BACKGROUND: A new treatment for androgenetic alopecia (AGA) is 1,550-nm erbium-glass (Er:Glass) fractional laser. The wound healing process associated with this treatment is believed to be due to the stimulation of hair regrowth. Both the Wingless-related integration site (Wnt) proteins and insulin-like growth factor 1 (IGF-1) are important molecules that promote new hair growth. OBJECTIVE: The aim of this study was to evaluate the efficacy of 1,550-nm Er:Glass fractional laser treatment and determine the gene expression of IGF-1 and Wnt/β-catenin in patients with AGA...

BACKGROUND: Androgenetic alopecia (AGA) and alopecia areata (AA) are common causes of alopecia which can sometimes be difficult to differentiate clinically. Horizontal sections of scalp biopsies are used to study non-cicatricial alopecias due to the ability to perform both quantitative and morphometric analysis of hair follicles on them. METHODS: It was a prospective, cross-sectional study conducted to assess the utility of horizontal sections to differentiate between the alopecias...

Although the association of the psychological problems and androgenetic alopecia (AGA) gained the increasing attention, the psychosocial state in college students with AGA remains unknown. We recruited a total number of 355 college students with AGA from 18 universities in Southern China for interview. The Symptom Checklist-90-R (SCL-90-R) survey was used to assess the psychological state of these students. There were significant differences in somatization, obsessive-compulsive, interpersonal sensitivity, depression, phobic anxiety, psychoticism, and global severity index (GSI) between college students with AGA and the controls...

Although more than three decades have passed since the first use of minoxidil in androgenetic alopecia (AGA), its mechanisms of action have still not been comprehensively understood. 5α-reductase (5α-R) has an active role as the predominant enzyme in both AGA and female pattern hair loss (FPHL), which are also the main therapeutic indications of topical minoxidil. But there is insufficient literature data regarding the interaction of minoxidil and the enzyme 5α-R. Herein, we studied the in vitro expression levels of 5α-R type 2 (5α-R2) in a minoxidil-treated human keratinocyte cell line (HaCaT) in order to elucidate the relation of these two parameters...

Introduction: Minoxidil has been used topically to stimulate hair growth for male androgenetic alopecia (AGA) for more than 3 decades. It is currently being used for female AGA and alopecia areata (AA) as well. Although much time has passed since its first use, our understanding of its mechanism of action is highly limited. Therefore, we examined the inflammatory properties of AGA and AA, two entities in which minoxidil is being used as a therapeutic agent. We investigated the in vitro expression levels of cytokine interleukin-1 alpha (IL-1α), a potent inhibitor of hair growth, in minoxidil-treated human keratinocyte (HaCaT) cells to determine whether this molecule exerts anti-inflammatory effects...

Hair loss represents a condition that adversely affects the social life of patients. The most common cause is androgenetic alopecia (AGA), which is a genetically determined progressive hair-loss condition involving 5α-reductase. In this study, a novel anti-baldness agent based on Interconnected PolymerS TeChnology (IPSTiC), which is an effective strategy for the delivery of bioactive molecules, was developed. This product (IPSTiC patch hair) is based on a polymeric blend consisting of high molecular weight hyaluronic acid and soybean proteins and is able to improve efficacy and stability of bioactive ingredients such as Origanum vulgare leaf extract, Camellia Sinensis leaf extract, and Capsicum Annuum fruit extract...

BACKGROUND: Hair transplantation has enhanced the realm of procedural dermatology. Before the advent of follicular transplantation, androgenetic alopecia was a difficult disease to manage, as there is a limited armamentarium of topical and systemic pharmaceuticals. However, as with other novel surgical procedures, there is a steep learning curve, that may result in poor transplantation or cosmesis. CASE REPORT: We present a case of androgenetic alopecia, where previously, poorly implanted hairs were recycled by follicular unit extraction to increase hair density at the vertex of the scalp, which resulted in improved cosmesis and patient satisfaction...
