Apple cider vinegar helps balance the pH level of your scalp. To use this method, mix 2 tablespoons of apple cider vinegar in one cup of water. After washing your hair, pour the apple cider vinegar and water mix over your hair, and rinse out after 3-5 minutes.  Rinse with cold water. You can do this up to 3 times a week. Squeeze the juice from two lemons, and mix with two cups of water. Massage the lemon and water mixture on your hair for 3-5 minutes, then rinse your hair with warm water. Repeat 3 times a week. Keep in mind that this could cause your hair to become lighter. Mix 1 teaspoon of aloe vera gel, one tablespoon of lemon juice, and one cup of your shampoo. Wash your hair with the mixture, allowing the shampoo to sit for 3 minutes. Then, rinse with warm water.  Repeat this method up to a few times a week. If you don’t use the whole shampoo mixture, store it in the fridge for up to a week. Mix one part baking soda in three parts water to make a paste for your hair. Longer hair will require more paste. Rub the paste into damp hair and leave it on for 5 minutes. Then, wash your hair with warm water. Repeat this method twice a week.
