I've done this since a child ...Put a tiny bit of toothpaste into a small cup, mix in one teaspoon baking soda plus one teaspoon of hydrogen peroxide, and half a teaspoon water. Thoroughly mix then brush your teeth for two minutes. Remember to do it once a week until you have reached the results you want. Once your teeth are good and white, limit yourself to using the whitening treatment once every month or two.
My great grandmother said that her mother used to do this. When she died she didnt have a gray hair. Teabagging your hair! Blondes: Chamomile; Red: Rooibos; Brunette: Black. Once a week, steep 2 tea bags in 2 cups boiling water for 10 minutes. Let the liquid cool to room temperature. Pour the mixture over wet, just-washed hair, rubbing it through the way you would shampoo. Leave the rinse on for 10 minutes; wash and condition to seal in the silky, glossy results.
