Hormonal and metabolic abnormalities have been reported in men with early-onset androgenetic alopecia (AGA). Although this has been ascribed to the existence of a male polycystic ovary syndrome (PCOS)-equivalent, data on this topic are inconsistent and this syndrome has not been already acknowledged. To evaluate if, already before the age of 35 years, any difference occurs in the glycolipid and hormonal profiles and in the body weight in men with AGA compared to age-matched controls, we performed a comprehensive meta-analysis of all the available observational case-control studies of literature, using MEDLINE, Google Schoolar and Scopus databases...

Hair loss or alopecia is a common and distressing clinical complaint in the primary care setting and can arise from heterogeneous etiologies. In the pediatric population, hair loss often presents with patterns that are different from that of their adult counterparts. Given the psychosocial complications that may arise from pediatric alopecia, prompt diagnosis and management is particularly important. Common causes of alopecia in children and adolescents include alopecia areata, tinea capitis, androgenetic alopecia, traction alopecia, trichotillomania, hair cycle disturbances, and congenital alopecia conditions...

BACKGROUND: Platelet-rich plasma has shown beneficial effects in the treatment of androgenic alopecia with its growth factor properties in accelerating the dermal papilla. Dermoscopy is a noninvasive method that allows the in vivo evaluation of microstructures not visible to the naked eye. OBJECTIVE: To ascertain the role of platelet-rich plasma (PRP) with microneedling, and to compare the pre- and post-treatment dermoscopic features in androgenetic alopecia. (AGA)...

CONTEXT: There are very few studies evaluating efficacy of platelet-rich plasma (PRP) in hair restoration and its combination with microneedling. As far as ascertained, there is no study to evaluate efficacy of microneedling with PRP plus topical minoxidil (5%) versus topical minoxidil (5%) alone in androgenetic alopecia (AGA). AIMS: This study aims (1) to compare the efficacy of (a) topical minoxidil (5%) alone and (b) topical minoxidil (5%) + microneedling with PRP in men between 18 and 50 years with AGA Grade III to V vertex (Norwood-Hamilton scale) and (2) to perform objective and subjective evaluation based on clinical improvement and photographic evidence...

BACKGROUND: Hair follicles are known to contain a well-characterized niche for adult stem cells: the bulge, which contains epithelial and melanocytic stem cells. Stem cells in the hair bulge, a clearly demarcated structure within the lower permanent portion of hair follicles, can generate the interfollicular epidermis, hair follicle structures, and sebaceous glands. The bulge epithelial stem cells can also reconstitute in an artificial in vivo system to a new hair follicle. METHODS: In this study, we have developed a new method to isolate human adult stem cells by mechanical centrifugation of punch biopsy from human hair follicles without culture condition...

Mesotherapy (from Greek meso = in between, therapeia = treat) is a non-surgical, mostly cosmetic therapy, where active substances are injected intradermally into a depth of about 4 mm. It is an effective and easy-to-use method in the treatment of alopecia. It is effective both in the therapy of androgenetic alopecia and telogen effluvium. In recent years, it has been massively expanded also among non-medical fields, which has caused its contradictory perception by professional medical circles outside dermatologists...

Androgenetic alopecia is one of the most common diagnoses in a hair clinic. It is non-scarring pattern hair losses that affect individuals, independent on severity, age and gender. The incidence of AGA increases within the age. AGA affects women less frequently, is usually milder and is associated with diffuse thinning of the hair scalp. Prompt diagnosis and treatment are essential for obtaining optimal outcome.

The occurrence of a genetic background in the etiology of polycystic ovarian syndrome (PCOS) represents the rational basis to postulate the existence of a male PCOS equivalent. Hormonal and metabolic abnormalities have been described in male relatives of women with PCOS. These males also have a higher prevalence of early onset (<35 years) androgenetic alopecia (AGA). Hence, this feature has been proposed as a clinical sign of the male PCOS equivalent. Clinical evidence has shown that men with early onset AGA have hormonal and metabolic abnormalities...

