"Link Between Hair-Straightening Cream and Repeated Kidney Damage in Women"
A woman experienced kidney damage three times after receiving hair-straightening treatments at a salon using a cream containing glyoxylic acid. Doctors suspect the acid absorbed through her skin and reached her kidneys, causing damage. An experiment with mice showed that glyoxylic acid led to the formation of crystals in their urine, similar to those seen in people who have ingested toxic alcohol. The doctors involved in the case believe the products should be avoided and potentially discontinued from the market due to the potential dangers of using glyoxylic acid in hair-straightening or smoothing products.
