Hair growth breakthrough offers hope to balding men and women

Researchers involved in a new study have discovered a breakthrough technique for growing human hair, offering hope to bald or balding men and women.

According to the researchers, they're moving close toward achieving the goal of the study, which is to clone hair cells and then replant them on the scalp in an effort to generate new hair growth.

"We've been able to overcome the first block," said study co-author Angela Christiano, a professor of dermatology and genetics & development at the Center for Human Genetics at Columbia University's College of Physicians & Surgeons in New York City.

Using seven donors, Christiano and her research team removed cells inside the base of human hair follicles and cloned the cells in tissue culture. A few days later, the researchers transplanted those cells to human skin that had been grafted onto the backs of mice.

As a result, the human skin on the mice grew new hair that lasted a minimum of six weeks in five out of the seven tests the research team performed. In addition, the new hair follicles genetically matched the human donors as confirmed by DNA analysis.

The research is currently in its early stages, and whether the technique will grow hair that's the same texture as it was previously remains unknown. What is known, however, is that an estimated 50 percent of people over the age of 50 suffer from hair loss, and there's a need for finding new ways to replace hair in those who need it that are better than any of the limited methods available today.

Such limited methods include drugs, which promote hair growth, but as Christiano warns, these drugs tend to focus on stimulating existing hair follicles to grow longer hairs, not necessarily replace lost hair. In male-pattern baldness, for example, men still have follicles that grow hair, but they just grow "peach fuzz" instead of normal hair.

Of course, other treatments for baldness and hair loss are available, including surgical procedures that graft hair into the scalp, but one expert says these options aren’t much better than drugs that promote hair growth.

I have used Rogaine for years. It didn't help for me bald hair growth. Then I tried another treatment, which my Doctor warned me could cause male issues. At that time I was single and didn't worry about it. I don't remember the name of the medication, but it didn't help either. Thus, after years of happy marriage I realized that growing hair is never a concern anymore. That's not who you are.
