Formononetin is one of the main components of red clover plants and its role on hair regrowth against hair loss has not been established yet. In the present study, we assessed the potential effects of formononetin on alopecia, along with impaired hair cycles by induction of apoptosis-regression.Depilated C57BL/6 mice were used for monitoring the hair cycles. Formononetin (1 and 100 µM) was topi...

We report the results of the Spanish and Portuguese working group (GEP) of the International Society for Forensic Genetics (ISFG) Collaborative Exercise 2002-2003 on mitochondrial DNA (mtDNA) analysis. Six different samples were submitted to the participating laboratories: four blood stains (M1-M2-M3-M4), one mixture blood sample (M5), and two hair shaft fragments (M6). Most of the labs reporte...
Because of its anti-androgenic activity spironolactone 50-200 mg daily is advocated widely for the management of female hirsutism but this practice lacks adequately controlled experimental support. In a double-blind placebo controlled study of the efficacy of spironolactone 100 mg daily in idiopathic hirsutism we were unable to demonstrate objective benefit from spironolactone treatment. The me...
OBJECTIVE To describe an organized diagnostic approach for both nonscarring and scarring alopecias to help family physicians establish an accurate in-office diagnosis. To explain when ancillary laboratory workup is necessary to confirm the diagnosis. QUALITY OF EVIDENCE Current diagnostic and therapeutic interventions for hair loss are based on randomized controlled studies, uncontrolled stud...
Traction folliculitis is a component of traction alopecia syndrome and has received minimal attention in primary source medical literature. The popularity of hairstyles that produce hair traction and the knowledge that early intervention improves prognosis amplify the importance of recognizing this entity. Traction folliculitis presents as perifollicular erythema and pustules on the scalp in ar...
A 45-year-old healthy female presented to the dermatologic clinic with a 6-month history of diffuse hair loss and thinning but no relevant medical or pharmacological history. Scalp examination showed low-density hair in a diffuse pattern, which was more pronounced in the parietal and frontal areas ( fig. 1 a). The pull test was positive. Scalp dermoscopy revealed hair-shaft thinning and a lot o...
We are frequently asked, what does hair analysis reveal about heavy metals? First, heavy metals are so ubiquitous in our environment that everyone is exposed to them. They cannot be avoided completely and are found in virtually everyone to some degree. Most clinician’s are aware that hair tissue mineral analysis (HTMA) measures nutritional minerals and the heavy metals that are incorporated int...
