well, what I do is scoop about 1/2 cup of baking soda into a jug. The jug can hold about 4 cups of water. Then I fill up the jug, in the shower, with about 4 cups of warm water, mixing the baking soda by hand as it fills up. I pour that over my head and let it do it's job while I wash the rest of my body. After I rinse the rest of myself off, I let the water rinse my hair out. I don't run my fingers or anything through my hair, I let the warm water do the trick. Then I pour some ACV into the bottom of the jug. I don't have a specific measurement for that; about 1/2 cup I guess is what I usually have. I fill up the jug again with warm water to the top (4 cups) and pour that mixture over my head. I let it sit for a while, then I rinse it out with cold water, again just letting the water do the rinsing.
I do not have the essential oils yet. I ordered them and they will hopefully come this week. I bought tea tree oil and rosemary oil
