Q: I read, with considerable interest, your excellent article on the latest in Dr. Angela Christiano’s work on follicular neogenesis. It seems to me that the next questions we should be asking are: when will testing begin on human subjects and when might her research develop into a hair cloning treatment that is available to the general public?

A: It is very difficult to determine when this phase of the research might begin and it is even harder to predict when treatment might become available. First, the technology is not quite there. Dr. Christiano showed in her recent paper that changing the environment of skin (fibroblast) cells so that they could form into 3-D cultures enabled them to induce human hair-follicle growth. Although this was a major step towards cloning hair, additional work needs to be done before we will be able to mass produce fully-functioning human hair follicles to the extent needed for hair transplantation.

In addition, research on human subjects requires that experiments meet rigorous federal regulatory standards and these take time to be approved and carried out. Supposing that further study of follicle neogenesis results in a breakthrough treatment for hair loss, this treatment would still require meeting substantial efficacy and safety requirements of the FDA before it would be made available to the public. We will be communicating important developments as they occur through our Hair Cloning Research section and through periodic updates in the Bernstein Medical Newsletter.
