I haven't used it, but it seems to me that Nanogen would be pretty fussy.

Would this stuff just come out if someone played with your hair a little? Sweat? Stuff like that?

that has been my fear. i will say that i came to this forum tonight specifically to sing nanogen's praises though.

previously, i've tried sprinkling nanogen on sparsely and i haven't been sold on nanogen. i think it works best with shorter hair styles rather than longer, at least it seems as it has with me.

i also found that being sparse with it just doesn't work. you have to be pretty liberal with it. i did that tonight and man...i was really amazed. it was by far the best my hair has ever looked with nanogen, and again, it was simply because this time i didn't try to cut corners with the amount i was using.

however, "imissme", that is the problem with nanogen. i simply can't trust it. it comes off VERY easily when you scratch your head. sweat not so much, at least for me, but it comes off very easily even when you are scratching your head really lightly. for that reason, dermmatch might be another option for me. it seems like a pain to put on though, and even with this, i'm assuming, if you scratch your head, it would come off on your fingers?

but, for an interview or in any setting where someone wouldn't be touching your hair, nanogen works really, really well.

I use a dermmatch/toppik mix. Personally, I tried nanogen, but I did not like it and I don't like the fact that you can't open their bottles to find out how much is left.

Also, with toppik, I put down some newspaper on my sink and it catches the left over, which is easily poured (via newspaper crease) back into my toppik canister. This saves me a bunch of toppik during each use and keeps my bathroom very clean.

As for sweating, etc. I do use hairspray to hold it in place, but I still don't let people touch my head. It's instinct now to block someone from touching my hair even if I touch it and nothing comes out.

A lot of people say nanogen is better than toppik.
I really should give nanogen a try then
