TLDR Physical exams are important in hair loss diagnosis, considering cosmetic history, systemic diseases, and classifying alopecia types.
The document from March 19, 2021, discussed the importance of physical examination in trichology, noting that 17.5% of dermatologic consultations were related to alopecia, accounting for 12.1% of total billing. It emphasized the need to consider a patient's cosmetic hair care history, as improper or excessive use of chemical products could lead to acquired hair dystrophies like bubble hair. The document also highlighted the need to look for signs of systemic diseases such as anemia, thyroid diseases, and emotional stress in cases of telogen effluvium. It stated that hair color, determined by the amount of eumelanin or pheomelanin granules, was not a significant factor in alopecia. The document classified alopecia into three categories based on clinical presentation: diffuse, circumscribed, or localized alopecia.
