Here, we present the case of a 16-year-old male who developed pityriasis amiantacea (PA) after the use of valproic acid. We propose that the keratinocyte proliferative activity of valproic acid mediated through the inhibition of glycogen synthase kinase-3β, and subsequent activation of the Wnt/β-catenin pathway could play a role in the development of PA. We additionally review the most relevant characteristics of this disease.

Hypotrichosis with juvenile macular dystrophy is a rare autosomal recessive disease, characterized by hypotrichosis and progressive macular degeneration, leading to blindness in the first three decades of life. It is associated with mutations in the cadherin 3 gene, resulting in the abnormal expression of P-cadherin. We report a case of a 4-year-old female patient diagnosed with this genodermatosis.

Aseptic and alopecic nodules of the scalp (AANS) are a rare and emerging entity in literature, etiology of which is presently unknown. It is characterized by multiple skin-colored dome-shaped nodules associated with nonscarring alopecia. It is usually located in the upper part of occiput and is surrounded by normal scalp. AANS have a good prognosis and can even resolve spontaneously. Only few cases have been reported in the literature so far. We are reporting a rare case of AANS in a 26-year-old female.

Postcast hypertrichosis is a common transient occurrence in orthopedic patients and generally resolves within a few months. Until now, two cases of localized hypertrichosis occurring on more than one pre-existing psoriatic lesions are reported in the literature. We describe the case of a patient who simultaneously developed a single psoriatic plaque and overlying localized hypertrichosis after plaster application. This concurrence is exceptional and may be explained by the expression of several growth factors and cytokines influencing both the hair cycle and the psoriatic inflammatory working...

Background: Hair tensile properties play a crucial role in cosmetology regarding functionality and quality. Commonly, scalp positions are subjected to varying magnitudes of environmental and physical stimuli and correspondingly different hair balding patterns are observed. Aim: This study is aimed at comparing the tensile properties of hair from four different scalp positions and quantifying the differences using statistical methods. Further, the second aim is to investigate the structure-property relationship with respect to the tensile properties obtained from hair in order to obtain a better understanding of the heterogeneous and composite structure of hair...

Background: Premature hair graying (PHG) is often a matter of great concern for patients as it is viewed as a sign of increasing age, debility, decreasing vigor, and may lead to low self-esteem and psychological morbidity. Its etiopathogenesis is not completely understood but genetic, and various acquired factors have been implicated. The present study was undertaken to evaluate various epidemiological and biochemical variables associated with PHG. Materials and Methods: A cross-sectional case-control study was conducted at a tertiary care hospital in North India for 1 year which comprised 120 patients and equal number of controls...

Context: Hair strength depends on integrity of protein structure, aging, and chemical effects and its exposure to mechanical (combing and curling) and thermal (hair drying and straightening) stimuli. Aims: The aim of this study is to correlate the mechanical properties such as tensile yield stress and tensile modulus of single hair fibers with thermal properties such as melting enthalpy and melting point obtained by differential scanning calorimetry. Materials and Methods: Single hair fibers covering seven decades of age were cut 2 cm above the scalp...

Premature graying of hair (PGH) is defined as graying of hair before the age of 20 years in Caucasians and before 30 years in African American population. It can severely affect the self-esteem of an individual. The exact etiopathogenesis remains unknown, although it has been associated with premature aging disorders, atopy, and autoimmune diseases. Patients, who present with PGH, should be assessed for syndromes and metabolism diseases. Hair dyes remain the main modality of the treatment for cosmetic concerns after nutritional supplementation...

A meta-analysis of published trials on the treatment of alopecia areata (AA) came to the conclusion that most have been reported poorly and so small that any important clinical benefits are inconclusive, and considering the possibility of spontaneous remission, especially for those in the early stages of the disease, the options of not being treated or depending on individual preference, and of wearing a wig may be alternative ways of dealing with the condition. And yet, from clinical practice, we know that depending on patient age, surface area, disease duration, and comorbidities an empiric treatment algorithm can be designed that is successful in a significant proportion of patients...

Lichen planopilaris (LPP) is an inflammatory hair disorder that is characterized by scarring hair loss, mostly affecting the vertex and parietal areas of the scalp. Frontal fibrosing alopecia (FFA) is considered a particular form of LPP, primarily affecting the hair follicles in the frontotemporal area of the scalp, with the hairline recession and eyebrow loss. There are case reports of FFA with concomitant involvement of facial vellus, characterized by roughening of the facial skin. We report five cases of facial vellus hair involvement in LPP, in the absence of other sites of disease activity...

Woolly hair nevus is a rarely acquired disorder of the scalp hair with well-circumscribed patch of curly and unruly hairs which are smaller in diameter than normal surrounding hair. We report a case of progressively evolving multiple woolly hair nevi in a 10-year-old child. Trichoscopy of unruly hairs showed abnormal kinking of hair shafts. Varying diameters of a single hair shaft, damaged cuticle, and trichorrhexis nodosa-like features were observed on hair microscopy. Histopathology showed abnormal bending of hair follicle above the hair bulb and irregularities of inner root sheath near the bulb at the bending...

Since Quinquaud's original report of folliculitis decalvans (FD), further clinical variants have been described on the basis of common histopathological and microbiological findings. Histopathology reveals a neutrophilic primary scarring alopecia, and microbiological studies invariably reveal pathogenic strains of Staphylococcus aureus . The presence of thickening of lesional skin in FD has been previously described. We report a new presentation of FD, clinically mimicking linear circumscribed scleroderma of the scalp...

Frontal fibrosing alopecia (FFA) represents a distinctive condition with a marginal scarring alopecia along the frontal and temporal hairline. Since its original description, the condition has been recognized to represent a more generalized than localized process, with extension beyond the frontotemporal hairline to include the parieto-occipital hairline and involve peculiar facial papules as evidence of facial vellus hair involvement and loss of peripheral body hair. Finally, the association of FFA with oral lichen planus, nail involvement, and concomitant lichen planopilaris (LPP) points to a close relationship to lichen planus...

We report a patient with frontal fibrosing alopecia (FFA), in whom autologous hair transplantation was successfully performed despite evidence of active disease. Since the underlying pathology of FFA is usually lichen planopilaris, reservations, and caveats have been expressed with respect to the risk of köbnerization phenomena following hair transplantation surgery. An important question that arises is how the lichenoid tissue reaction pattern is generated around the hair follicles in FFA. Follicles with some form of damage or malfunction might express cytokine profiles that attract inflammatory cells to assist in damage repair or in the initiation of apoptosis-mediated organ deletion...

Context: Frontal fibrosing alopecia (FFA) is a primary cicatricial alopecia characterized by progressive recession of frontal, and often temporoparietal, hairline mainly in postmenopausal women. Currently, there are no guidelines or proposed evidence-based treatment for FFA. Aims: The aim of this study was to retrospectively evaluate the effect and safety of intralesional triamcinolone acetonide injections (ITAIs) either as monotherapy or as concomitant treatment in the management of hairline recession in FFA...
