Red hair color charts, or color swatches, are usually included as a resource on or near boxes of hair color in hair specialty stores. Otherwise, helpful color charts are readily available online. It is always advisable to visit your favorite hair color brand's website for details about specific red shades.
Many brands of professional hair dye include a wide variety of red shades in their lines of hair products. However, just because the color looks great on the model on the box doesn't mean it looks great on everyone.
Some red hair color charts are organized not only by hair color but by skin tone, which gives you a better idea of what color looks the best on you. While there are plenty of generic color charts online, the best thing to do if you are uncertain is talk to a salon professional so that you choose the correct shade. However, keep in mind that an 8R in one brand may look entirely different from an 8R in a different brand. Also, your current hair color affects which red shade you ultimately choose, and many at-home hair colors warn that red hair turns out brighter on hair that has 50 percent or more gray.
