So, I apologize for this potentially stupid question, but I've never dealt with this before, and I thought this might be a good place to ask.
One of the downside to red hair is that the color can fade depending on a variety of situations. I think having my hair longer + natural change over time + California air/sun (at least, I blame California!) have my hair currently looking a bit weaker in the red department than I'd like. (In some light, I look like more of a light brunette.)
I've never given the idea consideration before, but how do hair coloring products work if you're just looking to enhance your natural color? I've dyed my hair drastic colors a few times just for fun, and I don't want to do anything along the lines of going fake red. Are there things that you can buy that are based around just making your natural color a little bolder/whatever, or am I crazy in thinking that such things exist?
