Many people in the U.S. are familiar with hair loss. About 30% to 50% of men will experience male-pattern baldness, or androgenetic alopecia, by the age of 50. The condition is characterized by thinning, loosening, and loss of hair, typically on the head. But, as it turns out, men in some states are treating hair loss more than average.

New research from GoodRx, a platform for medication savings, shows that the pursuit of fuller hair varies dramatically by geography and health insurance.

To be sure, the geographic disparity in fill rates isn't due to genetics. Male-pattern baldness is common across the U.S., but the willingness to treat it depends on money, access, and social acceptance of hair loss and baldness.

Hair loss is common — around 30% to 50% of men will experience male-pattern baldness by age 50. Yet treatment isn't universal, and prescriptions to treat it vary widely across the U.S.

Washington D.C., leads the country, filling hair-loss prescriptions at more than five times the national average, followed by Massachusetts, New York, and California.

West Virginia sits at the bottom, with fill rates at just one-quarter of the national average, with Mississippi and North Dakota also among the lowest.

Wyoming has a hair loss prescription fill rate of 0.27% which is lower than the national average of 0.7% and ranks as the #4 lowest among all states.

The nation's capital takes the crown. In the District of Columbia, 3.7% of all prescriptions for men ages 18 to 44 are for hair-loss drugs. That is five times more than the national average (0.7%).

Other standout states where a significant percentage of prescriptions are filled include:

Together, these states and cities highlight a pattern: The states with the highest fill rates for prescription hair-loss medications tend to have a higher average income. They are also home to urban centers where professional polish may be of extra importance.
