Mix ingredients together to form a paste. Add additional water, a few drops at a time, if the mixture is too thick. Shampoo hair as usual. Apply mixture to hair and leave on for up to five minutes. Rinse hair as usual. Poor Cider Vinegar Clarifying Rinse through hair, do not rinse again [the cider vinegar scent will very quickly dissipate]. If your hair is "squeaky clean" apply a light, silicone-free conditioner or silicone-free leave-in conditioner. This is best used for first-time clarifying, by those who use a full line of hair products that include silicone that have left behind a heavy build-up, or those who clarify rarely.
