“…In TTM, proximal hair residues of different lengths are present in every field of view (19). A summary of the key features, which allow us to distinguish between TTM and AA in trichoscopy, are shown in Table SIII 1 . Our findings in tinea capitis included comma hairs, which are a trichoscopic hallmark of the disease (33)(34)(35)(36). Comma hairs seem to be specifically associated with dermatophyte-induced fungal scalp infections.…”

Differential diagnosis of trichotillomania is often difficult in clinical practice. Trichoscopy (hair and scalp dermoscopy) effectively supports differential diagnosis of various hair and scalp diseases. The aim of this study was to assess the usefulness of trichoscopy in diagnosing trichotillomania. The study included 370 patients (44 with trichotillomania, 314 with alopecia areata and 12 with tinea capitis). Statistical analysis revealed that the main and most characteristic trichoscopic findings of trichotillomania are: irregularly broken hairs (44/44; 100% of patients), v-sign (24/44; 57%), flame hairs (11/44; 25%), hair powder (7/44; 16%) and coiled hairs (17/44; 39%). Flame hairs, v-sign, tulip hairs, and hair powder were newly identified in this study. In conclusion, we describe here specific trichoscopy features, which may be applied in quick, non-invasive, in-office differential diagnosis of trichotillomania.

“…In tinea capitis fractured and slightly curved hair shafts, that resemble a comma at dermoscopic examination, zig-zag-hairs and corkscrew hairs (in patients of African descent) are characteristic feature of dermatophyte infection. 3,4,5 Furthermore in a recent case report the authors showed that hair trichoscopy features of tinea capitis in a patient disappeared with successful therapy and hair regrowth. 13 In veterinary dermatology, screening tests for dermatophytosis include Wood's-lamp examination and direct microscopic examination of the fluorescent hairs.…”

“…2 For example, although microscopic examination of infected hairs and fungal culture are considered the gold standard for diagnosis of tinea capitis in humans, dermoscopy of hair has been demonstrated to assist in the initial clinical diagnosis. 3 Indeed, slightly curved, fractured hair shafts, that resemble a comma at dermoscopic examination have been reported as a characteristic feature of both endothrix and ectothrix tinea capitis due to Microsporum canis and Trichopyton tonsurans infection.…”

Background -Dermoscopy is a non invasive technique allowing rapid and magnified in vivo observation of the skin and structures that lie beneath the skin surface. Various congenital and acquired hair shaft abnormalities may be also evaluated by dermoscopy and characteristic features of Microsporum canis-induced tinea capitis and trichotillomania in people have also been reported. Objectives -To describe the dermoscopic findings observed in cats with patchy alopecia due to Microsporum canis infection and in cats with self-inflicted hair loss. Animals -Twenty-four client-owned cats presented to a private veterinary referral practice. Methods -Dermoscopy was performed with both an handheld non-polarized light dermoscope at 10-fold magnification and a videodermoscope at 40-fold magnification. Results -At 10-fold magnification, the most characteristic findings observed in circumscribed lesions of cats with dermatophytosis were opaque, broken hairs slightly curved with an homogeneous thickness (comma-like structures) and a variable amount of brown-to-yellow greasy scales. In cats with self-induced alopecia, multiple hairs with a normal shaft suddenly and cleanly broken at different lengths, short tufts of hairs broken at equal level , hook-like and coiled hairs were observed. By videodermoscopy, hair shaft thickness was also measured. Conclusions -This observational descriptive study suggests that dermoscopy may represent an in vivo non-invasive technique helpful in differential diagnosis of patchy alopecia in cats.

“…Pediculosis capitis is a parasitic disease caused by an ectoparasite – the head louse. It is epidemic and involves intense pruritus and secondary skin lesions [25]. The therapeutic process of pediculosis capitis consists in several elements: topical treatment involving mechanical removal of nits, general treatment, prophylaxis and monitoring the patients’ surroundings [26, 27].…”

Civilizational progress initially contributes to the problem of hair loss and then to alopecia as regards both frequency and therapeutic dilemmas. The work presents trichological problems which occur more rarely, i.e. drug-induced, anagen and telogen alopecia, congenital and acquired structural hair disorders, psychic disturbances concerning the hair as well as the hair during menopause. Then, the article briefly describes contagious (infectious) diseases as well as diseases with inflammatory etiology which are accompanied by exfoliation and (frequently) pruritus. Finally, alopecia cicatricans is discussed. Alopecia areata and androgenetic alopecia are omitted herein because they occur more often and will be described in another work. Any disproportions and upset balance concerning correct functioning of mechanisms within the scalp hair system are the evidence of pathologies.
