Suggested use of a mixture of apple cider vinegar and water.
Mix 2 cups of warm water with 1/2 cup of apple cider vinegar and pour it over your hair after you shampoo and rinse.
Avoid your eyes and any open sores.
Because the solution is diluted, this vinegar rinse won't smell quite as strongly.
Leave it on your scalp for about 3 minutes then rinse off and follow with conditioner if needed.
