Medical Mystery Solved: Hair Dye Triggers Severe Anaphylactic Shock
A 61-year-old man suffering from repeated fainting spells and severe swelling was diagnosed with anaphylactic shock caused by artificial hair dye.
A dramatic medical mystery at an Indian hospital ended with a surprising and life-saving diagnosis: a 61-year-old man with a history of heart disease was rushed to the emergency room after losing consciousness twice in a short period. Comprehensive tests of his brain and heart showed nothing unusual, but at the same time his blood pressure plummeted rapidly and severe swelling began to deform his face. Only a re-examination of his actions in the days leading up to the incident revealed the cause of the dangerous deterioration: routine use of artificial hair dye that triggered severe anaphylactic shock.
The incident began with a sudden feeling of nausea, after which the patient lost consciousness for three minutes. Shortly after waking up, he fainted a second time for another two minutes. His family testified that no involuntary movements or loss of bowel control were observed—signs that might have indicated a seizure or epileptic attack. Given his medical history, which included heart disease, the medical team's immediate suspicion focused on a stroke or cardiac event.
Comprehensive Testing and Rapid Deterioration
The patient underwent a series of urgent tests, including an MRI to examine brain structure and an EEG to check electrical brain activity, alongside tests to rule out infections and heart attacks—but all came back completely normal. While the tests provided no answers, his condition deteriorated: he developed alarming swelling around one eye that rapidly spread to the other and the rest of his face, and his blood pressure dropped consistently to critical levels, despite massive fluid infusions in the intensive care unit.
"The turning point in the diagnosis occurred when the doctors began to thoroughly investigate every detail of the man's daily routine."
Hair Dye as the Culprit
It then emerged that two days prior to fainting, he had used an artificial hair dye, immediately followed by persistent itching on his scalp, neck, and face. The patient attempted self-treatment, taking cetirizine—an antihistamine for allergy relief—for two days while spending prolonged hours under the blazing sun. This combination of data completed the full picture for the doctors: a stormy systemic allergic reaction.
The man was rushed to emergency treatment, which included immediate administration of epinephrine, alongside steroids and antihistamines. Due to the persistent drop in blood pressure, the team had to continue continuous adrenaline infusions for 16 hours until initial stabilization. Only after three days of intensive care did his blood pressure return to normal, and the facial edema gradually subsided until the danger passed.
