Add coconut oil and shea butter to a small mason jar. Bring a small pot of water to a boil (filled 1/4 of the way), and place mason jar inside the pot, effectively creating a double-boiler method.
Continue warming until the coconut oil and shea butter have melted. Remove from heat, and add argan oil and peppermint essential oil to the mixture, and give it a good stir.
Whip mixture for several minutes, until starting to get fluffy and buttery.
Add mixture directly to scalp, roots and throughout the hair. Top with a shower cap and allow to sit for 30 minutes. Rinse, shampoo and condition as normal.
