“…10 Trichoscopy (hair and scalp dermoscopy) is a rapid in-office technique, which has become a standard procedure in differential diagnosis of hair loss. 11,13 However, there are no specific trichoscopy features that favor the diagnosis of LAHS. 14 The differential diagnosis includes alopecia areata (AA), trichotillomania, congenital hair shafts disorders and telogen effluvium (TE).…”

Background: Loose anagen hair syndrome (LAHS) is typically diagnosed in girls older than 2 years who present with hair that "will not grow". Hair microscopic examination shows absent inner and outer root sheaths, ruffling of the cuticle on the proximal hair shaft and deformed pigmented anagen bulbs.Objective: The aim of the study was to assess whether there are characteristic trichoscopic features favoring the diagnosis of LAHS. Patients and methods:Eighty nine children patients were included into the study (24 girls with LAHS, 25 with alopecia areata, 20 with telogen effluvium and 20 healthy children). In all groups trichoscopy was performed. Trichoscopy images were analyzed for abnormalities in the hairs shafts, the hair follicle openings and the interfollicular area.Results: Dirty dots were present in all groups. A unique feature of LAHS was the presence of rectangular black granular structures which differs from dense black dots seen in patients with alopecia areata. This feature was observed in 71% of patients with LAHS. Follicular units with single hairs constituted 92,9% of hair units in these patients (65,5% in telogen effluvium and 53% in the control group). Solitary yellow dots were found in 50% of patient with LAHS and in 24% of patients with alopecia areata, but was not found in control group or in patients with telogen effluvium. Conclusion:The trichoscopy features favoring the diagnosis of LAHS are: rectangular black granular structures, solitary yellow dots and major predominance of follicular units with single hairs.

“…One of the major developments was employing imaging techniques, especially hair and scalp dermoscopy (trichoscopy) in dermatological practice. 28,29,30 Trichoscopy allows in vivo visualization of hair and scalp structures at optical magnifications ranging up to 70-fold and more. Characteristic trichoscopy features of various hair and scalp diseases have been described.…”

Background: Reflectance confocal laser scanning microscopy (R-CSLM) is a new diagnostic technique which allows visualization of "optical intersections" within the epidermis and superficial layers of the dermis. Outlines of cells and their architecture are imaged and may be analyzed both horizontally and vertically to the skin surface. The method proved useful in early melanoma detection. We evaluated the potential usefulness of this method in a short series of patients with hair diseases.Main observations: Two healthy persons and 6 patients with hair diseases (1 with alopecia areata, 1 with androgenic alopecia and 4 with genetic hair shaft abnormalities) were examined with the use of Vivascope 1500. In all patients one scalp location and one location in the mid forearm were evaluated. R-CSLM examination gave in all cases high quality images of the hair shaft intersections, at 1μm intervals, which allowed detailed analysis of the hair structure. Hair follicles could be partly visualized at a depth of up to 200μm, which allowed analysis of only superficial parts of the hair follicles. An additional hurdle was bright reflection within the follicular ostia, which decreased the perception of details in these images.Hair could be best visualized, when analyzed on flat surfaces. Receiving good quality images from convex surfaces on the scalp required additional effort from the patient (to not move) and from the physician (to obtain best possible fit of the "optic window" to the scalp).Conclusions: These preliminary data show that R-CSLM may develop into a valuable tool in evaluation of hair shaft diseases. Further development is needed to apply this technique in abnormalities of the hair follicle and the perifollicular area.

“…Evaluations can be categorized as invasive (e g, scalp biopsies), semi-invasive (e g, trichogram), or noninvasive (e g, hair counts, microscopic evaluation, trichoscopy). Each of these approaches, when interpreted with the comprehensive clinical picture, can provide valuable insights into patient diagnosis, treatment and monitoring 7 .More recent studies have accumulated evidence that use of dermoscopy of hair and scalp (trichoscopy) in the clinical evaluation of hair disorders improves diagnostic capability beyond simple clinical inspection [8][9][10][11] . Without treatment, AGA takes a chronic progressive course with an average hair loss of 5-6 % annually with great inter individual variability 12,13 .…”

Background: Androgenetic alopecia (AGA) more commonly known as male pattern baldness affects up to 50% of men worldwide. Tretinoin prolongs anagen phase and increases percutaneous absorption of minoxidil three fold. Azelaic acid is an inhibitor of 5 alpha reductase and could be an effective agent in the treatment of androgen related pathology of human skin. Aims and Objective: 1) To study the efficacy of topical minoxidil 5% in treatment of androgenetic alopecia. 2) To study the efficacy of combination of topical minoxidil 5%, topical azelaic acid 1.5% and topical tretinoin 0.01% in treatment of androgenetic alopecia. 3) To compare the efficacy of foresaid topical preparation in treatment of androgenetic alopecia Setting: Outpatient department of Dermatology, Venerology Leprology of a tertiary health care centre with an attached medical college. Material and methods: Topical minoxidil 5 % lotion was used in 23 (50%) patients of the present study. Combination of topical minoxidil 5%, azelaic acid 1.5 % and tretinoin 0.01 % lotion was used in 23 (50 %) patients of the present study. Statistical analysis used: Epi info version 7. Results: There was statistically significant increase in hair number and thickness after treatment in both the groups. The comparison of the increase of hair number and thickness was statistically insignificant. Conclusions: Topical Minoxidil 5% is equally effective to combination of topical Minoxidil 5%, azelaic acid 1.5% and tretinoin 0.01% in treatment of androgenetic alopecia.
