“Balding Is Now Optional.”

The Atlantic – In the tunnels under New York, commuters squeeze into lumbering trains and try not to make eye contact with the people whose sweaty bodies are pressed against theirs.

As they surrender to the will of the transit authority, their eyes wander upward to find an unlikely promise of control: Many cars are plastered with ads that say “Balding is now optional.”

Despite a rare confluence of commercial forces and scientific interest, generating new hair remains outside the realm of the possible.

This could be changing, though—and not owing to new packaging of the same old medicines.

Recently a series of scientific publications has explored advances that involve both stem-cell research and 3-D printing, with the goal of cloning a person’s actual hair and then inserting it into his or her scalp—in tremendous, unlimited quantities.

“For a long time, we’ve been saying this is 10 years away,” says Robert Bernstein, a dermatologist in Manhattan who specializes in hair transplantation. “But now it actually might be less.”

Of all the parts of the body to create in a lab, hair could seem like the simplest … Read more.
