 Here
are several basic types of hair dyes on the market. These are.....
|
Temporary hair colors
|
Which
are applied in the form of rinses, gels, mousses, and sprays. They coat the
surface of the hair
and usually wash out within two or three
shampoos.
|
|
Semipermanent
dyes
|
Penetrate into the hair shaft, but not as deeply as
permanent dyes. Although semipermanent dyes do not rinse off with water, they
do fade and wash out of hair after about five to 10 shampoos.
|
|
Long-lasting semi-permanent
|
A newer
category that promises to last through 24 washings. In general, the more
permanent the color the better the grey coverage and the more accurate the
color. This is a better choice than the semi-permanent if you have a lot of
gray to cover.

Permanent hair dyes
|
Especially those that lighten and color in one process. These
formulations penetrate deeply into the
hair shaft
and don't wash out.
Permanent hair-coloring products consist of two components that are packaged
separately and mixed together immediately before application. One package
contains a solution of hydrogen peroxide (usually 6%) in water or a lotion
base. The other package usually contains an ammonia solution of dye
intermediates and preformed dyes—called couplers. The primary intermediates
are ortho or para diaminobenzenes, aminohydroxybenzenes, and to a lesser
extent dihydroxybenzenes that develop color on oxidation. If you are trying to
cover gray, you'll have the most success with this group of dyes.

Research has shown that some of the substances in hair dyes are readily absorbed
through the skin and scalp during application.
The new study’s findings indicated that women and men who dye their hair
frequently might be at increased risk for hematopoietic cancers. The early
studies showed an association between hair dye use and increased risks for
multiple myeloma (cancer of cells in the bone marrow), non-Hodgkin’s lymphoma
(cancer of the lymph system), and leukemia (cancer of blood-forming cells) in
both sexes, and ovarian cancer in women. Almost all the early studies indicated
that increased risk might be restricted to long-term or frequent hair dye users,
particularly users of dark hair dyes.
First timers should:-
|
-
Pick a color as close
to your natural color as possible.
-
Worry less
about brand name and more about desired color.
-
Choose a
temporary or semi-permanent formula.

If you color your hair at home, please be sure to read the instructions
carefully and do a patch test before hand. This is especially important if you
change from one brand to the other. Medications you are taking can also make you
more sensitive to hair color, which may result in itching or burning of the
scalp.
A
safer way to cover grey or change your own natural color is to have highlights
and lowlights added, so the actual product never touches the scalp.
