BACKGROUND: Diffuse hair loss (DHL) is a common problem in adult women and has a major impact on quality of life. Ascertaining the etiological diagnosis is a challenging task in such patients. Satisfactory treatment can only be instituted after ascertaining the cause of hair loss. OBJECTIVE: To study the clinico-epidemiological profile of nonscarring DHL in females and to ascertain its underlying etiological factors. STUDY DESIGN: Of a total of 110 females, who presented with nonscarring DHL to the outpatient dermatology department, 100 qualified for inclusion in the study...

BACKGROUND: Considering the importance of hair in our modern society and the impact of hair loss, the efforts of researchers are addressed to better understand the mechanisms behind the hair cycle regulation and dysregulation. Because hair loss is multifactorial, differenced and new approaches are required. In particular we addressed our attention to two recently identified targets in hair cycling and growth control: olfactory receptor and autophagy. The aim of the study was to evaluate: the possible pro-autophagic effect of N1-methylspermidine (a spermidine analogue) in vitro and, in a double blind clinical trial, the safety and efficacy of topical daily application of a lotion containing N1-methylspermidine and Sandalore®...

Previous studies have shown that androgenic alopecia is associated with metabolic syndrome and diabetes. However, the detailed mechanism whereby diabetes causes alopecia still remains unclear. We focused on the inflammatory response that is caused by diabetes or obesity, given that inflammation is a risk factor for hair loss. Inducible nitric oxide synthase (iNOS) is known to be upregulated under conditions of acute or chronic inflammation. To clarify the potential role of iNOS in diabetes-related alopecia, we generated obese diabetic iNOS-deficient (ob/ob; iNOS-KO mice)...

Lupus erythemathosus is a chronic, relapsing disease with acute, subacute, and chronic lesions. Effluvium telogen occurs in the setting of systemic activity of the disease, and cicatricial alopecia results from discoid lesionsin on the scalp. Other types of alopecia, like alopecia areata, may rarely be found in lupus. Frontal fibrosing alopecia is characterized by frontotemporal hairline recession and eybrow loss. Histophatologically, it cannot be differentiated from lichen planopilaris.It is controversial whether frontal fibrosing alopecia is a subtype of lichen planopilaris...

Alopecia areata (AA) is an autoimmune non-scarring hair loss characterized by round patches on the scalp and body. It can progress to alopecia totalis (AT) where there is total loss of scalp hair and alopecia universalis (AU) in where hair loss encompasses the entire body. The pathophysiologic mechanism is unclear, but is thought to be due to peribulbar T-cell inflammation which results in premature induction of anagen follicles to catagen and telogen, without causing destruction of the hair follicle.

REVIEW
Andrey A Panteleyev
The secondary hair germ (SHG) - a transitory structure in the lower portion of the mouse telogen hair follicle (HF) - is directly involved in anagen induction and eventual HF regrowth. Some crucial aspects of SHG functioning and ontogenetic relations with other HF parts, however, remain undefined. According to recent evidence (in contrast to previous bulge-centric views), the SHG is the primary target of anagen-inducing signaling and a source of both the outer root sheath (ORS) and ascending HF layers during the initial (morphogenetic) anagen sub-phase...

Telogen effluvium is categorized in nonscarring alopecia, which shows scalp hair thinning and shedding diffusely resulting from inducing factors such as physiological stressful events and several acute or chronic diseases. It usually appears in female patients following parturition, as well as after febrile disease, major surgery, emotional stress, abrupt diet, chronic illness, or the taking of certain medication pills. Two patients who both recalled an operational history of hair transplantation visited our department with their frontal and both temporal hair loss...

BACKGROUND/OBJECTIVES: Short anagen syndrome is a hair cycle disorder usually diagnosed in early childhood and characterized by short hair length due to short duration of the anagen phase. The objective was to review the presentation and demographic characteristics of short anagen syndrome and compare them with the most common differential diagnosis, loose anagen syndrome. METHODS: A retrospective review of eight children with short anagen syndrome was performed at the University of Miami Outpatient Dermatology Clinic...

