Some home remedies to remove build up from hair include washing the hair in apple-cider vinegar or baking soda. According to InStyle Magazine, hair stylists suggest washing the hair with dish soap, specifically Palmolive. Because the detergent is so strong, it is also recommended that the hair be conditioned with a hydrating deep conditioner after using dish soap.
To remove build up in the hair using apple-cider vinegar, mix 3/4 cup with 2 cups of warm water, and scrub the mixture over the hair and scalp in place of shampoo. Then, rinse the hair with cool water to close the hair cuticles. The apple-cider vinegar leaves the hair shiny and clean. The smell of the apple-cider vinegar goes away as soon as the hair is dried.
To wash the hair with baking soda, mix 2 cups of warm water with 1/2 cup of baking soda until it is completely dissolved. The paste reaches a smooth consistency by the time it is mixed together well. After using the paste to scrub the hair, rinse the hair well in warm water, and complete the process by rinsing the hair with cool water. The last step closes the cuticles. Another alternative is to mix approximately 2 tablespoons of baking soda directly into shampoo, and wash the hair as normal.
