This study was conducted to test whether ginsenoside F2 can reduce hair loss by influencing sterol regulatory element-binding protein (SREBP) cleavage-activating protein (SCAP) and the transforming growth factor beta (TGF-β) pathway of apoptosis in dihydrotestosterone (DHT)-treated hair cells and in a DHT-induced hair loss model in mice. Results for ginsenoside F2 were compared with finasteride...

OBJECTIVES Gentamicin (GM) is a commonly used aminoglycoside antibiotic that generates free oxygen radicals within the inner ear, which can cause vestibulo-cochlear toxicity and permanent damage to the sensory hair cells and neurons. Piper longum L. (PL) is a well-known spice and traditional medicine in Asia and Pacific islands, which has been reported to exhibit a wide spectrum of activity, in...

UNLABELLED Platelet-rich plasma (PRP) has emerged as a new treatment modality in regenerative plastic surgery, and preliminary evidence suggests that it might have a beneficial role in hair regrowth. Here, we report the results of a randomized, evaluator-blinded, placebo-controlled, half-head group study to compare, with the aid of computerized trichograms, hair regrowth with PRP versus placebo...

OBJECTIVE To study the long-term outcome of adverse effects reported by persons who used a commercial hair-straightening product known as the Rio Hair Naturalizer System (World Rio Corporation). DESIGN Survey of individuals who contacted the Food and Drug Administration in 1994 and 1995 to report adverse effects linked to using the product. SETTING Persons residing in the United States. P...

Hair follicles (HF) undergo precisely regulated recurrent cycles of growth, cessation, and rest. The transitions from anagen (growth), to catagen (regression), to telogen (rest) involve a physiological involution of the HF. This process is likely coordinated by a variety of mechanisms including apoptosis and loss of growth factor signaling. However, the precise molecular mechanisms underlying f...

Background: Alopecia Areate (AA) is a recurrent non-scarring patchy hair loss of autoimmune origin in a genetically susceptible individual although environmental factors may be contributory. The aim of this study is to evaluate serum iron and ferritin levels in patients with AA. Methods: Fifty patients of AA and 50 age and sex matched control subjects without any hair loss were studied. Results...

Background: Alopecia Areata (AA) is a non-scarring, autoimmune disorder which causes hair loss. Inflammatory reactions are involved in hair loss of the scalp and/or body. The involvement of chemokine receptors in the pathogenesis of AA is well defined among which, CXCL1 acts on neutrophils and CXCL9, CXCL10 and CXCL12 and serve as T lymphocytes recruiters. Objective: To study the serum levels o...

Seventeen patients with polycystic ovarian disease (peOD) were treated by laparoscopic ovarian electrocauterization (LEC). Ten were admitted to hospital for infertility, four for hirsutism, two for severe scalp hair loss, and one for abnormal uterine bleeding. Four of the patients were virgins. We had 50% (5 of 10) pregnancies and 88% (15 of 17) showing a decline in testosterone levels aft...

We report a series of experiments investigating the kinetics of hair cell loss in lateral line neuromasts of zebrafish larvae following exposure to aminoglycoside antibiotics. Comparisons of the rate of hair cell loss and the differential effects of acute versus chronic exposure to gentamicin and neomycin revealed markedly different results. Neomycin induced rapid and dramatic concentration-dep...

BACKGROUND Office physicians are unable to measure hair quantity, hair loss, and hair growth in a simple and meaningful manner. One solution is to measure the cross-sectional area of a bundle of hair that is growing within a premeasured cross-section of scalp. OBJECTIVE The objective was to design a mechanical device that precisely measures the cross-sectional area of a bundle of hair and des...
