It has been a long while since skin surfaces and skin lesions have been examined by dermoscopy. However examining the hair and the scalp was done again recently and gained attention and slight popularity by the practical tool, namely trichoscopy, which can be called in a simplified way as a dermoscopy of the hair and the scalp. Trichoscopy is a great tool to examine and asses an active scalp disease and hair and other signs can be specific for some scalp and hair diseases. These signs include yellow dots, dystrophic hairs, cadaverized (black dots), white dots and exclamation mark hairs. Trichoscopy magnifies hair shafts at higher resolution to enable detailed examinations with measurements that a naked eye cannot distinguish nor see. Trichoscope is considered recently the newest frontier for the diagnosis of hair and scalp disease. Aim of this paper. The aim of this paper is to simplify and sum up the main trichoscopic readings and findings of hair and scalp disorders that are commonly encountered at clinic dermatology settings.

“…In active AA patients, the hallmark trichoscopic specific features were yellow dots, uniform cadaverized (black dots), dystrophic broken hair (micro-exclamation, tapered hairs which is a marker of active disease), trichoptilosis, pig tail, and short vellus hairs and upright re-growing hair [12][13][14] ( Figs. 8-11).…”

“…Dear Editor, An association of alopecia areata (AA) with other major forms of autoimmune diseases has been documented. [1][2][3][4][5] However, most of these studies are restricted by a small sample size, patient self-reported data or cross-sectional design. This study aimed to analyze the longitudinal risk of developing major autoimmune diseases, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), Hashimoto's thyroiditis, bullous pemphigoid, psoriasis and type 1 diabetes mellitus (DM) for patients with AA, using a retrospective cohort design.…”

“…Active (acute) AA can be distinguished from nonactive AA using trichoscopy. Features of disease activity include black dots, exclamation marks, broken hairs, trichoptilosis, pig tail, short vellus hairs,and upright regrowing hair whereas YD, WD, clustered WD, honeycomb pigmentation, black dotted pigmentation, and vellus hairs are markers of disease severity and inactive late stage disease [4,12,20,24,30,55,58]. In addition to this, disease activity showed negative relation with atypical red vessels in our study, we believed that these atypical red vessels indicated rejuvenation after the catabolic process in progressive AA [30].…”

Hair and scalp examination techniques can be classified into three categories: noninvasive methods (clinical history, general examination, photography, hair count, weighing shed hair, pull test, global hair counts, dermoscopy, electron microscopy, laser scanning microscopy, etc.); semi-invasive methods (the trichogram, unit areatrichogram); and invasive methods (biopsies in cicatritial alopecia). Scalp dermoscopy or trichoscopy is one of thenoninvasive techniques for the evaluation of patients with hair loss that allows for magnified visualization of the hair and scalp skin. It may be performed with a manual dermoscope (10× magnification) or a videodermoscope (up to 1000× magnification). This method is simple, quick, and easy to perform, is well-accepted by patients, and is useful for monitoring treatment, determining severity of the disease and follow-up. It is a simple, minimally invasive and rapid technique for measuring hair follicle activity. Trichogram represents a semi-invasive technique for the evaluation of patients with hair loss that allows the microscopic examination of hairs plucked from the scalp and provides information about the state of the proximal end of the hair shaft and the distal end. The trichogram is a useful complementary tool for clinical evaluation, diagnosis, and the monitoring of treatment response.
