Mineral content of hair is affected by season, breed, hair color within and between breeds, sire, age and body location. Seasonal effects may be due to stage of growth of hair and to changes caused by perspiration, surface contamination and diet. Breed and sire effects on mineral content of hair complicate prediction of nutritional status based on hair analyses because, in many commercial cattl...

In the field of consumer-used cosmetics for hair removal and hair growth reduction, there is a need for improved quantitative methods to enable the evaluation of efficacy and claim support. Optimized study designs and investigated endpoints are lacking to compare the efficacy of standard methods, like shaving or plucking, with new methods and products, such as depilating instruments or hair-gro...

Hair graying and hair loss are prominent and common characteristics of the elderly population. In some individuals these processes can significantly impact their quality of life, leading to depression, anxiety and other serious mental health problems. Accordingly, there has been much interest in understanding the complex physiological changes within the hair follicle in the aging individual. It...

Background: Cortisol is a crucial hormone for adaptation to challenging and stressful situations. Hair cortisol measurement used determine chronic stress; the growth rate of hair allows de...

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 ...

Multiple nutritional, environmental and lifestyle factors can directly affect hair follicles or weaken and make them sensitive to the action of androgens. Patients having hair fall, thinning and poor growth can be in early stages of androgenetic alopecia. Hair loss can be corrected and hair growth can be improved by addressing these nonandrogenic factors. Recent research has shown that androgen...

We analyzed changes of growth and apoptotic cell death in human hair follicles. In anagen hair follicles, terminal deoxynucleotidyltransferase-mediated deoxyuridine triphosphate-biotin nick labeling-positive cells were observed in the keratogenous zone of the upper bulb matrix, the inner root sheath, and the companion layer of the outer root sheath. DNA ladder formation was also detected in ana...

UNLABELLED Over the years, different kinds of hair transplantation have been compared in an attempt to overcome male pattern alopecia and, at the same time, maximize both the survival and growth rate of grafted hair. In this study, we have assessed the survival and growth rate of follicular units (FU) in an in vitro model, as compared with that of conventional hair micrografts, to experimentall...

Plants modify organ growth and tune morphogenesis in response to various endogenous and environmental cues. At the cellular level, organ growth is often adjusted by alterations in cell growth, but the molecular mechanisms underlying this control remain poorly understood. In this study, we identify the DNA BINDING WITH ONE FINGER (DOF)-type transcription regulator OBF BINDING PROTEIN4 (OBP4) as ...

An abnormal hair-growth cycle induces hair loss, which affects psychological distress and impairs life quality. Red ginseng marc (RGM) is usually discarded as a byproduct after extracting red ginseng, but several studies have shown that the RGM still has bioactive components including ginsenosides. Therefore, effects of fermented (fRGM) traditional polyherb formula (PH) were examined in C57BL/6...
