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.

Female pattern hair loss.
Female pattern hair loss is a common condition characterized by a diffuse reduction in hair density over the crown and frontal scalp with retention of the frontal hairline. The prevalence increases with advancing age. It has been widely thought to be the female counterpart of male balding and is often referred to as female androgenetic alopecia. However, the role of androgens is not fully established. Scalp hair loss is undoubtedly a feature of hyperandrogenism in women but many women with female pattern hair loss have no other clinical or biochemical evidence of androgen excess. Female pattern hair loss is probably a multifactorial genetically determined trait and it is possible that both androgen-dependent and androgen-independent mechanisms contribute to the phenotype. In managing patients with female pattern hair loss the physician should be aware that the adverse effects on quality of life can be quite severe and do not necessarily correlate with the objective degree of hair loss. The treatment options are currently limited but modest improvements in hair density are achievable in some women.

Hair loss in internal medical illnesses
Hair loss related to internal diseases is generally temporary and often fully reversible. An iron- or protein-deficiency induced hair loss may be cured by simple substitution. In acute internal diseases, fever and after operations the patient may expect complete recovery of the hair loss without therapy. Symptomatic alopecia due to chronic diseases has a different prognosis and is dependent on the severity and character of the underlaying disease. If the systemic disease can be cured the hair loss may be decreased. Treatment and diagnosis of the systemic disease is recommended to be performed in cooperation with experts of internal medicine, oncologists and specialists of endocrinology.

Retrospective evaluation of sex hormones and steroid hormone intermediates in dogs with alopecia.
The purpose of this study was to determine if there are specific steroid hormone aberrations associated with suspect endocrine alopecias in dogs in whom hypothyroidism and hyperadrenocorticism have been excluded. Steroid hormone panels submitted to the UTCVM endocrinology laboratory over a 7.5-year period (783 samples) from dogs with alopecia were reviewed. During this period, 276 dogs met the criteria for inclusion and were comprised of 54 different breeds. Approximately 73% of dogs had at least one baseline or post-ACTH stimulation steroid hormone intermediate greater than the normal range. The most frequent hormone elevation noted was for progesterone (57.6% of samples). When compared with normal dogs, oestradiol was significantly greater in Keeshond dogs and progesterone was significantly greater in Pomeranian and Siberian Husky dogs. Not all individual dogs had hormone abnormalities. Chow Chow, Samoyed and Malamute dogs had the greatest percentage of normal steroid hormone intermediates of the dogs in this study. Baseline cortisol concentrations were significantly correlated with progesterone, 17-hydroxyprogesterone (17-OHP) and androstenedione. Results of this study suggest that the pathomechanism of the alopecia, at least for some breeds, may not relate to steroid hormone intermediates and emphasizes the need for breed specific normals.
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.
