Ever since the first woman looked into a
polished surface and decided that her appearance
would be greatly benefited by certain
sophisticated modifications, the feminine sex
has been tampering with its natural beauty.
Among the first of the features to receive attention
has been the hair, long known as
“woman’s crowning glory,” and now merely an
added source of income to the tonsorial artist.
The first hair dyes were made from vegetable
substances. Then came metallic, chemical
compounds, and more recently the synthetic
dyes largely derived from coal tar products.
Among the vegetable dyes, henna is the best
known example, but indigo wood extracts, sage
and camomile have also been popular. Hair
dyed with henna is light red, but one hour will
make brown hair extremely red and give to
white and blond hair a quite peculiar orange
color, extremely artificial and unattractive.
The wood extracts and camomile produce all
sorts of peculiar colors. They are reasonably
safe, but suffer from the disadvantage that
the dyes are difficult to prepare and the result
not especially permanent. Most of these dyes
do not penetrate the hair shaft, but merely
coat it so that their repeated use tends to make
the hair quite brittle.
Metallic dyes include combinations of lead,
silver, copper, tin, and other metals. All metallic
hair dyes, according to Dr. McCafferty, who
has written extensively on the subject, must be
considered as potentially dangerous when used
for any length of time. The material may be
absorbed into the body and the person so saturated
with metallic poison that he develops
serious symptoms.
Most of the dye substances offered on the
market and advertised in publications are combinations
of henna with metallic substances.
The dye action depends principally on the pyrogallol
and on the metal, with just enough henna
present to permit the manufacturer to use the
name “henna dye.”
The most common dye used today is the synthetic
drug known as paraphenylene-diamine.
Many persons are especially sensitive to this
drug and develop severe eruptions following
its use. In certain instances, eruptions on the
back of the neck and on the arms follow the
wearing of fur dyed with this substance. In
Germany, the dye must always be marked with
a “poison” label and most European countries
have followed that example.
In this country, legislatures are only beginning
to consider legislation of a similar character.
If a person is sensitive to paraphenylene-diamine,
his scalp and face will begin to tingle
and itch after its application, and this will be
followed, in from 10 to 12 hours, by a swelling
and blistering of the skin. The eyelids also
may swell to such an extent that the person
is unable to see.
Most of the cosmetic establishments use this
dye for their work. The treatment given by
most physicians consists in wet dressings of
boric acid solutions and in small doses of X-ray
to the region concerned. Following the subsidence
of the preliminary symptoms, soothing
creams are applied to the tissues. Dr. McCafferty
points out that every substance used as
a dye remover is a dangerous poison, which,
if it does not injure the person using it, at
least makes the hair extremely brittle. It is
his belief that dye removers should be legislated
out of the beauty shops.
