Male-Pattern Hair Loss in Norwegian Men: A Community-Based Study

Multiple community-based studies in Norway have found that male-pattern hair loss (MPHL) is prevalent in Norwegian men, with prevalence increasing with age. The studies found that men with hair loss were more bothered, concerned, and dissatisfied with their hair appearance. MPHL was also associated with negative effects on self-esteem and quality of life. The Norwood/Hamilton hair patterns were used to categorize hair loss severity. The studies suggest that a high proportion of Norwegian men experience MPHL, and cultural differences may affect the interpretation of questions and pictures used to assess hair loss.
