    TLDR Some hair products can create false signs on scalp examinations, leading to wrong diagnoses.
    In 2019, a study highlighted the importance of recognizing artifacts in trichoscopy, a method used for evaluating scalp and hair disorders. The study emphasized that certain chemicals and substances, such as hair dyes, henna, and vermillion powder, can create misleading signs that mimic specific disorders like early androgenetic alopecia. For instance, hair dyes and henna can penetrate hair follicles, creating a pseudoperipilar sign that may be mistaken for early androgenetic alopecia. Similarly, vermillion powder and powdered colors used during cultural events can create colored dots that may be confused with other symptoms. The study stressed the need for clinicians to consider these potential artifacts to avoid misdiagnosis.

      community Testosterone and hair loss seeming irrelevance

      in Research/Science  81 upvotes 1 year ago
      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.
