Set up a double boiler on the stove, this is a pot filled 1/3 of the way up with boiling water and a heat-safe bowl placed on top.
Once the double boiler is hot, add your shea butter and coconut oil into the heat-safe bowl. Stir continuously until both have melted completely.
When the shea butter and coconut oil are melted, turn off the heat.
Add the arrowroot powder and essential oils, and stir until combined.
Working quickly, pour the hot mixture into your lotion container, I like using mason jars since they are heat-safe.
Allow the DIY mosquito repellent lotion to set completely on the counter, this will take a few hours if it is hot inside your house. You can also put it in the fridge to set up quickly.
Once completely set, take a small dime-size amount of lotion and apply it to your body. A little goes a long way!
