    TLDR The most effective way to diagnose non-scarring hair loss is by transverse sectioning, and some cases, particularly in males with inflammation around hair follicles, might be curable.
    In 2018, a study was conducted on 114 Iranian patients with non-scarring alopecia. The most common type was Androgenetic alopecia (AGA), followed by alopecia areata (AA) and combined AGA/telogen effluvium (TE). Perifollicular inflammation was found in 21% of AGA cases, with a significant difference between males and females (66.7% vs. 33.3%). The study concluded that transverse sectioning was the most effective method for diagnosing non-scarring alopecias, with a diagnostic rate of 88%, compared to 33.6% for vertical sections. The researchers suggested that cases with perifollicular inflammation, especially in males, could potentially be curable.

      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.

      A 29-year-old woman is experiencing gradual hair thinning since age 15, suspects Androgenic Alopecia, and has tried 5% minoxidil with little success. She has purchased various hair loss treatments including minoxidil, dutasteride, finasteride, and spironolactone, but is cautious about starting them due to potential interactions with her ADHD medication.
