Can you directly dye black hair?

In the realm of hair care and cosmetics, many seek to transform their natural hair color to suit their personal style or preference. The question then arises: can one directly dye black hair to a different hue? The challenge lies in the fact that black hair pigment is particularly dense and resistant to change. Standard hair dyes often struggle to penetrate this dense color barrier, resulting in a less than satisfactory outcome. So, the question begs to be asked: is it truly possible to directly dye black hair to a lighter or contrasting shade, or does the process require more nuanced steps and considerations?
