If you want a new hair color, cover gray hair, or just quick root touch up, first read on some helpful tips first to avoid any color disasters.
Luckily, there are increasingly sophisticated, fail-safe products on the market, but don't expect to get dramatic dimensional effects or precise, salon design.
If you're satisfied with something on the simple side, here's how to get the perfect haircolor.

How to Get Hair highlights at Home
You can easily achieve gorgeous at-home hair color – but you have to pick the right shade for you in the correct color category to avoid horrible highlights or botched root retouches. The biggest challenge, however, is the application.
Most mistakes occur from over- or under-processing or simply being unable to reach the back of your head.

First, you need to understand what you've got and where you want to go: of you've got brown hair, you can't go blonde with a box color, but if you want to go from brown to rich red or the deeper side, it's possible.
To find the hair color that suits you, decide if your skin tone is warm or cool.
Look for words line 'warm' or 'golden' on the box if you're warm, while opt for 'cool' or 'ash' shades if you're cool toned.

At-home coloring products are either temporary, semi-permanent, tone-on-tone or permanent. Semi-permanent dyes tend to last 6 to 12 shampoos, tone-on-tone last 12 to 24 shampoos and permanent colors can last for months.
Remember, if your hair is very light or damaged, semi-permanent dyes will last longer, in fact they may never entirely fade.
If you want to go lighter, only a permanent hair dye can give you what you want. In general, at-home permanent color only lightens a few shades.

Going darker is easier, but keep in mind that if hair is permed, chemically straightened or damaged, the color will take fast and last longer. In this case, choose a shade a bit lighter than the color your really want.

How to Dye Your Hair at Home
When applying the dye, take time to gather your tools, including combs, clips and timer. Do a test strand first on an one inch piece of hair. If you like the result, go ahead following the directions and using the same timing you did for the rest.
Apply the color systematically, working from the bottom up, taking small sections at a time and saturating them. When the time goes off, rinse thoroughly and condition.

Highlighting kits can be tricky to use.
Follow the directions to the letter and don't create too many highlights the first time you try. Once you get the hang of it, you can add more and they will look natural.

Root retouches often give most women trouble. Part hair in sections from the hairline to the nape of the neck, from ear to ear, across the to top the head and clip in place. Apply the applicator nozzle to your scalp and squeeze color onto your roots.
Work through each section in very small sub-sections, using fingers to massage color up to where the roots end and old color begins. If you have product left, work it through the rest of your hair just five minutes before the timer goes off.

If you chose the right shade for you and applied color properly, chances are you'll be thrilled with the result. If you don't like your new look, don't try to fix the color on your own – go to a professional.
