TOD:
Shampoo: I generally buy the cheap Suave stuff, mostly because I like the variety of scents they use--Citrus, Peach, Mango, Waterfalls (I don't know if that's what a waterfall is supposed to smell like, I do like it.)
Soap: DR MBarnum's favorite--Irish Spring. Also use glycerin soap bought from The Body Shop for my face
Toothpaste: I've never used anything else in my life but Crest.
Deodorant: Pretty much stick to Degree. Again, I like their scents.
Cologne: For the most part, colognes don't last on me at all. I'll put some on and an hour or so later the scent is gone. One exception is Grey Flannel, which does manage to linger on me for hours on end (and I get complimented on it a lot, too!)
At a yard sale years ago, I bought a sealed bottle of Hai-Karate, which I've been keeping on my dresser just for display. Late last year, a friend crack it open and splashed some on. We both discovered that there is validity to the suggestion that you store colognes out of direct light. Phew!
All in all, though, I'm not what you could call a metrosexual. Not that there's anything wrong with that.
