Indications for micrograft hair transplantation
Advances in treatment of androgenetic alopecia have led to the development of novel medical or surgical therapies adapted to the severity of hair loss and balding. Follicular units or tiny micro-graft hair transplants are a fundamental technical progress. This technique leads to the simple and painless permanent restoration of hair in male and female baldness. It provides the patient with a group of 1 to 3 hairs, emerging from a single orifice. The difference between androgenic receptors of occipital areas and those of other areas explains the permanent nature of the implanted hair growth. The degree of male or female androgenetic alopecia can be determined according to Hamilton's static classification or Ludwig's Classification, or it can be measured and monitored more accurately with Bouhanna's Dynamic Multifactorial Classification. The current indications for micro-graft transplantation are

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.

Lupus panniculitis clinically simulating alopecia areata.
A 27-year-old woman with a known history of lupus erythematosus presented with two circumscribed patches of non-scarring alopecia closely resembling alopecia areata. Scalp biopsy showed a predominantly subcutaneous and deep dermal lymphocytic infiltrate that surrounded the deep follicular segments and hair bulbs, as well as the eccrine glands. There was associated hyaline fat sclerosis. The epidermis, infundibular and isthmus segments of follicles were relatively spared and lacked the lichenoid inflammation and fibrosis seen with lupus erythematosus. The biopsy findings illustrate that the deep variant of lupus panniculitis may be concentrated around the hair bulbs and deep temporary segments of hair follicles and spare the permanent stem cell-rich follicular segments. This pattern is capable of producing a temporary hair-loss, clinically simulating alopecia areata. The clinical history, presence of subtle erythema and scalp tenderness on physical examination, as well as the biopsy findings, were important clues in distinguishing our case from a true combination of alopecia areata and lupus erythematosus.

Molecular mechanisms regulating hair follicle development.
Clinical conditions causing hair loss, such as androgenetic alopecia, alopecia areata, and scarring alopecia, can be psychologically devastating to individuals and are the target of a multimillion dollar pharmaceutical industry. The importance of the hair follicle in skin biology, however, does not rest solely with its ability to produce hair. Hair follicles are self-renewing and contain reservoirs of multipotent stem cells that are capable of regenerating the epidermis and are thought to be utilized in wound healing. Hair follicles are also the sites of origin of many neoplasias, including some basal cell carcinomas and pilomatricoma. These diseases result from inappropriate activation of signaling pathways that regulate hair follicle morphogenesis. Identification of the signaling molecules and pathways operating in developing and postnatal, cycling, hair follicles is therefore vital to our understanding of pathogenic states in the skin and may ultimately permit the development of novel therapies for skin tumors as well as for hair loss disease. The purpose of this review is to summarize recent progress in our understanding of the molecular mechanisms regulating hair follicle formation, and to discuss ways in which this information may eventually be utilized in the clinic.
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.
