A good shampoo for black is essential for maintaining its beauty. There are several options to choose from. The best one is the oil-based kind as it seals in moisture and leaves hair moisturized longer. You can choose the one that contains natural oils such as jojoba, avocado, grape seed, olive oil, coconut oil, and emu. Avoid mineral-based shampoos as these will cause buildup on that and make it dry. Lastly, choose a shampoo with large quantities of detergent.
