Break the Matrix

Well, you know how it's 2:1 water to herb.  So let's say you steep 4oz of the nettles, rosemary and comfrey in water, you'll have 8oz of water.  You can pour 6oz of that into the shampoo and with the other 2oz you can keep it in a sealed jar in the fridge and apply it to your scalp after the shower.

You can apply coconut oil after the shower to the affected area as well but the honey/avocado would be gross to have sitting around in your hair all day, so I recommend it beforehand.