Minoxidil directly promotes hair growth via the stimulation of dermal papilla (DP) and epithelial cells. Alternatively, there is little evidence for indirect promotion of hair growth via stimulation of adipose-derived stem cells (ASCs). We investigated whether minoxidil stimulates ASCs and if increased growth factor secretion by ASCs facilitates minoxidil-induced hair growth. Telogen-to-anagen induction was examined in mice. Cultured DP cells and vibrissae hair follicle organ cultures were used to further examine the underlying mechanisms...

Androgenetic alopecia (AGA) is a hair loss disorder affecting 80% of men and 50% of women throughout their lifetime. Therapies for AGA are limited and there is no cure. There is a high demand for hair restoration. Platelet-rich plasma (PRP), a treatment modality shown to promote wound healing, has also been explored as a treatment for AGA. This literature review was conducted to assess the effectiveness of PRP treatment for AGA. Twelve studies conducted from 2011 to 2017 were evaluated and summarized by study characteristics, mode of preparation, and treatment protocols...

Insect wax is secreted by Ericerus pela Chavanness. It has been traditionally used to treat hair loss in China, but few reports have been published on the hair growth-promoting effect of insect wax. In this work, we examined the hair growth-promoting effects of insect wax on model animals. Different concentrations of insect wax were topically applied to the denuded backs of mice, and 5% minoxidil was applied topically as a positive control. We found that insect wax significantly promoted hair growth in a dose-dependent manner, 45% and 30% insect wax both induced hair to regrow, while less visible hair growth was observed in blank controls on the 16th day...

BACKGROUND: Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) represent 2 entities that cause primary cicatricial alopecia. These entities are clinically different; nevertheless, the literature suggests that FFA represents a form of LPP. The main argument in support of this hypothesis is that previous studies comparing the histologic findings have not found obvious differences between these diseases. METHODS: Our objective was to more critically compare and contrast 20 histologic findings of these diseases in a large number of patients in order to determine any significant histologic differences between LPP and FFA...

The application of next generation sequencing (NGS) for the analysis of mitochondrial (mt) DNA, short tandem repeats (STRs), and single nucleotide polymorphism (SNPs) has demonstrated great promise for challenging forensic specimens, such as degraded, limited, and mixed samples. Target enrichment using probe capture rather than PCR amplification offers advantages for analysis of degraded DNA since two intact PCR primer sites in the template DNA molecule are not required. Furthermore, NGS software programs can help remove PCR duplicates to determine initial template copy numbers of a shotgun library...

BACKGROUND: The growth of Inner Mongolian Cashmere goat skin hair follicle exhibits a periodic growth pattern. The hair growth cycle is distinguished as telogen, anagen, and catagen stages. The role of vimentin in the growth process of hair follicles is evident. To elucidate the mechanism underlying the vimentin activity in the growth cycle of hair follicles, transcriptome sequencing and liquid chromatography-tandem mass spectrometry were used to obtain the nucleic acid and amino acid sequences of VIIM gene and vimentin...

Even if minoxidil has been known for over 30 years as "hair growth stimulator" the precise mechanism of its action is not completely elucitated. Minoxidil shortens telogen, accelerates telogen-exogen phase and causes the premature entry of resting hair follicles into anagen phase. Moreover, minoxidil increases hair follicle size. A large part of hair treatment scientific literature confirms the efficacy of topically applied minoxidil in humans. In particular, patients treated with minoxidil showed a significant increase in "non vellus" hair count starting from baseline...

Throughout pregnancy, the body undergoes a variety of physiologic changes. The cutaneous findings can be most noticeable and often worrisome to both physicians and patients. Obstetricians and dermatologists must be able to differentiate between changes that are benign and those that may be pathologic. Most physicians recognize benign changes that are commonly described in literature such as hyperpigmentation, melasma, striae gravidarum, and telogen effluvium; however, they may be unaware of changes that tend to be less frequently discussed...
