Q&A for How to Make Hair Color Last Longer

Only use conditioner when you're washing your hair to keep your hair hydrated and healthy.

Vinegar can lighten hair color slightly, especially with repeated use. It may also add warm highlights.

Natural warm colors last the longest. Cool and vibrant colors fade fastest.

This depends on the color of the dye and how healthy your hair is. Usually, every other hair appointment, or about every 12 weeks, the color will need to be refreshed.

You can't completely prevent hair color from fading. However, washing as little as possible and using products designed for color-treated hair will help.

It's okay to have the dye set in a little longer then the box says. There are a few things you can do that might help the color stay in longer. The one I know from experience is to use a really good brand of dye like L'oreal. Or, if you're bleaching your hair, keep it blonde for a day before you add in the color to give it time to settle in.

Have you tried mixing the same color dye with the same amount of conditioner? It works for me.
