TRUTH: "Hats off to this myth," Leonard said. No matter what you may have heard - wearing a hat does not cause hair to thin or fall out.
TRUTH: "Chlorinated water can affect the hair shafts by drying them out and making them more brittle, but does not cause hair to thin or fall out," Leonard said. But he does warn people to watch out for bleached hair because it has been known to turn green with exposure to chlorine!
TRUTH: Any saltwater activity, including swimming, will not cause hair loss, Leonard said. The real problem is genetics, which is the root cause of 98 percent of hair loss.
TRUTH: It's important to use sunscreen on your scalp, especially if you have thinning hair, to prevent a sunburn.
"In fact, one of the first hints that a person is losing his or her hair is, indeed, sunburn," Leonard said.
TRUTH: Again, the main concern with overexposure to the sun is getting a severe sunburn on your scalp - not hair loss.
And if your hair is thin enough that you risk getting a sunburn on your scalp, Leonard has some suggestions.
"Growing more hair, either with medical treatments or with modern hair transplantation, are great options to consider if your hair is thin enough to get burned," he pointed out.
TRUTH: "I don't know where this common belief comes from, but it just isn't so," Leonard said.
However, if your hair is thinning, there are some tricks of the trade that can help out.
"When one's hair is thin, seeing a hair care professional for styling tips such as foiling and layering will create the illusion of a thicker, fuller head of hair," he said.
TRUTH: "Very commonly, people believe that washing their hair causes it to fall out," Leonard said. "Sure, you see hairs in the shower drain because the mechanical action of shampooing loosens hairs, but it does not cause thinning. The hair shafts are already loose in the follicles because of male and female pattern hair loss."
The bottom-line: Daily shampooing is the best for the health of your follicles, according to Leonard.
TRUTH: It's genetics, not stress, that causes the vast majority of hair loss in our society.
"Just think, with the stress levels we all are living under these days, everybody would be bald! If you are truly having thinning hair or baldness, it is important to seek out a board certified hair restoration surgeon to be properly diagnosed and to be educated on what medically or surgically can be done for your hair loss problem," he concluded.
