Mix both ingredients in a bowl using a wire whisk to fully incorporate.
Pour mixture into ice cube trays. (I used two full trays.)
Put in freezer and wait a few hours until frozen completely. At this point you can transfer them to some sort of bag or container, or just keep them in the trays.
To use: Take one cube out before you want to use it (at least the night before) and keep it in a small container or bowl in the fridge until you are ready to shower. Use as you would normal shampoo (about a quarter size amount).
Work into the scalp and then move toward the ends of your hair. Let sit for 30 seconds or so and then rinse completely. This will not lather... so don't keep adding more thinking it will get your hair 'more clean.' Like all good things in life, a little goes a long way. I would also HIGHLY recommend using an apple cider vinegar rinse, especially if you experience that 'waxy' feeling after using this.
Place any remaining mixture back in the fridge to use next time you wash your hair. The shelf life of each cube is about 1 week in the fridge. Just be sure to take a new cube out when you use up the other one.
