Dry shampoo can be easily made at home using nothing more than 1/4 cup of arrowroot or cornstarch and an old make up brush, with five optional drops of essential oils. Dry shampoos are made to absorb hair oils so that even when unwashed, one's hair will still look clean. While store-bought dry shampoos can be expensive and contain aerosols and unwanted chemicals, homemade dry shampoos can be made to have the same effect.
To make dry shampoo, one must thoroughly mix the drops of essential oils with the arrowroot or cornstarch. This will serve as the oil-absorbing mixture. After creating the concoction, one should spread the mixture onto the hair with a make up brush. The brush will help spread the mixture throughout the hair to create a clean all-around look. While this mixture might not work for dark hair due to the light color, 2 tablespoons of cocoa powder can be added to give it a dark natural color.
If one is looking to make wet-dry shampoo that is easy to spray onto the hair, then he or she can create the same mixture but with the addition of 1 cup of warm water and 1/4 cup of vodka or rubbing alcohol. Perfume can be added to the mixture as well to give the hair the scent that one likes.
