My eyebrows are really thin, and they are too lighter shade of brown than the color of my hair. Lately, I am feeling that I should go for permanent eyebrows, there are a few guys who found it quite good experience, while there are others for whom it did not work. I would like to know from some skin expert whether constant coloring eyebrows would gradually cause me to have no eyebrows! I am really perturbed, as I am using chemical dye to color my eyebrows, and it becomes an ordeal for me! Can you guys please advice?
