    TLDR Male pattern hair loss affects about one-third of men aged 18-49 years in the United States.
    Male pattern hair loss, also known as androgenetic alopecia, is a common condition affecting about one-third of men aged 18-49 years. However, previous studies on the prevalence of this condition have mainly focused on clinical populations, which may limit the generalizability of the findings. To address this, a community-based study was conducted in Dayton, Ohio, involving 267 men aged 18-49 years. The participants were selected regardless of their hair pattern, except for those who reported complete baldness. The study aimed to gain a better understanding of the distribution of different patterns of male pattern hair loss and its impact on men's quality of life.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
