Hair & Scalp Reference
Hair Loss & Scalp Health Statistics
A carefully sourced reference for writers, researchers and anyone looking for context on hair loss. Last updated September 28, 2026.
Hair loss has many causes, and the numbers below describe specific populations, conditions and study periods. They are here to make responsible reporting easier, not to diagnose a scalp concern or promise a product result.
80 million
Americans are estimated to have hereditary pattern hair loss.
The American Academy of Dermatology breaks that estimate into 50 million men and 30 million women. Pattern hair loss, also called androgenetic alopecia, is the most common cause of hair loss.

Was the annual prevalence of alopecia areata in a large insured U.S. population in 2019.
The study estimated an annual prevalence of 0.199% in 2016, rising to 0.222% in 2019. Alopecia areata is an autoimmune form of hair loss and is distinct from pattern hair loss.

Are the published study estimates cited for CCCA among women of African descent.
Central centrifugal cicatricial alopecia, or CCCA, is a scarring form of hair loss that has been reported predominantly in women of African descent. These figures come from separate studies, not a single national prevalence survey.

Cases of alopecia or hair loss per 100,000 person-years were recorded among U.S. active-component service women.
This rate covers 2010–2022 and describes one specific service population. It should not be read as a rate for all women or as a diagnosis estimate for any individual.

Hair loss is not one condition. Pattern hair loss, alopecia areata and CCCA have different causes, patterns and research bases. A figure from a study of insured adults, service members or a specific community should stay in that context when it is quoted.
For a new bald patch, sudden shedding, scalp pain, itching or persistent irritation, the American Academy of Dermatology recommends seeing a board-certified dermatologist. Everyday hair care can support a comfortable routine, but it does not diagnose or treat a medical condition.
