After writing the book and creating the term, Generation X, Douglas Coupland tried his hand at identifying the post-post-babyboomers (sometimes called generation Y) One major difference was that they were very concerned with appearances and took beauty supplies seriously (Thus the title "Shampoo Planet")

I think you are in that generation, or close. I'm near the end of his GenX definition. This way, you can fully blame your addiction on your generation. Glad to provide the goat for scaping!
