A 20-year-old woman from Hangzhou, China, experienced severe health issues after two years of monthly hair bleaching and dyeing. The repeated chemical treatments led to the development of purple spots on her body and kidney inflammation. Doctors diagnosed her with purpura nephritis, a kidney condition caused by allergic purpura. The purple dye she had used was identified as a strong allergen contributing to her condition.

The Incident:

Two years ago, the woman began bleaching and dyeing her hair every month to achieve vibrant celebrity-inspired colours. She frequently touched up her roots and changed her hair colour with each session. To achieve lighter shades, she sometimes bleached her hair up to three times in one sitting. Last month, she used a new purple hair dye. Three days later, purple spots appeared on her legs. Initially, she dismissed them as mosquito bites. Within a week, the spots spread across her body. She also experienced stomach pain, joint swelling, and dark, coffee-coloured urine.

Diagnosis and Treatment:

Alarmed by the symptoms, she sought medical attention. Tests revealed high levels of protein in her urine and signs of kidney damage. Doctors diagnosed her with purpura nephritis, a kidney condition caused by allergic purpura. The reaction occurs when immune complexes build up in the kidneys, leading to inflammation. The purple dye she had used was identified as a strong allergen.

Doctors told her that treatment would only be effective if she shaved off all her hair. The recommendation left her devastated, but she eventually agreed after encouragement from her family and medical team.

Recovery and Precautions:

Following four weeks of treatment, the purple spots faded, and her urine protein levels improved. She was discharged from the hospital with instructions to avoid all hair dyes in the future. Doctors also advised her to undergo monthly check-ups and urine tests to monitor her recovery.

Beyond skin and scalp irritation, repeated exposure to chemical hair treatments increases the risk of hair thinning, chronic dermatitis, and even serious health conditions like acute kidney injury or hormone disruption.

Conclusion:

This incident serves as a cautionary tale about the potential health risks associated with frequent use of chemical hair dyes. While cosmetic products can enhance appearance, it's crucial to be aware of their ingredients and potential side effects. Individuals should exercise caution and consult healthcare professionals if they experience adverse reactions to such products.
