|Allergic Reactions To Hair Dye On The Rise, Warn Scientists|
February, 16 2007
London, A new study has scientists warning that as an increasing number of younger people turn to dying their hair, they now face the risk of increased allergic reactions to hair dye.
The study, which appeared in this week’s BMJ, warned that allergic reactions may lead to dermatitis on the face, as well as facial swelling in severe cases.
More than two thirds of hair dyes currently contain para-phenylenediamine (PPD) and other related agents that cause allergies.
The sensitization from the ingredients in hair color can extend to sensitization of other products of same or similar composition, including but not limited to the dye used in textiles, sunscreen, rubber, and/or certain medications.
And even though all hair color products, except for temporary color, require a patch test before application to determine if the client is allergic to the product, dermatologists report anecdotally that the frequency of positive reactions to PPD on patch testing is increasing.
During the 20th century, allergic reactions to PPD became such a serious problem that it was banned from hair dyes in Germany, France, and Sweden.
Current European Union legislation allows PPD to comprise up to 6% of the constituents of hair dyes on the consumer market, but no satisfactory or widely accepted alternatives to these agents are available for use in permanent hair dye. (ANI)
