Place the arrowroot, or arrowroot and cocoa powder, into a small jar. Use 4 TBSP of arrowroot for light hair, and only 2 TBSP for dark hair.
Add the essential oil and mix to combine.
Apply with a make-up brush to the roots or oily parts of your hair. The brush is optional, but it removes the need to comb through as much and is better for styled hair. If you don’t use the brush, comb the powder through your hair and style as usual.
Notes
To make a spray that works as a dry shampoo, add 1 cup of warm, distilled water and ¼ cup of vodka, rubbing alcohol, or witch hazel to the above recipe. Spray on roots or oily parts of hair, let dry, and style as usual. Shake before each use.
