    TLDR The most common hair loss type at specialist clinics is androgenetic alopecia, especially in younger men, followed by alopecia areata and telogen effluvium, with differences seen across regions.
    In a retrospective study involving 2,835 patients across various continents, the most common type of non-cicatricial alopecia diagnosed at specialist hair clinics was androgenetic alopecia (AGA), accounting for 37.7% of cases, with a higher frequency in males who presented at a younger age (33 years) compared to females (45 years). Alopecia areata (AA) was the second most common, with a median age of 32 years and a higher occurrence in females. Telogen effluvium (TE) was third, with a clear female predominance. Frontal fibrosing alopecia (FFA) was the most frequent cicatricial alopecia. The study also noted significant geographical differences in the frequency of certain alopecias, such as more AA in Europe and more traction alopecia in Africa. The findings, while not reflective of the general population, provide insight into the frequency of hair disorders among patients seeking specialist care.

      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.

      In this conversation, 4990 discussed various treatments for hair loss, including oral minoxidil, PRP, transplan, Jak inhibitors, Dutasteride, Finasteride, Olumiant, Ketoconazole, RU58841, microneedling, baricitinib, and CCCA. They recommended scalp biopsies in unclear cases of DUPA, twice weekly to twice daily shampooing for topical minoxidil users, and two sessions spaced one month apart with follow up at month three to determine the effectiveness of PRP treatment.
