    TLDR Contact allergies might contribute to frontal fibrosing alopecia.
    The study investigated the role of contact allergens in frontal fibrosing alopecia (FFA) by conducting photopatch and patch testing on 63 patients. The results indicated that a significant number of patients showed positive reactions to allergens, suggesting that contact allergy might play a role in the pathogenesis of FFA. The findings highlighted the importance of considering contact allergens in the management of FFA, although further research was needed to establish a definitive link. This study contributed to a better understanding of potential environmental factors involved in FFA.

      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.

      The conversation is about the role of testosterone in hair loss and the effectiveness of different treatments. The conclusion is that DHT is the main culprit for hair loss, and finasteride has been proven to work long-term in maintaining and regrowing hair. Testosterone may have a minor effect, but it is not the primary cause of hair loss.

      A 25-year-old with AGA experienced hair thinning and dandruff, stabilized with topical finasteride and minoxidil but saw minimal regrowth. They seek advice on styling and consider oral minoxidil and microneedling for denser hair.
