Wash hair w baking soda and vinegar. My hair has grown a ridiculous amount and is now the longest it's ever been. It also takes 4 days for it to even get SLIGHTLY greasy, where as before it would start getting greasy in less than 18 hours. I will NEVER go back to regular shampoo.
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.
