Khaberni - Permanent hair dyes raise increasing health concerns due to their content of compounds that may cause severe dermatological allergies and are linked by research to potential hazardous effects.
Medical warnings have recently increased regarding the health effects associated with permanent hair dyes, due to their content of "para-phenylenediamine" (PPD), the primary compound responsible for color fastness and resistance to washing. Despite their cosmetic effectiveness, research indicates they are associated with a range of risks, from dermatological allergies to the potential for increased cancer risks.
The skin can absorb limited amounts of PPD during use, but this amount might be sufficient to cause allergic reactions, notably contact dermatitis, swelling, redness, and blisters accompanied by severe itching. Estimates show that about 1.5% of users may develop an allergy to this substance, and the percentage may rise to 6% among those suffering from skin conditions such as eczema.
On the front of potential long-term risks, the International Agency for Research on Cancer classifies repeated professional exposure to hair dyes as "possibly carcinogenic," while current evidence does not indicate a confirmed danger to personal users of the dyes.
Despite this, limited indicators have been observed linking frequent use to certain types of cancer, including estrogen receptor-negative breast cancer and basal cell carcinoma, without conclusive final results.
In cases of acute poisoning resulting from ingestion, the affected individual may experience rapid failure of vital organ functions, and a serious swelling in the neck and respiratory tract could occur, making it a life-threatening situation.
With increasing awareness of these risks, companies have turned to offering PPD-free products, relying on alternatives like PTDS which relatively reduce allergenicity, though about half of those allergic to PPD may also react to it.
Experts recommend conducting an allergy test 48 hours before using any hair dye, with the necessity for professionals to use gloves and adhere to safety guidelines to reduce the chances of exposure to risks, according to the British newspaper "Mirror."
