Hair Replacement: The Next Generation
Coming soon to a scalp near you?
The Evolution Continues
"Hair transplantations have continued to evolve into
smaller and smaller grafts and the next step will be to add a cell-based
transplant where you can inject hair seeds into the balding area that can grow
into a brand new follicle," predicts Ken Washenik, MD, PhD, the medical
director of Bosley, a hair restoration practice.
In essence, this is cloning.
"Within five years, we should be able to augment and add
this to the follicle-based transplant," says Washenik, who is also a
researcher at the New York University School of Medicine in New York City.
"Cloning has certainly become possible in other areas, so
it is very possible that there will come a time when hair can be cloned,"
"If we can get cloning to work that would give us the best
ability to restore hair," says New York City dermatologist Bruce Katz, MD,
director of the Juva Skin and Laser Center. He says it would deliver the best
results, physically and cosmetically.
The Magic Bullet?
A magic elixir to treat baldness "may not be that far off
if we extrapolate from existing drugs like Propecia and keep going,"
Orentreich says. "I am pretty confident that with further work, a
medication will come along that will be so good and safe that we will be doing
Finasteride (Propecia) was developed to treat an enlarged
prostate and later was found to be effective in hair loss in men. It is
prescribed under the names Propecia or Proscar.
"It's OK, but not so good that all men who take the drug
will grow their hair back, but it's excellent if you start to use it when you
first notice thinning hair," Orentreich says.
Propecia works by lowering the level of a hormone called DHT
(dihydrotestosterone) in the hair follicle, a male hormone linked to hair loss.
Like Propecia, another drug Avodart, was also designed to treat enlargement of
the prostate by blocking DHT and may help treat hair loss.
"Sooner or later, there will be a fabulous drug which
blocks DHT that will be able to prevent hair loss and we will see a much
greater number of men grow their hair back," Orentreich predicts.
May the Force Be With You?
Light or laser therapy may also play a role in hair restoration
of the future, says David Michaels, managing director and developer of HairMax
Lasercomb, a comb that emits light energy to help stimulate hair to grow.
Michaels is currently in the process of submitting further data to the FDA for
approval and hopes to get clearance within a year.
In clinical studies, people who used the comb three times per
week for five to 10 minutes per time saw hair growth on average of 93% within
"A laser or light source can stimulate follicle to grow
again and produce healthy hair," says Katz, who has no affiliation with the
