To truly turn white hair black, several methods can be considered. Firstly, maintain a healthy lifestyle. Eat a balanced diet rich in vitamins and minerals, especially those beneficial for hair health like iron, zinc, and biotin. Get enough sleep and manage stress effectively. Secondly, use natural remedies. For example, massaging the scalp with oils like coconut oil or amla oil may help nourish the hair follicles. Henna can also be used to give a natural color to the hair. In some cases, medical treatments such as taking supplements or undergoing laser therapy might be recommended by a doctor. However, results may vary from person to person, and it's important to be patient and consistent with the chosen treatment method.
