No one at any age wants to lose hair. Its natural thing like aging but no one wants it to happen. When your old and have wrinkles I guarantee you 20 bucks you will not want to be older. It happens but its never something you want. Losing hair will hurt no matter the age even though you think it wont matter. I promise it will hurt just as much at 40 as at 20 its just that because your young you think that now.
