Steroidogenic isoenzymes in human hair and their potential role in androgenetic alopecia.
Androgenetic alopecia (AGA) is the most common type of hair loss. The relatively strong concordance of the degree of baldness in fathers and sons is not consistent with a simple Mendelian trait, and a polygenic basis is considered to be most likely. So far, the predisposing genes for AGA are unknown and we do not understand the molecular steps involved in androgen-dependent beard growth versus androgen-dependent hair loss, but AGA can be defined as a dihydrotestosterone (DHT)-dependent process with continuous miniaturization of sensitive hair follicles. The type 2 5alpha-reductase plays a central role by the intrafollicular conversion of testosterone to DHT. However, due to the increasing knowledge in this field, we now know that there are many more steroidogenic enzymes involved in the onset and development of AGA, and this article shall provide a critical overview of recent discoveries.

Idiopathic CD4+ T lymphocytopenia associated with disseminated flat warts and alopecia areata.
Idiopathic CD4+ T lymphocytopenia is a very rare condition characterized by persistent depletion of circulating CD4+ T lymphocytes, without evidence of HIV or HTLV infection, or other identifiable causes of immunodeficiency. The syndrome can present with dermatological diseases, including viral, fungal and bacterial infections, as well as Kaposi's sarcoma, epithelial cell malignancies, lymphoma and inflammatory dermatoses. We report the case of a 47-year-old woman with idiopathic CD4+ T lymphocytopenia who presented with a 10-year history of disseminated and refractory flat warts from which human papillomavirus type 3 DNA was identified. The patient also had alopecia areata.

The art of repair in surgical hair restoration part I: basic repair strategies.
BACKGROUND: An increasingly important part of many hair restoration practices is the correction of hair transplants that were performed using older, outdated methods, or the correction of hair transplants that have left disfiguring results. The skill and judgment involved in these repair procedures often exceed those needed to operate on patients who have had no prior surgery. The use of small grafts alone does not protect the patient from poor work. Errors in surgical and aesthetic judgment, performing procedures on noncandidate patients, and the failure to communicate successfully with patients about realistic expectations remain major problems. OBJECTIVE: This two-part series presents new insights into repair strategies and expands upon several techniques previously described in the hair restoration literature. The focus is on creative aesthetic solutions to solve the supply/demand limitations inherent in most repairs. This article is written to serve as a guide for surgeons who perform repairs in their daily practices. METHODS: The repairs are performed by excision with reimplantation and/or by camouflage. Follicular unit transplantation is used for the restorative aspects of the procedure. RESULTS: Using punch or linear excision techniques allows the surgeon to relocate poorly planted grafts to areas that are more appropriate. In special situations, removal of grafts without reimplantation can be accomplished using lasers or electrolysis. The key elements of camouflage include creating a deep zone of follicular units, angling grafts in their natural direction, and using forward and side weighting of grafts to increase the appearance of fullness. The available donor supply is limited by hair density, scalp laxity, and scar placement. CONCLUSION: Presented with significant cosmetic problems and severely limited donor reserves, the surgeon performing restorative hair transplantation work faces distinct challenges. Meticulous surgical techniques and optimal utilization of a limited hair supply will enable the surgeon to achieve the best possible cosmetic results for patients requiring repairs.

A method for evaluating and treating the temporal peak region in patients with male pattern baldness.
BACKGROUND: In the past, hair restoration surgeons have focused most of their attention and efforts on the reconstruction of the hairline region and the area on top of the head. However, little attention has been given to the temporal peaks and the areas immediately posterior to them. OBJECTIVE: The goals of this article are to describe the pattern baldness process at the temporal peaks and the region immediately posterior to them, and to describe a method for the evaluation and treatment of these very important and often neglected areas. METHODS: A method for evaluating and grading the temporal peak region is given. A surgical technique for treating this problem is described. This method consists of making 1.0 mm spear blade incisions at a very acute 10 degrees angle in the newly designed anterior peak and in between the hair follicles that remain in the area posterior to the peak. The grafting of the finest one-haired grafts available in between existing hair follicles is accomplished with the help of 3.5x expandable loupes. The anterior temporal peak design is coordinated with the position of the frontal hairline restoration; the more anterior the hairline, the more anterior the temporal peak and vice-versa. RESULTS: The results of evaluating the temporal peak areas and treating them appropriately have consistently restored the cosmetic harmony between the frontal hairline and the temporal peak region. It is important, however, to only utilize the finest hairs available to create an aesthetically pleasing result. CONCLUSION: When evaluating patients for hair restoration surgery, it should be a common practice to evaluate the temporal peak regions and the areas immediately posterior to them. These areas should be appropriately treated so that the frontal hair restoration coordinates with that of the temporal peak. The further anterior one comes with the hairline, the more anterior must come with the temporal peak restoration and vice-versa.
Seeing is believing. Learning by anecdotal observations is an old way of science.
It is not reasonable to stop taking daily food and herbal supplements altogether just because of scietific/clinical support: our life must go on until we have better understandings of food and herb. There are two merits that Hair Million enjoys: Firstly, Hair Million is relatively inexpensive, and secondly, it is made only of edible herbs that are known to be safe when consumed in regular quantities.
Propecia is a clincally validated prescription medication for hair loss.
DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones)
or estrogens (female hormones) in the cells.
Our bodies produce decreasing amount of DHEA as we get older.
various health benefits: To deter aging,
improve sexual function/erectile dysfunction, treat cognitive decline, enhance athletic performance,
facilitate weight loss, improve strength, prevent osteoporosis, enhance immunomodulation for rheumatic conditions,
and treat depression.
