Is there red tones in ash hair colors?

No, not in the dye itself. But here is the crazy thing: your hair could still LOOK reddish in the sunlight! Ever wonder HOW in the world that could be? Let me explain. The actual hair shaft has pigment in it. If your hair is brown, for example, and you want to color it, the mix you put on your hair has a developer in it. The job of a developer is to "lift" the smooth shaft and make it porous, and get rid of some of the pigment. So under all that hair colorant goo on your head, chemically your hair goes from brown, to red, or even orange or gold depending on the level of developer/ timing etc. (think of any bleach job gone wrong and you can imagine it). Of course your hair doesn't STAY this raw color, because you ALSO put dye in the mix. The dye color gets deposited, and that is the ash color you ultimately see when it's dry. Fast forward some days after the color begins to fade and you may see red, or gold. What you are beginning to see can be the remains of the brown hair shaft after it has been exposed to the peroxide of the developer. Essentially, your hair got bleached so it would accept the new color. Your hair is STILL somewhat bleached after the color begins to fade. On some people, that looks red!
