Most of the opposition to stem cells stem from the assumption that human embroys are required for stem cell production. However recent research indicates other viable sources (like placenta) of stem cells. The following appears to me a very promising avenue.
research published online by the Proceedings of the National Academy of Sciences provides new insight into the abilities of stem cells taken from hair follicles. The results indicate that these adult stem cells can develop into neurons.
The finding that the stem cells could form neurons and other cell types after transplantation in vivo as well as in a petri dish, the authors conclude, “raises possibilities of their therapeutic applications.” –Sarah Graham

Multipotent Stem Cells Identified in Hair Follicles; Hopes of Baldness CureOctober 8th, 2005 Research team led by Yann Barrandon at the EPFL (Ecole Polytechnique Federale de Lausanne) and the CHUV (Lausanne University Hospital) has discovered, using animal model, that certain cells (clonogenic keratinocytes) inside hair follicles are true multipotent stem cells, capable of developing into the many different cell types needed for hair growth and follicle replacement. They demonstrate that these holoclones can be used for long-term follicle renewal.
Stem Cell Therapy Raise Hope for Baldness Remedy May 17th, 2007 Mice with deep skin wounds can grow new hair, scientists said on Wednesday in a finding that offers hope for a baldness remedy for humans. The mice regenerated hair at the site of the wound via molecular processes similar to those used in embryonic development, according to the research, published in the journal Nature.
Baldness cure may lie in stem cellsJune 14th, 2009 MELBOURNE - It's time for people with receding hairline to cheer up - Australian scientists are trying to cure baldness by using stem cells to grow a potentially endless supply of new hair. If proved successful, cloning would overcome the limitations of existing hair-loss treatments.

Genetic study to hair fall successful; hopeful of stem cell therapy October 13th, 2008 Finally a reason for the bald people to smile. Nature Genetics journal professes some reasons why some people lose their hair, and how they may eventually be able to grow it back.
Multipotent Adult Stem Cells Discovered in Human Hair FolliclesJuly 13th, 2006 Researchers at the University of Pennsylvania School of Medicine have isolated a new source of adult stem cells that appear to have the potential to differentiate into several cell types. If their approach to growing these cells can be scaled up and proves to be safe and effective in animal and human studies, it could one day provide the tissue needed by an individual for treating a host of disorders, including peripheral nerve disease, Parkinson’s disease, and spinal cord injury.
Stem cells in hair follicles responsible for tissue regenerationFebruary 17th, 2009 How does the body regenerates organs? One of the nature's best-kept secret!
And who do we expect to uncover the mystery? Its our hair!!
The hair follicle, at the base of each hair strand is like a mini-dispensable organ. Throughout our lifetime each hair follicle follows a cycle of growth, destruction and rest using an intrinsic stem cell population.

And how would I have believed it without any biological evidences. I better appreciate your argument.
