Male pattern hair loss comes in several forms: thinning hair, a receding hairline, hair loss at the crown of the head, and loss in an "M" shape. Besides genetics, there are many factors that affect hair loss: diet, health, hair care routine, and hair tools.
There are a lot of treatments out there that promise much, but don't always deliver. It's important for consumers to speak directly with a medical doctor who specializes exclusively in hair loss before starting any treatments or undergoing a surgical procedure.
