Stir in 10-15 drops of essential oil until thoroughly combined
If you want to add color to your bath salts, add one drop of food coloring and stir to combine. Continue adding one drop at a time (stirring after each drop) until you see the desired color. One or two drops should be enough. Adding too much food coloring can cause excessive moisture which may cause bath salts to clump or harden.
Pour bath salts into an air-tight container for storage
To use, simply add a few scoops to warm running bath water when filling the tub
