BACKGROUND: Androgenetic alopecia (AGA) is a patterned hair loss occurring due to systemic androgen and genetic factors. It is the most common cause of hair loss in both genders. In recent years, many studies investigating the relation between systemic diseases and androgenetic alopecia presented controversial results. OBJECTIVES: In this study we aimed to investigate the frequency of androgenetic alopecia, the presence of accompanying systemic diseases, the relation between body mass index and androgenetic alopecia severity and the association of hyperandrogenemia signs with androgenetic alopecia in patients who referred to our outpatient clinic...

INTRODUCTION: In medical terms, alopecia is considered a relatively mild dermatological condition that nevertheless is a serious condition, but it causes major depression in many sufferers. Alopecia areata (AA) and androgenetic alopecia (AGA) are the main types of hair loss. This study assessed the quality of life (QoL) of Chinese patients with AA and AGA using the Dermatology Life Quality Index (DLQI) questionnaire. METHODS: A total of 178 AA and AGA patients were enrolled in this study, and DLQI was used to evaluate the QoL of the patients...

BACKGROUND: The side effects of mesotherapy for treatment of various forms of alopecia are often underreported, while scientific data for its efficacy are severely lacking. OBJECTIVE: To demonstrate the late onset side effects of mesotherapy for alopecia. METHODS: Three patients with androgenetic alopecia showed hair loss after previously uneventful mesotherapy sessions up to 1 year. RESULTS: Clinical, dermoscopic, and histopathological findings suggested an inflammatory scaring process at sites of mesotherapy injections...

BACKGROUND: Androgenetic alopecia (AGA) is the most common cause of alopecia in men. In the literature, although there are in vitro studies investigating the relationship between oxidative stress and AGA, any in vivo study does not exist. AIM: Our aim was to evaluate the oxidative stress status in male patients with early-onset AGA by measuring total oxidant levels (TOS), total antioxidant levels (TAS), and oxidative stress index (OSI). METHODS: Our study included 33 male patients with early-onset AGA and 30 healthy men between ages of 18 and 30 years old...

: Rationale:Androgenetic alopecia is not considered a life threatening disease but can have serious impacts on the patient's psychosocial life. Genetic, hormonal, and environmental factors are considered responsible for the presence of androgenetic alopecia. Recent literature reports have proved the presence of inflammation and also of oxidative stress at the level of dermal papilla cells of patients with androgenetic alopecia Objective:We have considered of interest to measure the oxidative stress parameters in the blood of patients with androgenetic alopecia Methods and results:27 patients with androgenetic alopecia and 25 age-matched controls were enrolled in the study...

Worldwide, more than 1.9 billion adults are overweight, and around 600 million people suffer from obesity. Similarly, ~382 million individuals live with diabetes, and 40-50% of the global population is labeled at "high risk" (i.e., prediabetes). The impact of these two chronic conditions relies not only on the burden of illnesses per se (i.e., associated increased morbidity and mortality), but also on their increased cost, burden of treatment, and decreased health-related quality of life. For this review a comprehensive search in several databases including PubMed (MEDLINE), Ovid EMBASE, Web of Science, and Scopus was conducted...

Civilizational progress initially contributes to the problem of hair loss and then to alopecia as regards both frequency and therapeutic dilemmas. The work presents trichological problems which occur more rarely, i.e. drug-induced, anagen and telogen alopecia, congenital and acquired structural hair disorders, psychic disturbances concerning the hair as well as the hair during menopause. Then, the article briefly describes contagious (infectious) diseases as well as diseases with inflammatory etiology which are accompanied by exfoliation and (frequently) pruritus...

Objective: Hair loss is a significant problem worldwide. The most common cause of hair loss in men is male androgenetic alopecia, male pattern baldness, which is primarily due to the presence of nonfunctional or dead hair follicles in the scalp. Hair follicular unit transplantation has been a widely used technique to transplant hair follicles into bald areas. Although follicular unit transplantation generally gives satisfactory hair transplantation, efforts have been made to further increase the efficacy of follicular unit transplantation in hair regeneration...

In androgenetic alopecia, androgens impair dermal papilla-induced hair follicle stem cell (HFSC) differentiation inhibiting Wnt signaling. Wnt agonists/antagonists balance was analyzed after dihydrotestosterone (DHT) stimulation in androgen-sensitive dermal papilla cells (DPC) cultured as spheroids or monolayer. In both culture conditions, DHT stimulation downregulated Wnt5a and Wnt10b mRNA while the Wnt antagonist Dkk-1 was upregulated. Notably, tissue architecture of DPC-spheroids lowers Dkk-1 and enhances Wnt agonists' basal expression; probably contributing to DPC inductivity...

BACKGROUND: Many studies have reported that androgenetic alopecia (AGA) might be a risk factor for cardiovascular disorders, and the association of AGA with dyslipidaemia has been studied. However, the results were controversial and previous meta-analyses had several critical limitations. OBJECTIVE: We performed a meta-analysis to clarify whether AGA patients have abnormal lipid profiles. METHODS: A literature search was performed using the MEDLINE, EMBASE, The Cochrane Library and KOREA MED databases...

BACKGROUND: Eccrine duct dilation (EDD) and syringoma-like sweat duct proliferation have been described as reactive changes occurring in a variety of skin conditions. However, extensive evaluation of EDD in scalp biopsies performed for alopecia has not been performed. METHODS: We retrospectively examined 129 cases of cicatricial alopecia (lichen planopilaris, central centrifugal cicatricial alopecia, and discoid lupus erythematosus) and 130 cases of noncicatricial alopecias (androgenetic alopecia, telogen effluvium, and alopecia areata) for the presence of EDD...
