Place soap nuts in the small muslin bag. Or wrap the soap nuts in cheesecloth and tie together with a piece of kitchen twine.
Place the soap nuts in a medium saucepan with water and bring to a boil. Cover, reduce heat to low and let simmer for 30 minutes.
Remove from heat and, without removing the soap nuts, let cool completely.
Squeeze out the bag until you see suds. Rinse the bag with cold water and squeeze in to the pan again.
Add apple cider vinegar and essential oils. Stir to combine.
This does make for a very runny, watery shampoo, which is why I also suggest using a glass spray bottle instead.
To use, spray your hair and scalp and gently massage in. Let sit for five minutes, then rinse out and condition.
