I think Donald Trump owes this guy a ton of money.

United States Patent: 4022227

1. A method for styling hair to cover bald areas using only the individual’s own hair, comprising separating the hair on the head into several substantially equal sections, taking the hair on one section and placing it over the bald area, then taking the hair on another section and placing it over the first section, and finally taking the hair on the remaining sections and placing it over the other sections whereby the bald area will be completely covered.

BACKGROUND OF THIS INVENTION

For those people who are partially bald and wish to cover the bald area hair transplants, hair weaving and hairpieces are the most commonly used solutions. The cost of covering bald areas by one of these methods can range from a few hundred dollars to thousands of dollars depending on a person’s choice and financial means. Some of these commonly used bald area coverings require periodic care, which generally cost money.

Obviously a partially bald person without the financial means can not afford the luxury of such hair coverings. This person, therefore, has few options; he can attempt to use his own hair to cover the bald area, but generally most people do not have the ability to properly plan a hair style that will look good, and most attempts result in brushing the hair in one direction over the bald area, or he can allow his baldness to show.
