    TLDR Trichoscopy is effective for diagnosing hair and scalp disorders without invasive biopsies.
    The study involving 345 patients at a Tertiary Health Care Centre in Southern Rajasthan demonstrates the effectiveness of trichoscopy, a noninvasive diagnostic tool, in identifying specific dermatoscopic patterns associated with various hair and scalp disorders. Key findings include the prevalence of short vellus hair, empty follicles, and hair diameter diversity, with specific patterns like yellow dots in androgenetic alopecia and black dots in alopecia areata. Trichoscopy is highlighted as a valuable tool in diagnosing conditions such as androgenetic alopecia, telogen effluvium, alopecia areata, tinea capitis, trichotillomania, and cicatricial alopecia, potentially reducing the need for invasive biopsies. The study suggests that trichoscopy enhances patient care and calls for further research to understand trichoscopic features across diverse populations.

      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.

      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.
