Re-coloring and highlighting

Hello!  My naturally dark brown hair is professionally colored a medium neutral brown with golden highlights.  I would like to darken (deepen) the color to a richer brown shade and have it re-highlighted with chunky caramel highlights. T

Would this be damaging to my hair?

Thanks!

 

 

And the rule of thumb is that the more deposit, less lift (i.e. going from a
lighter to a darker shade) the less damage. It is lifting the color -
bleaching for the most part - that does the real damage. Take good care
of your hair and you should be fine! Just make sure to buy a color
protectant shampoo and conditioner like John Frieda Brilliant Brunette so
you won't end up dying your whole head every time you just want to
touch-up your roots.
