Natural oils: Oils like coconut, almond or olive can be used to keep the scalp moisturised and prevent dandruff. Simply warm up some oil in a bowl and apply with a scalp massage, ensuring that the entire scalp is covered. Wrap the hair and scalp in a towel and leave the oil on overnight. Then rinse the hair in the morning.
Vinegar: It can be used to keep your scalp from becoming flaky. After washing your hair, mix two cups of apple cider vinegar with two cups of cold water and use to rinse the shampoo from your hair. Alternatively, you could apply white vinegar to the scalp and leave it on overnight with a towel, and then wash out of the hair with regular shampoo the next day.
Baking soda: Replace your shampoo with baking soda for a few weeks; vigorously rub a handful of baking soda into the scalp and rinse thoroughly. Repeat as you would in your regular schedule of washing your hair.
