Abstract
Oxidative hair dyeing systems are provided that are 'root seeking', i.e., which produce more intense initial coloration on new growth, less porous hair compared to the initial coloration produced in older, damaged, more porous hair. More equalized coloration along the shaft of hair can be obtained with the 'root seeking' dyeing products.
