The hydraulic influence in androgen-related hair growth: implications in autoimmune disease.
Androgen-related changes in hair growth represent something of a mystery. Through the action of dihydrotestosterone (DHT), hair growth is increased in specific areas of the body. Elevated levels of DHT produce a general increase over the larger part of the body, often accompanied by hair loss in specific areas of the scalp. Because of this 'opposite' effect, a genetic difference in the hair follicles is proposed. This view is supported through the success of the 'plug graft' transplantation technique. However, this is unsatisfactory, because transplantation procedures that should work well according to this theory, ultimately fail. There is an alternative 'mechanism', that demonstrates its origins in the prime function of hair as an insulator. This simple mechanism makes sense of all the recognized effects of DHT in the dermal system, and throughout the body. In DHT-related hair growth it can be directly observed. The implication is that DHT achieves its effects through a primary physiological action that can be easily tested given the necessary expertise. Given existing knowledge, such a proven action of DHT would have serious implications for further understanding of female susceptibility to autoimmune disease.

An endocrinopathy characterized by dysfunction of the pituitary-adrenal axis and alopecia universalis: supporting the entity of a triple H syndrome.
We demonstrate the rare disorder of triple H syndrome in a 25-year-old man. He was pointed out as having short stature, at -5.9 s.d., and diagnosed as GH deficient at 6 years old. Approximately a year ago, he noticed systematic hair loss. He lost body weight by 7 kg during the last half year. He was admitted to Jichi Medical School Hospital because of unconsciousness. Physical findings showed disturbance of consciousness with Japan Coma Scale I-3. He had emaciation and alopecia universalis. Laboratory findings showed plasma glucose was as low as 1.11 mmol/l. GH and ACTH deficiency with hypoadrenocorticism were clarified. His intelligence was in the low normal range with a WAIS IQ of 70, and anterograde amnesia was suggested in the presence of a little, but not significant, morphological change in the hippocampus on a magnetic resonance imaging scan. Replacement by a physiological dose of hydrocortisone normalized plasma glucose, and restored body weight and growth of hair during the 7 month therapeutic period. The present finding strongly supports a clinical entity of triple H syndrome, including ACTH deficiency, alopecia universalis and anterograde amnesia, and that there may be some variation of the triad among the subjects.

A randomized clinical trial of 5% topical minoxidil versus 2% topical minoxidil and placebo in the treatment of androgenetic alopecia in men.
BACKGROUND: Topical minoxidil solution 2% stimulates new hair growth and helps stop the loss of hair in individuals with androgenetic alopecia (AGA). Results can be variable, and historical experience suggests that higher concentrations of topical minoxidil may enhance efficacy. OBJECTIVE: The purpose of this 48-week, double-blind, placebo-controlled, randomized, multicenter trial was to compare 5% topical minoxidil with 2% topical minoxidil and placebo in the treatment of men with AGA. METHODS: A total of 393 men (18-49 years old) with AGA applied 5% topical minoxidil solution (n = 157), 2% topical minoxidil solution (n = 158), or placebo (vehicle for 5% solution; n = 78) twice daily. Efficacy was evaluated by scalp target area hair counts and patient and investigator assessments of change in scalp coverage and benefit of treatment. RESULTS: After 48 weeks of therapy, 5% topical minoxidil was significantly superior to 2% topical minoxidil and placebo in terms of change from baseline in nonvellus hair count, patient rating of scalp coverage and treatment benefit, and investigator rating of scalp coverage. Hair count data indicate that response to treatment occurred earlier with 5% compared with 2% topical minoxidil. Additionally, data from a patient questionnaire on quality of life, global benefit, hair growth, and hair styling demonstrated that 5% topical minoxidil helped improve patients' psychosocial perceptions of hair loss. An increased occurrence of pruritus and local irritation was observed with 5% topical minoxidil compared with 2% topical minoxidil. CONCLUSION: In men with AGA, 5% topical minoxidil was clearly superior to 2% topical minoxidil and placebo in increasing hair regrowth, and the magnitude of its effect was marked (45% more hair regrowth than 2% topical minoxidil at week 48). Men who used 5% topical minoxidil also had an earlier response to treatment than those who used 2% topical minoxidil. Psychosocial perceptions of hair loss in men with AGA were also improved. Topical minoxidil (5% and 2%) was well tolerated by the men in this trial without evidence of systemic effects.

Nutritional factors and hair loss.
The literature reveals what little is known about nutritional factors and hair loss. What we do know emanates from studies in protein-energy malnutrition, starvation, and eating disorders. In otherwise healthy individuals, nutritional factors appear to play a role in subjects with persistent increased hair shedding. Hard, 40 years ago, demonstrated the importance of iron supplements in nonanaemic, iron-deficient women with hair loss. Serum ferritin concentrations provide a good assessment of an individual's iron status. Rushton et al. first published data showing that serum ferritin concentrations were a factor in female hair loss and, 10 years later, Kantor et al. confirmed this association. What level of serum ferritin to employ in subjects with increased hair shedding is yet to be definitively established but 70 micro g/L, with a normal erythrocyte sedimentation rate (< 10 mm/h), is recommended. The role of the essential amino acid, l-lysine in hair loss also appears to be important. Double-blind data confirmed the findings of an open study in women with increased hair shedding, where a significant proportion responded to l-lysine and iron therapy. There is no evidence to support the popular view that low serum zinc concentrations cause hair loss. Excessive intakes of nutritional supplements may actually cause hair loss and are not recommended in the absence of a proven deficiency. While nutritional factors affect the hair directly, one should not forget that they also affect the skin. In the management of subjects with hair loss, eliminating scaling problems is important as is good hair care advice and the need to explain fully the hair cycle. Many individuals reduced their shampooing frequency due to fear of losing more hair but this increases the amount seen in subsequent shampoos fuelling their fear of going bald and adversely affecting their quality of life.
Since hair growth is a complicated biological process, modern science has yet to grasp a complete picture. A number of traditional and alternative therapeutic methods that include drugs, surgery, and suppelements have been developed to help those who are losing hair. Unfortunately, none of these approaches are perfect for all hair loss problems due to the complexity of the phenomenon and diverse nature of the causes underlying hair loss. Also, most of chemical drugs and hair transplantation surgeries are accompanied by undesirable side effects.
DreamPharm offers Hair Million (have you heard?) to help treat hair loss problems. Numerous anecdotal cases have demonstrated that this herbal formula based on traditional Chinese herbs actually improves hair thinning and hair loss, a condition often associated with aging, for a significant fraction of people who take the formula regularly. It is not yet understood how Hair Million can stop hair loss and promote hair growth. No scientific research or placebo controlled clinical analysis has been performed on these herbs. Lack of scientific/clinical research is not uncommon in herbal arena. Nonetheless, there are two merits in this hair restoration herbal formula: Firstly, Hair Million is relatively inexpensive, and secondly, it is made of edible herbs that are known to be safe when consumed in regular quantities. Buy Propecia Online is a clinically tested prescription medication.
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.