From the beginning, artificial hair implantation has aroused a lot of interest, sometimes controversial, in the field of hair restoration. The artificial fiber must be of high quality and biocompatible. Biofibre® is a very fine fiber having diameter of 80 m. The standard length of this fiber is 15 or 30 cm, to satisfy multiple patient requests. They are available in 13 colors and 3 different shapes (straight, wavy and curly). Artificial hair implant is indicated in all (male and female) cases of androgenetic alopecia, especially for those who show dismal response to medical therapies and have poor donor area supply for hair transplantation...

BACKGROUND: Androgenic treatment of female-to-male transgender patients may result in androgenetic alopecia (AGA). Use of 5-alpha-reductase inhibitors are useful as oral treatment of AA in men. There are no previous studies of the use of finasteride in transgender men as treatment of AGA. AIM: To evaluate the effectiveness and safety of an oral 5α-reductase inhibitor (finasteride) for AA developed in transgender men. METHODS: This single-centre retrospective study enrolled female-to-male transgender patients with a clinical diagnosis of AGA to receive 1 mg of an oral type II 5α-reductase inhibitor for at least 12 months...

BACKGROUND: Patients who suffer from scars or wrinkles have several therapeutic options to improve the appearance of their skin. The available treatment modalities that provide desirable results are often overtly invasive and entail a risk of undesirable adverse effects. Microneedling has recently emerged as a non-ablative alternative for treating patients who are concerned with the aesthetic changes that result from injury, disease or ageing. OBJECTIVE: This review aims to evaluate the current evidence in the literature on microneedling...

Treatments for androgenetic alopecia constitute a multi-billion-dollar industry, however, currently available therapeutic options have variable efficacy. Consequently, in recent years small biotechnology companies and academic research laboratories have begun to investigate new or improved treatment methods. Research and development approaches include improved formulations and modes of application for current drugs, new drug development, development of cell-based treatments, and medical devices for modulation of hair growth...

BACKGROUND/AIMS: Androgenetic alopecia is an extremely common dermatological disorder affecting both men and women. Oral finasteride (FNS), a synthetic 4-aza-3-oxosteroid compound with poor aqueous solubility, blocks the peripheral conversion of testosterone to dihydrotestosterone (DHT) in a significant reduction in DHT concentration, achieving satisfactory results in alopecia treatment. However, its oral intake generally causes severe side effects. Considering that there is currently no scientifically proven treatment, new drug delivery systems able to improve alopecia therapy are urgently required...

Widespread expression of the transcription factor, nuclear factor (erythroid-derived 2)-like 2 (NRF2), which maintains redox homeostasis, has recently been identified in the hair follicle (HF). Small molecule activators of NRF2 may therefore be useful in the management of HF pathologies associated with redox imbalance, ranging from HF greying and HF ageing via androgenetic alopecia and alopecia areata to chemotherapy-induced hair loss. Indeed, NRF2 activation has been shown to prevent peroxide-induced hair growth inhibition...

In this study, we developed positively charged liquid crystalline nanoparticles (LCN) coated with chitosan (CHI) to enhance the skin permeation and distribution of 5α-reductase inhibitors for the treatment of androgenetic alopecia. LCN and surface-modified LCN (CHI-LCN) were prepared by ultrasonication method, and their physicochemical properties were characterized. In vitro and in vivo skin permeation and retention were studied using porcine abdominal skin and mice skin by using the Franz diffusion cell. Skin distribution and cellular uptake of LCN and CHI-LCN were also investigated...

Androgenetic alopecia (AGA) is a common form of scalp hair loss that affects up to 50% of males between 18-40 years old. Several molecules are commonly used for the treatment of AGA, acting on different steps of its pathogenesis (Minoxidil, Finasteride, Serenoa repens) and show some side effects. In literature, on the basis of hypertrichosis observed in patients treated with analogues of prostaglandin PGF2α, was supposed that prostaglandins would have an important role in the hair growth: PGE and PGF2α play a positive role, while PGD2 a negative one...

Androgenetic alopecia is the most common form of hair loss. Minoxidil has been approved for the treatment of hair loss, however its mechanism of action is still not fully clarified. In this study, we aimed to elucidate the effects of 5% minoxidil topical foam on gene expression and activation of signaling pathways in vertex and frontal scalp of men with androgenetic alopecia. We identified regional variations in gene expression and perturbed signaling pathways using in silico Pathway Activation Network Decomposition Analysis (iPANDA) before and after treatment with minoxidil...
