Although not as common as regular shampoo, waterless shampoo can be found on the shelves of most grocery stores. Dry and other waterless shampoo are helpful when caring for people who are ill, in disaster situations when access to running is scarce, and while hiking or camping. Dry and waterless shampoos are used differently than regular shampoos. Both types require brushing out impurities and oils.
Powder-Based Dry Shampoos
To create a dry shampoo using cornstarch, mix 1 tbsp. salt and 1/2 cup cornstarch. If you want, grind the salt before adding it to the cornstarch so the granules are the same size for both items. You can also use cornmeal instead of cornstarch. Baby powder works in the same way. There is no need to add salt if you are using baby powder. Sprinkle the powder into the hair and brush out impurities.
Egg White Waterless Shampoo
It you don't want to deal with the mess of powdered shampoo, use egg whites, which are a little easier to contain, as a waterless shampoo. Separate an egg. With either a whisk or an egg beater, beat the egg white until it forms a stiff peak, as in, when you touch the egg white, the peak that forms when you withdraw you finger doesn't move or fall. Put a towel over your shoulders and massage the whipped white in your hair. Allow it to dry. Brush out the dried white.
Application and Storage of Powdered Shampoo
Powder-based shampoos can be stored for a long time, unlike whipped egg whites. Store a powder-based mixture in a container or bag. To aid in application and storage, use a container with a lid. Stretch plastic wrap over the opening and use a rubber band to hold it tight. Puncture the plastic wrap to make a dry shampoo shaker. Cover the container with the lid, leaving on the plastic wrap, for storage.
