Treatment of hyperandrogenic alopecia in women.
OBJECTIVE: To determine the effectiveness of various antiandrogens for the treatment of premenopausal women with hyperandrogenic alopecia. DESIGN: Randomized, unmasked trial of three treatments in 36 hyperandrogenic women with alopecia and observation, without treatment, in 12 other similar patients. SETTING: Endocrinologic outpatient practice in Italy. PARTICIPANT(S): A total of 48 hyperandrogenic women with alopecia and 30 age- and weight-matched controls for the assessment of androgen levels. INTERVENTION(S): Randomization to cyproterone acetate (50 mg) with ethinyl estradiol (EE) in a reverse sequential regimen; flutamide (250 mg) or finasteride (5 mg) daily; all for 1 year. Twelve similar patients were observed without treatment for 1 year. MAIN OUTCOME MEASURE(S): Ludwig scores for hair thinning as well as patient and investigator assessments of treatment effectiveness. RESULT(S): Flutamide resulted in a reduction of 21% in Ludwig scores (2.3 +/- 0.2 to 1.8 +/- 0.1). The other treatment effects were not statistically significant. Patient and investigator assessments showed a similar trend. CONCLUSION(S): Flutamide at a dose of 250 mg daily induced a modest improvement in alopecia after 1 year, whereas cyproterone acetate and finasteride were not effective. Treatment for more than 1 year may be required for better results.

Kenogen. A new phase of the hair cycle?
BACKGROUND: A novel phenomenon has been described by the phototrichogram: the emptiness of the follicle after teloptosis. We called this phenomenon kenogen, from the Greek kappaepsilonnuovarsigma, 'empty'. OBJECTIVE: To describe the kenogen phase in its details. METHODS: Analysis of the existing literature. RESULTS: The original observation in 2 women was confirmed in 10 balding and non-balding males studied for 14 years in whom kenogen lasted about 4 months increasing up to about 7 months and affecting 80% of all hair cycles. In 2 women with progressing androgenetic alopecia studied for 2 years, kenogen involved 22% of the hair follicles, lasting from 3 months to 1 year. In a prepubertal boy studied for 1 year, it involved 8% of hairs and lasted about 2 months. CONCLUSION: During kenogen, the hair follicle rests physiologically, but duration and frequency are greater in androgenetic alopecia, possibly accounting for baldness. In addition to the classical cycle, the hair follicle may follow an alternative route during which the telogen phase, not accompanied by a coincident new early anagen, ends with teloptosis leaving the follicle empty.

Langerhans cells that express matrix metalloproteinase 9 increase in human dermis during sensitization to diphenylcyclopropenone in patients with alopecia areata.
BACKGROUND: We know little of the initial events during the sensitization phase of contact allergy in humans. Alopecia areata (AA), a disease of unknown pathogenesis characterized by patchy hair loss, may be treated by inducing contact allergy to diphenylcyclopropenone (DPC), later followed by its topical application. OBJECTIVES: To learn more about the initial events during sensitization in human skin, we studied the early events during induction of contact allergy to DPC in patients with AA. METHODS: DPC 2% and sodium lauryl sulphate (SLS) 4% were applied on the backs of eight patients with AA. Punch biopsies were taken 6 and 24 h after application. The biopsies were snap-frozen and cryostat sections were evaluated with immunohistochemistry using antibodies against CD1a, HLA-DR, CD3, CD54 and matrix metalloproteinase 9 (MMP-9). RESULTS: After 24 h all subjects exhibited erythema on the DPC-treated areas. Histological evaluation of biopsies from these areas showed hydropic degeneration and a significantly increased number of MMP-9+ cells in the dermis (P < 0.0005). The MMP-9+ cells were identified with double immunofluorescence staining as CD1a + Langerhans cells. The expression of the other markers studied remained unaltered irrespective of treatment, including treatment with SLS. CONCLUSIONS: Our findings show that DPC induces an irritant reaction leading to an increased number of MMP-9+ CD1a+ cells in the dermis during the initial phase of sensitization.

Psychological sequelae and alopecia among women with cancer.
PURPOSE: This article reviews the relevant literature on treatment-induced alopecia in women with cancer and describes the development of a computer-assisted intervention to reduce distress associated with this side effect. DESCRIPTION OF PROGRAM: Alopecia has been cited as the most disturbing anticipated side effect by up to 58% of women preparing for chemotherapy, with 8% being at risk for avoiding treatment. Women with cancer who experience alopecia as a side effect, compared with women with cancer and no alopecia, report lower self-esteem, poorer body image, and lower quality of life. Although physicians' recommendations are the most influential factor on cancer treatment choice, body image and effects on sexuality are the next most influential factors. A study of a computer-imaging intervention, based on concepts related to guided imagery and anticipatory grief, has been launched in an effort to aid women in coping with anticipated treatment-related alopecia. RESULTS: While we are still waiting for final data collection and analysis from the computer intervention study, the feedback thus far has been positive. CLINICAL IMPLICATIONS: The intervention described here may prove to be effective in desensitizing women with cancer to hair loss and facilitating an adjustment to self-acceptance. As such, a higher quality of life during the difficult time of coping may be maintained. The development of a computer-imaging intervention offers an opportunity to integrate a standard psychosocial intervention, personalized for each patient, into the routine patient care in the oncology setting.
Are you losing hair gradually or all of a sudden ? Hair Million is a herbal formula to address hair loss problems.
Numerous anecdotal cases demonstrate that this herbal formula based on Chinese herbs actually improves the age-related
hair thinning and hair loss for a significant fraction of people taking it regularly.
The biology of hair growth is complex and a field still in progress. We don't know how Hair Million stops hair loss,
and promotes hair restoration, 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. Hair Million is relatively inexpensive, and secondly, it is made only of traditional herbs that promote hair growth that are widely known to be safe in regular quantities.
For clinically tested prescription medication, check Propecia.
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.
