Coloring hair works a lot like using markers on construction or colored paper. You can't use white or yellow markers on black paper, can you? They don't show up, do they? You need lighter paper for lighter colors to show up, right? The same applies for hair color.
If you want any color lighter than your natural color, you MUST bleach it. There is no way around this. How you bleach and how you treat your hair before, during and after the process can greatly affect the damage done. If you don't know how to do this, shell out the money for a professional salon. And I mean a SALON, not Hair Masters or Great Clips or any s**t place like that, a legit SALON, with people who know what they're doing.
Also, to do a dip-dye like you're wanting to do, tying your hair into a ponytail is not the way to do it. You need to paint small individual sections of your hair with the color for it to look right, even, and fully colored. There are several Youtube videos to show you how to do this, some also call it ombre. So you can look up "ombre" and "dip dye" and get the same results.
Does that mean I have let the salon dip dye my hair as well?
If you're going to have a salon bleach your hair, you might as well let them color it for you, too. Again, the Youtube videos will at least show you the procedure, but having someone actually do it for you and walk you through the process as it's happening is better.
Dipping your ponytailed hair into a jar of color like a paintbrush isn't how the dip-dye or ombre process is done. That will give you uneven color, splotchy color, and it will look terrible, I can pretty much guarantee it. You separate the hair into small sections, paint the color in to as high as you want it, then wrap it in plastic or foil, and move on to the next piece. You don't want a straight line across where the color stops and the rest of the hair begins, that will look terrible. You want it slightly messy, slightly uneven, it looks more "natural" that way.
