The Ultimate at-Home Hair Color Guide

How to Do Allover Color
To get the exact results you want, pore over the
"before" shades on the box labels when shopping—
and make sure your starter color is a match.
Total Time Needed: About one hour
Step 1: Don't wash hair for two days before you dye
—you want your scalp's natural oils to act as a
barrier against irritation, says Clairol Professional
celebrity colorist Kiyah Wright. If you have
supersensitive skin, add a packet of Sweet'N Low to
the dye to help stop the drying effects of ammonia.
Step 2: Do a strand test first by applying color on a
small section. This will help you work out timing.
Your hair texture will factor in here: The finer it is,
the faster it'll lighten—you may need five to 10
minutes less than the box says; if you have coarse or
dry hair, you can go by the recommended time.
Step 3: Read, reread, and follow the box instructions
to a T. (Exception: Don't apply color from roots to
ends in one go; see step 4.)
Step 4: This tip helps get even color every time when
you're dyeing your whole head: First, apply dye a
half-inch away from your scalp and work toward
ends (the heat from your head makes the color
develop faster at the root). Then, halfway through
the processing time, go back and cover your roots.
