Androgens and alopecia.
Androgens have profound effects on scalp and body hair in humans. Scalp hair grows constitutively in the absence of androgens, while body hair growth is dependent on the action of androgens. Androgenetic alopecia, referred to as male pattern hair loss (MPHL) in men and female pattern hair loss (FPHL) in women, is due to the progressive miniaturization of scalp hair. Observations in both eunuchs, who have low levels of testicular androgens, and males with genetic 5alpha-reductase (5alphaR) deficiency, who have low levels of dihydrotestosterone (DHT), implicate DHT as a key androgen in the pathogenesis of MPHL in men. The development of finasteride, a type 2-selective 5alphaR inhibitor, further advanced our understanding of the role of DHT in the pathophysiology of scalp alopecia. Controlled clinical trials with finasteride demonstrated improvements in scalp hair growth in treated men associated with reductions in scalp DHT content, and a trend towards reversal of scalp hair miniaturization was evident by histopathologic evaluation of scalp biopsies. In contrast to its beneficial effects in men, finasteride did not improve hair growth in postmenopausal women with FPHL. Histopathological evaluation of scalp biopsies confirmed that finasteride treatment produced no benefit on scalp hair in these women. These findings suggest that MPHL and FPHL are distinct clinical entities, with disparate pathophysiologies. Studies that elucidate the molecular mechanisms by which androgens regulate hair growth would provide greater understanding of these differences.

Gene array profiling and immunomodulation studies define a cell-mediated immune response underlying the pathogenesis of alopecia areata in a mouse model and humans.
Alopecia areata is a suspected autoimmune hair loss disease. In a rodent model, alopecia areata can be induced in normal haired C3H/HeJ mice by transfer of skin grafts from mice with spontaneous alopecia areata. At weeks 2, 4, 6, and 10 after surgery, grafted mice were euthanized, skin collected and processed for histology, and RNA extracted. Age-matched sham-grafted mice, and mice with and without spontaneous alopecia areata, were similarly processed. For comparison, skin biopsies from alopecia areata and androgenetic alopecia affected humans were also collected. Skin mRNA processed to cDNA was analyzed using Affymetrix mouse 11K and human 6800 gene chip(R) array technology. Microarray results indicated 42 known genes upregulated or downregulated during onset of mouse alopecia areata consistent with an inflammatory cell-mediated disease pathogenesis involving antigen presentation, costimulation, and a T helper 1 lymphocyte response. In contrast, 114 genes, many regulating immunoglobulin response, were altered late in disease development. In alopecia areata affected humans, 95 genes were significantly modulated. As confirmation of microarray analysis results, lymph node and spleen cells from alopecia areata affected mice injected into normal haired littermates transferred the alopecia areata phenotype. Alopecia areata onset could be inhibited in skin-grafted mice by modulation with B7.1- and B7.2-specific monoclonal antibodies. In addition, depletion of CD4+ CD8+ expressing cells in chronic alopecia areata affected mice using monoclonal antibodies permitted hair regrowth. The results consistently demonstrated the importance of an immune cell-mediated disease mechanism in alopecia areata pathogenesis and suggested targeting antigen-presenting cells and reactive lymphocytes may be effective in alopecia areata treatment.

Follicular unit extraction: minimally invasive surgery for hair transplantation.
BACKGROUND: Follicular Unit Transplantation (FUT) is performed using large numbers of naturally occuring individual follicular units obtained by single-strip harvesting and stereo-microscopic dissection. Donor wound scarring from strip excision, although an infrequent complication, still concerns enough patients that an alternative solution is warranted. OBJECTIVE: The purpose of this paper is to introduce Follicular Unit Extraction (The FOX Procedure), in which individual follicular units are removed directly from the donor region through very small punch excisions, and to describe a test (The FOX Test) that determines which patients are candidates for this procedure. This paper explores the nuances, limitations, and practical aspects of Follicular Unit Extraction (FUE). METHODS: FUE was performed using 1-mm punches to separate follicular units from the surrounding tissue down to the level of the mid dermis. This was followed by extraction of the follicular units with forceps. The FOX test was developed to determine which patients would be good candidates for the procedure. The test was performed on 200 patients. Representative patients who were FOX-positive and FOX-negative were studied histologically. RESULTS: The FOX Test can determine which patients are suitable candidates for FUE. Approximately 25% of the patients biopsied were ideal candidates for FUE and 35% of the patients biopsied were good candidates for extraction. CONCLUSION: FUE is a minimally invasive approach to hair transplantation that obviates the need for a linear donor incision. This technique can serve as an important alternative to traditional hair transplantation in certain patients.

Can stress make you lose your hair?
Many individuals are frightened by hair loss and are hesitant to speak about it. Many are unaware that stressors can causes hair loss and that hair care practices and habits can aggravate a hair loss situation. Intervention by the nurse in encouraging a person to have an adequate assessment and work-up can facilitate an accurate diagnosis. Supportive and appropriate therapy can then be arranged. The hair tells a story and can be associated with good health.
Herbs offer many help benefitting phytochemicals that have not yet been fully understood or appreciated by science.
Made of famous Chinese traditional herbs, Hair Million is a herbal hair restorati
on formula for hair loss problems.
Numerous anecdotal cases have demonstrated Hair Million's capability to actually improve the age-related
hair thinning and hair loss for a significant fraction of
people who take it diligently.
It is unknown how Hair Million stops hair loss, and promotes hair growth, despite all the anecdotal observations.
Neither scientific research nor placebo controlled clinical trials has been conducted due to the cost.
Shortage of scientific/clinical research is not uncommon in herbal/nutritional arena. However, it is not reasonable to stop taking daily food and herbal supplements altogether just because of scietific/clinical support:
our life must go on while we strive to better understand food and herb that we consume today.
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 they are consumed in regular quantities.
For scientifically proven prescription medication, try Propecia.

or estrogens (female hormones) in the cells.
