Overlapping dye onto previously colored hair is what creates dullness and dryness. If you color your hair @ home or salon, let your roots grow out as long as you can stand, so the line of demarcation is easier to spot. Only run color through the lengths for five minutes to refresh the ends. To extend the time between touch-ups, use a gloss and deep -conditioning treatments. They will help smooth cuticles roughed up by daily wear & tear, and the hair will look shinier. ~ Harry Josh, hairstylist of the celebrities.
Celebrity wears two-tone hair dye all the time, trying to grow out their dye. They call that the ombre style.

Chemicals can enter the body through the skin.

In 2009 the Mail revealed that women who used hair dyes more than nine times a year had a 60% greater risk of contracting blood cancer.
A year later the European Commission banned 36 hair dyes which put long-term users at risk of bladder cancer. < < <
