The head of a girl is swollen because of his hair dye
The French girl decided to buy the dye and use it, without making sure to test the sensitivity and non-impact, which led to significant negative results, as the shape of the girl aged 19 years, and became a ball, as well as the inability to breathe after large head size significantly, “I have done something stupid and I want to warn others not to act like me,” said the girl after recovering from the disaster.
EVERY day thousands of people colour their hair, but an increasing number are discovering that chemicals found in hair dyes can cause allergies, headaches, swellings and even cancers. DAVID HURST examines the possible causes and effects.
What are the dangers ?
ON contact with the scalp, up to 60 per cent of what is placed on the skin is absorbed into our bloodstreams. The chemicals found in hair dyes can trigger anything from allergies, swelling, itching, coughing, headaches, pustules, sneezing, breathlessness and rashes to rheumatoid arthritis and cancer with bladder cancer rates in women who dye their hair twice that of women who stay natural.
The carcinogenic chemicals build up in the bladder before being excreted, and can damage bladder cells. Links have also been established between dyes causing Non-Hodgkin’s Lymphoma and breast cancer.
Others using dyes have died from anaphylactic shock due to a serious allergic reaction.
An American report claims dye could cause birth defects in unborn children when absorbed through a pregnant mother’s scalp.
Who does it affect ?
HAIRDRESSERS are at obvious risk simply because they handle so much of it.
However, if you use a permanent hair dye every four to six weeks, in a dark colour on grey roots, you could also be in the highest risk category.
This is because permanent colours, particularly darker ones, contain the most concentrated amount of chemicals, used to make colour long-lasting.
Anyone who uses a hair dye is at potential risk.
Which dyes are most dangerous?
ALL hair dyes contain some form of ammonia which swells the hair to make it porous so it can absorb colour, but it is a skin-irritant, causing anything from mild itching to uncomfortable burning.
Para-Phenylenediamines are used in many dyes as they are most effective at colouring hair, and many people are allergic to them.
Other dye chemicals which have been known to cause allergic reactions are Ammonium Thiolactate (a neutraliser), parabens (preservatives), stearic acid (an emulsifying agent) and pentetate pentasodium (a binding agent).
Anything that lightens hair contains peroxide, which strips the hair of its natural pigments, but can also corrode the skin and be a lung irritant.
Despite the fact that there are many different brands on the market, the ingredients are similar in all dyes.
What if I still want to dye my hair?
PROTECT yourself from chemicals you know may be harmful by reading labels carefully. Leave the maximum time possible between dyeing sessions. Leave the dye on for the shortest amount of time possible and rinse it off extremely well afterwards.
Highlights and lowlights are the safest option because the hair is wrapped in foil and the tinting brush can go virtually to the end of the hair shaft, but does not need to touch the scalp.
Beware if a chemical stings or burns when applied, and you should always avoid having dye applied if you have a cut or scratch on your scalp.
One safe method is to carry out a patch test first at home or ask your salon to do so 48 hours before your hair appointment. Some doctors even feel this should be a legal requirement.
If you do a test at home, put a small sample of the dye mixture on your arm, beneath a nonallergenic plaster for two daysEven if you have a patch test with no effects, ensure you drink a litre of water afterwards to dilute the carcinogenic chemicals that may pool in the bladder (and it is best, for this reason, that you have your hair dyed in the morning, leaving you plenty of time to excrete any toxins during the day).
