Full beards and mustaches are big business in Istanbul, where clinics are busy booking new and returning clients from across the Middle East who want to enhance their facial hair.

Having these features is more than just a longtime trend; it's also a source of power and pride — and not having enough facial hair can be a problem, according to Dr. Melike Külahçı, who does implants to remedy that.

"It looks like being sick. It looks like not being able to treat yourself or care for yourself. It doesn't look good," she said in a CBC Radio documentary.

Reporter Steve Dorsey took to the streets of Istanbul to investigate the hair enhancement scene and filed this story for The World This Weekend.
