Does Keratin Hair Treatment Lead to Kidney Damage?

Does Keratin hair treatment causes kidney damage?

Keratin hair treatments have become increasingly popular as a means to achieve smooth, shiny, and frizz-free hair. However, concerns have been raised about the potential health risks associated with these treatments, including the possibility of kidney damage. In this blog, we will explore what keratin is, why people opt for keratin treatments, the potential risks to kidney health, and how to minimize any potential harm. Read on to know more!

What is Keratin?

Keratin is a type of protein that is a key structural component of hair, skin, and nails. It helps protect cells from damage and stress, contributing to the strength and resilience of these tissues. In the context of hair care, keratin treatments involve the application of a keratin-infused product to the hair, which is then sealed in with heat, typically using a flat iron. This process aims to smooth the hair shaft, reduce frizz, and enhance shine.

Why Do People Opt for Keratin Treatments?

Keratin treatments have gained popularity for several reasons:

1. Frizz Reduction:

One of the primary reasons people choose keratin treatments is to combat frizz, especially in humid climates.

2. Smoothness and Shine:

The treatment leaves hair looking smoother and shinier, improving its overall appearance.

3. Manageability:

Post-treatment, hair is generally easier to style and manage, saving time and effort in daily hair care routines.

4. Long-lasting Results:

The effects of a keratin treatment can last for several weeks to a few months, making it a convenient option for those seeking long-term hair smoothness.

What are the Potential Risks of Keratin Treatments?

While keratin treatments can offer significant cosmetic benefits, they are not without risks. One of the primary concerns is the use of formaldehyde or formaldehyde-releasing chemicals in some keratin products. Formaldehyde is a known carcinogen and can pose various health risks.

Formaldehyde Exposure

Formaldehyde exposure can occur during the application and heating process of keratin treatments. This exposure can lead to:

Respiratory Issues:

Inhaling formaldehyde fumes can cause respiratory problems, including coughing, wheezing, and difficulty breathing.

Skin Irritation:

Contact with formaldehyde can result in skin irritation or allergic reactions.

Eye Irritation:

The fumes can irritate the eyes, causing redness and discomfort.

Can this Treatment Damage Kidneys?

The primary concern regarding kidney damage stems from the potential systemic absorption of formaldehyde or other harmful chemicals. Although there is no direct evidence linking keratin treatments to kidney damage, long-term exposure to high levels of formaldehyde can potentially impact kidney function. Read on to know the risk factors:

Toxin Accumulation:

Kidneys filter waste and toxins from the blood. Exposure to high levels of toxic chemicals, including formaldehyde, could overburden the kidneys and impair their function over time.

Increased Risk for People with Preexisting Conditions:

Individuals with preexisting kidney conditions or compromised renal function may be more susceptible to potential harm from toxic exposures.

What are Some of the Best Ways to Prevent Damage?

If you choose to undergo a keratin treatment, there are several measures you can take to minimize potential risks:

Choose Formaldehyde-Free Products:

Opt for keratin treatments that explicitly state they are free from formaldehyde and formaldehyde-releasing agents.

Ensure Proper Ventilation:

Make sure the treatment is performed in a well-ventilated area to reduce inhalation of any fumes.

Limit Frequency:

Avoid frequent keratin treatments to minimize cumulative exposure to any potentially harmful chemicals.

Professional Application:

Have the treatment done by a licensed and experienced professional who can ensure proper application and safety measures

Patch Test:

Conduct a patch test before the full application to check for any adverse reactions.

Hydrate and Detoxify:

Drink plenty of water and maintain a healthy diet to support kidney function and overall detoxification.

Consult Your Doctor:

If you have pre existing kidney conditions or any health concerns, consult your healthcare provider before undergoing keratin treatments.


Keratin hair treatments can provide significant cosmetic benefits, making hair smoother, shinier, and more manageable. However, it is crucial to be aware of the potential health risks associated with these treatments, particularly the use of formaldehyde and other harmful chemicals. While there is no direct evidence linking keratin treatments to kidney damage, taking preventive measures can help minimize any potential risks.

By choosing formaldehyde-free products, ensuring proper ventilation, limiting the frequency of treatments, and following other safety guidelines, you can enjoy the benefits of keratin treatments while protecting your health. If you have any underlying health conditions or concerns, always consult with a healthcare professional before proceeding with any hair treatment.
