    TLDR Trichoscopy is a useful method for identifying primary cicatricial alopecias and their specific types.
    The 2016 study evaluated the effectiveness of trichoscopy in diagnosing primary cicatricial alopecias (PCAs) and their subtypes. It involved 100 patients with PCA, 100 with non-cicatricial alopecia, and 100 normal individuals. The study found that certain trichoscopic features, such as the absence of follicular opening, perifollicular scale, and specific vascular patterns, were highly sensitive and specific for PCA and its subtypes, particularly discoid lupus erythematosus (DLE). The absence of follicular opening showed 100% sensitivity and 99.5% specificity for PCA, while tortuous branching vessels and follicular keratotic plugging were 100% specific for DLE. The study concluded that trichoscopy is a valuable non-invasive tool for distinguishing between cicatricial and non-cicatricial alopecias and for aiding in the diagnosis of PCA subtypes, although it acknowledged limitations due to the small sample size for certain conditions and recommended further research with larger sample sizes.

      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.

      community Testosterone and hair loss seeming irrelevance

      in Research/Science  81 upvotes 2 years 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.

      A user visited a dermatologist for hair loss concerns and was prescribed a hair lotion called "Lotion revolotion evdermia," which is meant for hair toning, hydration, and anti-aging, not regrowth. The user found the dermatologist's behavior and the prescription to be questionable.
