A word that annoys me 'Vanity'

[gmonasco]

What really annoys me is when people write comments saying people should not be so vain when it comes to hairloss. Its obviously not just people commenting on this subject on certain websites, obviously a lot of people feel its vain to worry about hairloss and get hair transplants, take medications to try to cure it.

Really. Plenty of people (both male and female) spend thousands of dollars on cosmetic dentistry, yet I never hear such people described as "vain." Why should hair be considered differently?
