Hair and scalp‐related disorders are a trending topic in dermatology, with a significant increase in number of consultations in the last decade

Hair and scalprelated disorders (HSRDs) seem to be a trending topic among dermatologists. Trichology is a field of dermatology that is currently experiencing a rise in the number of patients consulting, research and teaching. Hair is a cause for concern in the society, affecting all kinds of people. The dermatology community has the perception that more and more patients are consulting for hair loss, a fact that has been accentuated during and after the COVID19 pandemic. There must be several reasons for this increase. Some alopecias have undoubtedly increased their incidence, such as frontal fibrosing alopecia. In other forms of alopecia, it remains to be clarified whether we are experiencing a real increase in incidence or whether patients are consulting more when they learn that new therapies are available. With respect to research, the number of scientific publications related to trichology has almost doubled in the last decade: 1456 in 2011, compared with 2780 in 2021, according to PubMed data (Figure 1). In addition, several new therapies for different types of alopecia have emerged in recent years: lowdose oral minoxidil, plateletrich plasma, oral dutasteride, mesotherapy with dutasteride or topical finasteride for androgenetic alopecia, JAK inhibitors for alopecia areata, etc. Regarding teaching activities, in recent years, the training offer in trichology for dermatologists has increased, with the development of masters in trichology, stays in research centres and courses of scientific societies. Examples of these teaching activities include the European Academy of Dermatology courses about trichoscopy by Dr. Rudnicka and hair diseases by Dr. Piraccini (more info: https://eadv.org/ educa tion/facetoface) or the webinars of the European Hair Research Society (more info: https://ehrs.org/). In our dermatological environment, there is a growing interest for training in trichology even from the residency period itself. The excellent article of Lyakhovitsky et al. provides valuable information on the frequency of HSRDs at a tertiary dermatology outpatient clinic in Israel over a 10year period (2010– 2020). Interestingly, they showed that the annual number of HSRDs and their proportion with all dermatological outpatient visits have significantly increased from 1.24% in 2010 to 9.44% in 2020. There was a growing predominance of women with an average femaletomale Received: 8 November 2022 | Accepted: 8 November 2022
