Greasy hair looks and feels unattractive, and excess oil can ruin even the most flattering of hairstyles. While a thorough cleaning with shampoo will remove the greasy residue from your hair, sometimes you just don't have time to wash your hair. Dry shampoos are designed to absorb the grease and allow you to brush it right out of your hair. Baking soda will do the same thing and you probably already have some on hand in your pantry.
Sprinkle up to one tablespoon of baking soda onto the roots of your hair. Try to get the baking soda as close to the scalp as possible so that it can absorb the grease on your scalp.
Run your fingers through your hair gently to evenly distribute the baking soda. Do not attempt to remove the baking soda from your hair; just spread it around.
Allow the baking soda to sit on your hair for approximately five minutes. This will give it time to absorb the oil in your hair.
Comb through your hair to completely remove all of the baking soda. Brush your hair with a natural bristle hairbrush until no trace of the powder remains if you are having a difficult time removing the baking soda with a comb.
You can also use corn starch in the same manner if you don't have any baking soda.
