Sometimes we complain about things when we have them and then when we lose them we realize that we shouldn't have been complaining. I think having a bad hair day is one of those things.
It might take a little time to fix your hair if it falls out of place because it is, for instance, very windy outside but that is better than having to think about a hair procedure to restore the hair that you have lost. Luckily, however, these days there are some great procedures out there.
