Put the coconut oil into a cup, bowl, or glass jar. Place the jar into the microwave until the coconut oil is fully melted.
Take the jar out of the microwave. Add the essential oils (if used) and stir to mix.
Add the Himalayan salt into a medium bowl. Pour the coconut oil mixture over the salt and mix using a spoon. Use your hands to mix the oil and salt together. The heat from your hands will slightly melt the coconut oil enough to incorporate the two ingredients together.
Transfer your DIY Himalayan salt scrub into a storage container.
