If you feel like experimenting a little,
get a sheet of paper and some watercolours (red, blue, yellow). I am sure you
will understand the science of hair colour wheel better by doing so.
Here is the formula for hair dyeing:
Underlying natural pigments + artificial
pigments = result colour
By dyeing your hair you can enhance,
soften, neutralize and change the colour of both natural and dyed pigments.
Did you know that if you mix red, blue and
yellow you will get brown?
Brown is the base colour that can be
changed regardless of the deepness of the colour. (dark brown, brown, light
brown, dark blonde etc.)
