How should I lighten my eyebrows? Posted on August 8, 2012 by Baday I’m coloring my hair mahogany brown (i have dark brown / black hair right now) but my eyebrows are black. . . like REALLY black. It looks nice with my dark brown / black hair but I think it’ll look too black with mahogany brown hair. I do not want to bleach it. . . It’s too scary. Yeah. No expensive ways too.
