After gardening or other chores that get your hands dirty, add 1 teaspoon sugar to your soapy lather, and wash your hands with it. The sugar acts as an abrasive to clean away stains.

Twice a month, rinse your hair with antiseptic mouthwash to help prevent mild cases of dandruff.
Do not use this remedy if you have cuts or abrasions on your scalp—it may be irritating.

If your nail polish has gotten thick and gloppy, let the bottle sit in hot water for about 5 minutes, and it should be as good as new.

In a small bowl, thoroughly whisk together ⅛ cup of your favorite shampoo along with 1 teaspoon of avocado oil (available at health food stores) and ½ tablespoon coconut milk (available at supermarkets). Shampoo as usual, then rinse. This doctored-up shampoo should nourish your hair and leave it with a wonderful shine.
If you have very long hair, double the amounts in the avocado-coconut-shampoo formula.
