Doctor Warns of Hair Dye Allergy Risks
Doctor Vladimir Bolibok warned that para-phenylenediamine (PPD) in hair dyes can cause allergic reactions ranging from mild skin irritation to life-threatening anaphylaxis.
Consensus
- Para-phenylenediamine (PPD), a common ingredient in permanent hair dyes, is a major allergen.
- Contact allergy to PPD affects about 1% of the general population, and up to 4–6% among tested patients.
- The most common reaction is allergic contact dermatitis, with symptoms appearing 12–48 hours after dyeing, sometimes after several weeks.
- Symptoms include redness, itching, scaling, and blistering of the scalp.
- More severe reactions include urticaria and Quincke's edema, which can occur shortly after contact.
- Anaphylaxis, though rare, has been reported and can be life-threatening.
- Medical consultation is advised if itching, redness, or swelling occurs after hair dyeing.
