Scientists say they have stimulated the
growth of new hair in mice, disproving a long-held belief that it is
not possible to correct baldness in adults.

Experts say
that people suffer hair loss, because the follicles shrink and
eventually disappear with age. But they discovered they can stimulate
the growth of new hair-producing follicles in mice by damaging their
skin.

George Cotsarelis, an investigative dermatologist at the University of Pennsylvania School of Medicine
says researchers used an abrasive technique similar to one used on
humans to remove facial acne scars, except that they used the technique
on the skin of laboratory mice.

In the
study, the abrasion caused wounds and the healing of the wounds
triggered an embryonic state in the rodents’ skin, which became
receptive to instructions from a protein called WNT.

The scientists discovered they could control the amount of hair growth
either by blocking the amount of WNT proteins, stopping follicle
formation, or over-stimulating WNT and doubling the production of
hair-producing follicles.

“That suggests that wounding creates
this period of time where you can manipulate the regeneration of the
follicles,” he added. “So, you can actually increase the number
that’s formed.”

Cotsarelis
says the new hair in mice was white, because the animals have no
pigment throughout their skin and humans have pigment throughout their
skin so new hair would likely be colored.

Cotsarelis
is exploring
these discoveries for a company he helped found to examine hair
regeneration in humans and to find hair loss treatment methods.Best
results in achieving the perfect treatment for baldness has the
