Can keratin hair treatments cause kidney damage?

There is no concrete proof that keratin hair treatments cause kidney harm. Keratin treatments are typically used to make hair smoother, shinier, and more manageable by temporarily covering the hair shaft with a protective layer of protein. However, some keratin treatments involve formaldehyde or formaldehyde-releasing compounds, which are used to help keratin attach to the hair.

Formaldehyde is a recognized irritant that can cause health concerns, particularly when breathed in high doses. It has been linked to respiratory difficulties, eye discomfort, and skin responses. In rare situations, continuous exposure to formaldehyde has the potential to cause some forms of cancer.

Concerns concerning kidney damage are often raised due to the possibility of formaldehyde exposure, as the kidneys are responsible for filtering toxins from the circulation. However, there is minimal evidence that keratin hair treatments cause kidney harm.

To reduce any possible hazards linked with keratin treatments, it is important to:

• Choose products that have low formaldehyde content or are formaldehyde-free.
• Ensure proper ventilation during the treatment process to reduce inhalation exposure.
• Follow safety precautions provided by the manufacturer and consider professional application in a salon.
• Be aware of any potential allergic reactions or sensitivities to the ingredients in the treatment.
