NEW ZEALAND — Here’s a story that might make you muscle heads out there drop your weights. Doctors now think weightlifting and protein powder drinks play a key role in balding.

They believe it’s all because body building can increase the body’s testosterone and DHT levels which can cause hair follicles to shrink and die.

But one local trainer isn’t buying it!

“I think what’s happening actually is the male pattern baldness is a result of testosterone replacement therapy and them basically taking steroids,” said Rob Lord, Founder of The Alpha Project. “It has nothing to do with just weight training and taking protein shakes, that seems completely ludicrous.”

Lord advises people to do their own research when they hear reports linking weight lifting to hair loss.

“Really ask yourself, who’s paying for the study, how many participants are in it? Because almost all the time these studies are funded by big corporations that definitely have an agenda,” he told NewsFix.

So if you lift weights, you decide — this theory may all be a bald-faced lie.
