Hair is one of the most important aspects of ones appearance. Aside
from having the right hair cut and style, what also matters in the
overall manifestation of the hair is color; and since hair contributes
greatly to a persons looks, the more captivating and fascinating
hair becomes when one tries on a change in hair color.
The use of hair dye makes it possible for people who want to have their hair color changed. There are three categories in which hair dye products can be classified in to. These include the Permanent, the Semi-permanent, and the Temporary hair dyes.
Contrary to its name, the Permanent
hair dyes are not really permanent. They are only the very long
lasting type, which may seem to be permanent. For this reason, the
application of the permanent hair dye is a common misnomer as it
is entails more than one application. The permanent hair dye utilizes
an oxidizing agent, often called as the developer, and an alkalizing
ingredient as part of their ammonia or an ammonia substitute.
When one decides to use a semi-permanent
hair dye, he or she must consider that this type of hair dye
last longer than the temporary
hair color, which takes about 8-14 shampooing to get rid of
the color. The compounds used in developing a semi-permanent
hair dye are combined to deposit color on the hair shaft. This
way, the hair color is not lightened. It also utilizes the miniscule
molecules than those of the temporary tinting formulas. For this
reason, the semi-permanent formula is able to penetrate the hair
shaft. In addition, the main difference between the permanent and
the semi-permanent hair dye is the use of a developer. In the case
of a semi-permanent hair dye, there is no developer may be used
with heat for penetration.
Usually, this temporary hair color
is used to give brighter, more vibrant shades or colors. These colors
may include orange or red, which may be difficult to achieve when
using either a permanent or semi-permanent color. Because the pigment
molecules are unlike the permanent or semi-permanent hair dye, the
coating may be easily removed by shampooing.
