No. Hairprint® does not work on blonde, red, chestnut or auburn hair because those hair types contain an additional pigment called pheomelanin. Hairprint® replaces eumelanin only. It is the pigment in all black and brown hair. However, we are continuing our development efforts to create products that will work on other shades. The "Dark" product will work on hair in the 1-2 range. The "Brown" product will work on hair in the 3-5 range. The "Light Brown" product will work on hair that is 6 on the color chart.
A blonde formula is in the works, so keep checking back!
