To transform black hair into silver grey hair, the hair needs to be lightened to a very pale blonde shade before applying the silver grey color. This can be achieved through a process called bleaching, which removes the natural pigment from the hair. Once the hair is lightened to the desired shade, a silver grey hair dye can be applied to achieve the desired color. It's important to note that this process can be damaging to the hair, so it's best to seek the help of a professional hairstylist to ensure the best results and minimize damage. **
