Myth: If you want to hang onto your hair, stay away from gel and hairspray.
No need to forgo the products—they don't cause balding, and neither does shampoo, washing your hair frequently, or dandruff. But some men tease their hair and use curling irons, which could speed up the process. "It's the over-mechanical utilization of hair that can be problematic," Sadick says.
Myth: Exposure to the sun encourages balding.
Not true. Tanning beds also don't have an effect.
Myth: Loading up on carbohydrates can lead to hair loss.
Carbohydrates and red meat provide nutrients that are helpful for maintaining a full head of hair, says Wilma Bergfeld, a dermatologist at the Cleveland Clinic. Bergfeld's past research suggests that iron deficiency may be closely linked to hair loss. Treatment—like taking iron supplements—could restore growth.
Myth: The most sexually active men are the first to go bald.
This is one of the most popular myths Sadick hears from patients. Relax, he says—there's no truth to it. Research has also found that men who bald do not have more testosterone than their hairier friends.
