Collection: Hair Color

Two leaf powders that color hair, one ingredient each: Henna, Lawsonia inermis, and Indigo, Indigofera tinctoria. You mix them yourself with warm water. Henna on its own gives copper to red; henna and indigo mixed in one step give brown; henna followed by indigo gives black. Neither can lighten hair, and both are for hair only. To cover gray without synthetic dye, covering gray hair with henna and indigo compares the three routes, and is there a "chemical-free" hair dye? explains what plant color is and isn't. Indigo can't be quickly washed out: indigo not working? explains what to do. Patch test 24–48 hours before first use, and strand test a hidden lock.
