    TLDR More people are seeing dermatologists for hair and scalp problems now than in the past.
    The document discusses the increasing trend in hair and scalp-related disorders (HSRDs) consultations in dermatology, particularly during and after the COVID-19 pandemic. The number of scientific publications related to trichology nearly doubled from 1456 in 2011 to 2780 in 2021. New therapies for different types of alopecia have emerged, including low-dose oral minoxidil, platelet-rich plasma, oral dutasteride, and others. A study in Israel showed that the annual number of HSRDs and their proportion with all dermatological outpatient visits significantly increased from 1.24% in 2010 to 9.44% in 2020, with a female-to-male ratio of 2:1. The most prevalent HSRDs included androgenetic alopecia (30.6%), alopecia areata (19.3%), and others. The frequency of androgenetic alopecia and frontal fibrosing alopecia significantly increased over time. The document concludes that HSRDs represent a considerable proportion of disease burden, reflecting the growing need for training in trichology, especially for dermatologists working in ambulatory outpatient care.

      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.
