Add the coconut oil, shea butter, and beeswax pellets to a double boiler.

Heat gently until everything is fully melted, stirring occasionally.

Remove from heat and allow the mixture to cool slightly (it should be warm, not hot).

Stir in the castor oil and sweet almond oil until fully combined.

If using essential oils, add them now and mix well.

Pour the mixture into a clean jar or tin.

Let it cool and harden completely at room temperature.
