Research shows that by age 50, 85 percent of men have thinning hair. Let’s examine some popular myths around hair loss.

All hair loss is permanent.

Not all hair loss is forever. People with alopecia areata, or spot baldness, may experience patchy hair loss, but hair can regrow.

Stress makes your hair fall out.

There is a connection between stress and telogen effluvium, a temporary form of hair loss following a traumatic event, and alopecia areata. But stress does not cause male pattern baldness.

Extra testosterone can make you bald faster.

Nope. You and your friend with a full head of hair most likely have similar levels of testosterone.

Wearing a hat speeds up hair loss.

Wrong. However, dirty caps can cause a scalp infection, which could speed up hair loss.

Sun exposure makes hair thinning worse.

Too much sun can cause some shedding, but UV exposure doesn’t stop hair from growing.
