Fill the bottom of your double boiler with water and bring to a gentle simmer. Add the beeswax to the top portion and allow it to melt slowly over low heat.
Once melted, add the tallow and stir until fully liquified.
Add the castor oil and jojoba oil. Stir gently until combined. Then, remove from heat and allow the mixture to cool for about one minute. Add essential oils if using and stir again.
Pour the mixture into your container and allow it to set completely at room temperature. The pomade will firm as it cools.
