Why did my blond hair turn gray when coloring to medium blond?
the best i can tell from listening to your story is that your hair has not been offered rest and excessive coloring and overcoloring from light to medium blond shades has made them resist any further color intake and finished the absorbment level from it .my suggesstion to you would be to give good rest to your hair from coloring and trim them .the newer the hair grow the better they would adapt to coloring.
