Background: Female androgenetic alopecia (FAGA) is a frequent cause of hair loss in women. Standard diagnostic methods are clinical inspection, pull test, and trichogram. It has been suggested that scalp dermoscopy (trichoscopy) revealing diversity of hair shaft diameter >20% is diagnostic of FAGA. Objective: To evaluate the value of trichoscopy as compared to the trichogram for the diagnosis of FAGA. Patients and Methods: Retrospective case study of 162 women with the complaint of hair loss who underwent trichoscopic examination and trichograms. Results: Of all women diagnosed FAGA (55%), 62% were diagnosed by trichogram, 72% by trichoscopy with a cut-off point of 20%, and 100% irrespective of the degree of diversity of hair shaft diameter. Conclusions: Trichoscopy is a valuable and superior method to the trichogram for diagnosis of FAGA, especially in early cases, with the highest yield irrespective of the suggested cut-off of 20% diversity of hair shaft.

Madarosis is a terminology that refers to loss of eyebrows or eyelashes. This clinical sign occurs in various diseases ranging from local dermatological disorders to complex systemic diseases. Madarosis can be scarring or non-scarring depending upon the etiology. Appropriate diagnosis is essential for management. Follicular unit transplantation has been found to be a useful method of treating scarring madarosis and the procedure relevant to eyebrow and eyelash reconstruction has been discussed. A useful clinical approach to madarosis has also been included for bedside diagnosis. The literature search was conducted with Pubmed, Medline, and Google scholar using the keywords madarosis, eyebrow loss, and eyelash loss for articles from 1960 to September 2011. Relevant material was also searched in textbooks and used wherever appropriate.

Background: Female pattern hair loss (FPHL) is a progressive hair loss disorder with unclear triggering and supporting factors. Trichoscopic features of each stage of FPHL have not been specifically elaborated previously. Aims: To analyze characteristics and investigate associations of clinico-laboratory and trichoscopic features of female patients in regard to the severity of hair loss in FPHL and to facilitate its diagnosis using noninvasive scalp dermoscopy (trichoscopy) in Fitzpatrick skin type III patients. Materials and Methods: Clinico-laboratory and trichoscopic data from 60 patients with FPHL were analyzed using Spearman's correlation test. Results: Patients had mean age of 34.4±10.6 years and mean duration of hair loss of 4.49±3.76 years. Of all, 45% (27/60) had a family history of pattern hair loss (PHL) and had an earlier onset of hair loss. Stage of hair loss positively correlated with duration and age at presentation. No association was found between the severity of FPHL and laboratory values including anemic and gonadal hormone profiles. Characteristic trichoscopic features (at 10-fold magnification) of FPHL were peripilar signs (PPS) (brown, BPPS and white, WPPS), white dots, scalp pigmentation, and focal atrichia. WPPS, scalp pigmentation, and focal atrichia positively correlated with the stage and duration of hair loss. Conclusions: Family history of PHL causes an earlier onset of hair loss but does not influence its course or severity. The latter is also not affected by abnormal anemic profile or hormonal levels. PPS, scalp pigmentation, focal atrichia, and white dots are characteristic of PHL. WPPS, scalp pigmentation, and focal atrichia reflect advanced PHL.

Dermoscopy has become an integral part of diagnosing scalp disorders including discoid lupus erythematosus (DLE). Follicular keratotic plugs are a marker of DLE and correlate with the hyperkeratosis and plugging of the follicular ostia with keratotic material. They may be present in acute or chronic lesions and their presence alone or in conjunction with other described dermoscopic features can lead to timely diagnosis and initiation of treatment. We present three cases of scalp DLE and discuss the clinical, dermoscopic and histopathologic features.

Woolly hair nevus is a rare non-hereditary focal condition characterized by unruly and tightly coiled hair. It can appear in childhood or adolescence and may be associated with epidermal or melanocytic nevus. Patients presenting with woolly hair must be examined completely to rule out cardiofaciocutaneous and Noonan syndrome.

Brooke-Spiegler syndrome (BSS) is a rare autosomal dominant disorder characterized by the presence of various adnexal tumors including multiple cylindromas, trichoepitheliomas and spiradenomas. A 35-year-old female presented with multiple asymptomatic nodular lesions over face and scalp since the age of 5 years. There were no complaints suggestive of systemic involvement. Her son, elder sister, younger sister, father, father's sister, and grandmother had history of similar lesions. On examination, there were multiple asymptomatic skin-colored firm papulonodular lesions measuring from 2 to 8 mm in diameter, with smooth surface mainly affecting central part of face. Scalp showed pinkish, firm, smooth-surfaced, dome-shaped nodules measuring about 1 to 3 cm in size. Histopathological examination was consistent with trichoepitheliomas for the facial lesions and cylindromas for the scalp lesions. The diagnosis of BSS was thus confirmed.

We report a ten-month-old male infant, presenting with congenital hypotrichosis of scalp, absence of eyebrows and eyelashes. He also had multiple milia over face and extremities along with palmoplantar pits. The infant was born to third degree consanguineous marriage. None of the family members had similar disease. Histopathology was consistent with milia. Based on these findings, a diagnosis of unclassified ectodermal dysplasia was made.

Trichotillomania is characterized by the repeated urge to pull out hair, leading to noticeable hair loss, distress, and social or functional impairment. Most of the cases present initially to dermatologists with complaints of loss of hair and is often confused with other dermatological conditions like alopecia areata, tinea capitis, traction alopecia, and loose anagen syndrome. It is a chronic condition and difficult to treat. No formal treatment algorithm is present for trichotillomania and no drug has been found to be universally effective. We present a case report of a 22-year-old single female diagnosed with trichotillomania, with complaints of recurrent hair pulling resulting in noticeable hair loss since the age of 8 years. She was treated with Habit Reversal Training with Stimulus Control over a period of 12 weeks and attained complete remission. The effectiveness of HRT plus for the treatment of Trichotillomania is ascertained.
