I suppose that many people don't know that you can't dye grey hair any color you want because there's no pigment in the hair anymore, and you can't bleach it. The primary colors you can do are platinum blonde, medium brown, and pure black. This happens because grey hair doesn't have oils anymore, and the chemicals in your dye can't go into the structure of hair and change the color. I suffered from alopecia several years in a row, although ii loved dying my hair and styling it. Thank god I decided to apply to the Experienced & Licensed Hair Transplant Team to make my hair look great again, and now I dye my hair about once a week.
