TLDR Trichoscopy helps diagnose different hair diseases effectively.

Trichoscopy was a valuable diagnostic tool for differentiating common hair diseases by examining follicular openings, hair shafts, and perifollicular epidermis using a dermascope. It was particularly useful for diagnosing early androgenetic alopecia, distinguishing it from telogen effluvium, and differentiating between scarring and nonscarring alopecias. The article summarized the knowledge of abnormal appearances in trichoscopy and the characteristic features of prevalent hair conditions.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 1 year ago

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.
