Although absorbtion through skin is very small,
chemicals stream during dyeing process can have impact on babies,
especially hair dyes containing ammonia.
In the past, dyeing hair was for those who
have gray hair early. Nowadays, dyeing hair is used for many people, even for
children; and there are about 70% of women in the world dyeing hair at least 1
time.
Depending on existing time, dye is divided
into 3 groups: temporary, semi-permanent, and permanent. Temporary dye creates
change of color quickly and simply. Besides, it is easy to remove in the first
time of washing. Temporary group is produced with many kinds of products such
as shampoo, spray, lotion, foam, and so on.
Do
not dye hair in the first three months of pregnancy.
Semi-permanent makes color’s change be
longer and fade gradually after a few times of washing. This group is made in
many kinds of products as lotion, gel, cream, and foam.
Chemicals that create colors can penetrate
into peel of hair, but they will spread little by little on surface of hair and
disappear after washing (about 6 – 8 times).
Permanent dye is used the most at present
because of its stability and consumers only take it once a month.
When using dye, you need to read carefully
instructions. Dye is one of the chemicals, so it can make body have allergy
although very small rate of population is impacted by dye. Most of the allergic
reactions with dye are hypersensitivity.

The reaction usually happens at contacting
area. In a few cases, reaction may be more serious and spread more widely such
as facial edema. Allergic reactions often appear including rash, edema, water
acnes, and itch at skin’s area contacting with dye.
Dye contains hydrogen peroxide or ammonia
can lead to irritation, so you need to read carefully the instructions and put
them out of children’s reach.
Moreover, dye includes most oxidizers with
intensive alkalinity, so they can change structure of hair. These alkaline
peroxides will break hydrophobic surface of hair.
This layer is considered as hair protecting
system; therefore, the destruction will make hair injured, not revive and make
users have unexpected feelings such as dry hair, being difficult to brush,
losing shine, and reducing temperature dramatically (easy to break).
Hair
broken off or cut off will not be acceptable
According to American Gynecological and
Obstetrical Society, hair dye is quite safe for pregnant women because it is
absorbed through skin very little. However, many healthy experts recommend that
women should not use permanent dye in the first three months of pregnancy.
Although absorbing through skin very
little, chemical stream emits during process can affect babies, especially hair
dye contains ammonia.
