You've heard it all before. You get it from your mother's father. Wearing your favorite baseball cap is making it happen. Oh, and not to add to your stress, but work is contributing to it as well.

With all the information (and misinformation) surrounding hair loss, it's hard to get to the facts. Well, worry not. Here we give you the real truth behind the most prevalent baldness rumors.

Rumor 1: Smoking can contribute to baldness.

True. According to a study published in the Archives of Dematology, researchers at the Far Eastern Memorial Hospital in Taipei gathered information about the age at which the men started losing their hair, and risk factors which may have affected their hair loss.

Smoking at least 20 cigarettes a day was linked to an increased risk of baldness, even after other risk factors were taken into account.

Rumor 2: Wearing a baseball cap will cause baldness.

False. Although wearing a tight fitting cap or can cause sweating and interfere with blood circulation to the hair follicles, there is no scientific proof that they are capable of causing hair loss in men. In fact, hats are much more likely to cause severe headaches than hair loss.

Rumor 3: Losing 100 hairs a day is NOT normal.

False. Actually, that's very normal. According to the American Academy of Dematology, the average person sheds approximately 50 to 100 hairs daily.

Rumor 4: Brushing your hair too often will cause hair loss.

False. While excessive hair brushing can lead to breakage and split ends, it will not cause you to go bald.

Rumor 5: The "baldness gene" comes from your mother's side of the family.

Partly true. More than 95 percent of male hair loss is due to male-pattern baldness, a genetic trait. However, the gene can come from either parent.

Rumor 6: Stress can cause hair loss.

Partly true. According to the Mayo Clinic, telogen effluvium, the most common form of hair loss, is triggered by extreme physical or emotional stress. The condition forces hair follicles into a resting phase which, over time, causes the affected hairs to fall out. While the initial affects may be traumatic, the hair generally grows back over time.
