Study of gene expression alteration in male androgenetic alopecia: evidence of predominant molecular signaling pathways

Male androgenetic alopecia (AGA) is the most common form of hair loss in men and is characterized by a distinct pattern of progressive hair loss starting from the frontal area and the vertex of the scalp. Although several genetic risk loci have been identified, relevant genes for AGA remain to be defined.

Platelet-rich plasma for androgenetic alopecia: Does it work? Evidence from meta analysis

The use of platelet-rich plasma (PRP) has increased among different surgical specialities for the treatment of various conditions. Androgenetic alopecia is a common condition, with severe attendant psychosocial implications. PRP injections for hair restoration have become a popular practice among plastic surgeons. We performed a meta-analysis comparing local injection of platelet-rich plasma versus control to evaluate this issue in order to investigate the effectiveness of PRP local injections for androgenetic alopecia.

The importance of trichological examination in the diagnosis of alopecia areata

In this article we discuss the propedeutic aspects of alopecia areata, especially those found by dermatoscopy, an invaluable tool for diagnosis of the condition. Dermatoscopy facilitates the early detection of the characteristic changes in alopecia areata hair such as exclamation-point hairs, cadaverous hair, fuzzy hair, vellus type hair and yellow spots.

Anagen Effluvium Caused by Thallium Poisoning

Anagen effluvium is the abrupt loss of hair during the growth phase due to an insult that impairs mitotic or metabolic activity of the hair follicle. This form of hair loss is essentially synonymous with chemotherapy-induced alopecia. Less common causes include medications, radiation, toxic chemicals, andinflammatory disease. Thallium, once considered the “poisoner’spoison,” is anodorless, flavorless, colorless heavy metal and a rare cause of anagen effluvium.

Hair restoration surgery: challenges and solutions

Hair loss is a common problem affecting both men and women. The most frequent etiology is androgenetic alopecia, but other causes of hair loss such as trauma, various dermatologic diseases, and systemic diseases can cause alopecia. The loss of hair can have profound effects on one’s self esteem and emotional well-being, as one’s appearance plays a role in the work place and interpersonal relationships. It is therefore not surprising that means to remedy hair loss are widely sought. Hair transplant surgery has become increasingly popular, and the results that we are able to create today are quite remarkable, providing a natural appearance when the procedure is performed well. In spite of this, hair transplant surgery is not perfect. It is not perfect because the hair transplant surgeon is still faced with challenges that prevent the achievement of optimal results. Some of these challenges include a limit to donor hair availability, hair survival, and ways to conceal any evidence of a su ...

Androgenetic alopecia: a review

Purpose Androgenetic alopecia, commonly known as male pattern baldness, is the most common type of progressive hair loss disorder in men. The aim of this paper is to review recent advances in understanding the pathophysiology and molecular mechanism of androgenetic alopecia. Methods Using the PubMed database, we conducted a systematic review of the literature, selecting studies published from 1916 to 2016. Results The occurrence and development of androgenetic alopecia depends on the interaction of endocrine factors and genetic predisposition. Androgenetic alopecia is characterized by progressive hair follicular miniaturization, caused by the actions of androgens on the epithelial cells of genetically susceptible hair follicles in androgen-dependent areas. Although the exact pathogenesis of androgenetic alopecia remains to be clarified, research has shown that it is a polygenetic condition. Numerous studies have unequivocally identified two major genetic risk loci for androgen ...
