Dr Oz: Extreme Myths Exposed with Science Bob
Dr Oz did a show with Science Bob called Extreme Myths Exposed. They tackles some of the biggest Ant-Aging Myths. Does stress turn your hair gray? Are Teeth Whiteners the best way to whiten your teeth? Does lack of sleep cause bags under your eyes? And what is the secret reason that you have wrinkles (click here to find out: Dr Oz: Wrinkle Causes)? Doctor Oz has done excellent shows with Science Bob in the past, so definitely take a look at these recaps of past shows too: Dr Oz: Mom Myths Exposed and Dr Oz: Does Hydrogen Peroxide Disinfect Cuts?
Dr Oz: Does Stress Turn Hair Gray?
Dr Oz’s first myth to tackle was whether or not stress turns your hair gray. There seems to be compelling evidence for this claim, since Obama and just about every other president to get into office gets more and more gray hair while they serve. But as it turns out, there is no scientific proof yet that can tie stress to gray hair. Science Bob said that the cause of Gray Hair is actually a chemistry battle between Hydrogen Peroxide which is found naturally in your hair and another enzyme that keeps your hair from turning gray. Dr Oz showed an image of a hair follicle and at the base is a cell that squeeze pigment into the hair to give it a color. If this cell gets damaged, then the pigment stops being injected. Science Bob believes that if we can understand how Hydrogen Peroxide influences our hair exactly, we could cure the problem of gray hair forever!
Science Bob and Dr Oz did an experiment to demonstrate the difference between young hair and older hair that turns gray. Please remember not to try any of these experiments at home! Science Bob had one container full of Hydrogen Peroxide, and another container that represented the chemical that influences the color of your hair. In the young hair, the foam that was produced was a dark color. However, in the second container that represented older hair, the natural enzyme that was added to the Hydrogen Peroxide produced a white, fluffy, souffle-like substance to represent gray hair.
So the bottom line is that stress does not seem to turn your hair gray, it is the buildup of Hydrogen Peroxide that causes your hair to bleach.
Dr Oz: Teeth Whiteners Are Dangerous or Safe?
Doctor Oz’s second myth to explore was whether or not Teeth Whiteners are the best way to whiten your teeth. We spend $1.5 billion every year on over-the-counter Teeth Whiteners that claim to give us sparkling white teeth, but do they really work to transform yellow teeth to white? And are they even safe?
Science Bob filled white balloons with a little water to represent young teeth which have all of their enamel. A flame represents the damage that a Teeth Whitener can cause, but when he held the flame to the water-filled balloon, nothing happened. This represents what happens in young and healthy teeth, which is that your enamel protects your teeth from the whitening agents so that there is no damage as long as you use the products correctly. Older teeth were represented by yellow balloons filled with Hydrogen, and when you hold a fire to them, they explode. The same thing happens with Tooth Whiteners, which can be very dangerous (and highly ineffective) for people who no longer have their enamels.
Dr Oz said that you can often tell if your enamel has worn away or not by if your teeth are sensitive to cold foods. If cold food hurts your teeth, then definitely check with your dentist before using any Teeth Whiteners. And if you are ever in doubt, it is always safest to check first with your dentist either way! If your enamel is intact and you want to try something more natural, you can try Dr Oz’s Teeth Whitening Remedy that he spoke about in another segment too!

Dr Oz: Under-Eye Bags Caused By Lack of Sleep?
Dr Oz’s third myth was whether or not lack of sleep causes bags under your eyes. Around 3/4 of us do not get enough sleep, but is this what is causing our puffy under-eye bags? Doctor Oz said that he hates his under-eye bags but they are usually caused by fat that slips out under the eye. We have fat deposits all over our body, but if your skin is strong enough, then it can hold the fat in place. Science Bob did a demonstration to show how our skin is firm, bouncy and resilient when we are younger (25 and under). However, as you age, the skin under your eyes gets thin and the ligaments get loose so that fat can start to protrude out and cause under-eye bags. So this is another myth that is busted! Lack of sleep does not cause Under-Eye Bags, it is a natural process that happens in our body as we age.
