Natural remedies for straight hair have gained popularity in recent years, as people look for alternatives to chemical hair straightening treatments. While routine hair-straightening procedures can lead to minor side effects like skin irritations, there may also be serious complications like kidney-related problems. Doctors in the UAE have highlighted the potential risks associated with keratin treatments and urge people to be informed about the harmful effects before undergoing such procedures.
In a recent study published in The New England Journal of Medicine, doctors reported a case involving a woman who suffered kidney damage following a hair-straightening treatment at a salon. The use of various chemicals in hair straightening treatments and hair dyes can occasionally trigger side effects in individuals sensitive to them. Small amounts of these substances may be absorbed into the bloodstream, potentially leading to allergic interstitial nephritis — a serious condition characterized by severe kidney failure.
Symptoms such as weakness, joint pains, skin rash, and reduced urine output should be promptly addressed and thoroughly investigated. Early diagnosis and appropriate treatment can reverse the condition, enabling full recovery for the patient. Dr. Mohammad Shamma, a specialist nephrologist at Zulekha Hospital, Dubai and Sharjah, emphasizes the importance of being aware of the signs of kidney damage to help diagnose, treat, and prevent kidney-related issues caused by hair treatments.
Dr. Swathi Dembala, a specialist dermatologist, warns against routine hair straightening using chemical products, as they can result in damage to the hair shaft. She specifically points out the effects of glyoxylic acid and glycolic acid, which are commonly used in keratin-based hair-straightening treatments. These acids have a strong hair straightening effect and inadvertent systemic absorption may lead to toxic effects on the kidneys. Caution is advised when using products containing these acids available in the market.
While Dr. Shamma has not come across instances of kidney failure resulting from hair straightening treatments during his professional tenure in the UAE, he stresses the importance of being vigilant about the signs of kidney damage. Laboratory tests for kidney function remain the only way to early detect any defect in kidney function. It is crucial for individuals considering hair straightening treatments to be informed about the potential risks and to consult with healthcare professionals before undergoing any procedures to ensure their safety and well-being.
