Never perm a color, always color a perm. In other words, always color
your hair after your perm.
If using a color glaze, use it the same day as your perm, because the cuticle layers of your hair will be more open from the perming process, and the color will penetrate more deeply into the strand of hair. The result is that the color will last longer.
If planning for permanent color, do so no longer than ten days after your perm, for the best results when coloring permed or relaxed hair.
When your home-colored hair comes out badly, always take the results to a color expert who should be able to correct the process while maintaining your hair's condition.
If you are swimming in chlorinated water, always protect your hair, especially if you have colored it. A bathing cap will do the best job, but if you have reservations and must swim freely, then wet your hair and apply conditioner before entering the water. Don't rinse the conditioner out. The reason is that your hair will be filled with the conditioner like a sponge which will provide a measure of protection from the chlorine. Without proper precautions, you could wind up with faded color at the least, and greenish hair at the worst.
If you color fine hair, it will change more quickly and become darker.
If you have been coloring your hair over some period of time, and you
want to return to your natural color, have foil highlights put in that
match your original color. This will allow a more natural transition
back to the original color.
When coloring your own hair at home, always perform a patch test. This is not merely for checking the coloring results, but to test for any allergic reactions you may have whenever using any new formula.
If your hair is in poor condition, you are better off to have a professional color your hair than to try it at home yourself.
A salon hair color product is usually a higher quality than any drugstore formula. They do a better job of moisturizing, conditioning and cleansing.
When choosing a color, pick a tone that is within two to three shades of your natural color. Otherwise, you may wind up looking like an offbeat celebrity musician.
For coloring hair the first time, some items that may be of assistance are an old T-shirt (it can be a messy process), towels and washcloths that are seconds which you don't mind staining, hair clips to section your hair and a hand mirror.
When you have achieved a color that you are pleased with, plan on recoloring every four to six weeks. Use shampoos and conditioners that are recommended for color-treated hair, to minimize fading. Watch out for long exposure to the sun or to chlorinated pools without proper protection for your hair. Don't use heavy conditioners which can remove the color.
