How do you make dyed black hair look natural?

You can't. Black hair dyed never looks natural. But you can shade it several shades darker to a very dark brown and make it look darker. The way to do this involves several dying sessions. hover you should consider keeping your hair color as it is considered fashionable among south Americans to have the lighter tousled look for a woman of Hispanic background. Technically you inherited both your dad's and your mom's hair color as the lighter color is recessive which meant both parents needed to carry it.
