Hi there!
I have two answers for you, depending on your lifestyle, likes and dislikes and the amount of money you want to spend.
1. As BB said you can use some natural remedies, i.e. rose-water. Another lady of the board and myself, use that. The scent of rose is quite "freshening" and most people tend to love it. I don't know if it can mask entirely very heavy smoke odour though. So far it works for me, but for light smoking environments.

2. Do you have the Shiseido line of cosmetics where you live? They carry a "Hair and Body Freshener" spray which does exactly that, both to hair and to body, i.e. after frying french fries and people come over for dinner before you have time to shower. I have used it in the past for my hair, especially in winter because here smoking is still allowed almost everywhere and I hate the smell. It is extremely good in absorbing the smoke odour although it does have a light perfume of its' own but not an unpleasant one. I haven't used it for ages and had to go dig it out of obscurity to remind myself of its' name. It is really good, but it's a commercial cosmetic.

Hope these help
