Keratin hair treatments, popular for their smoothing and straightening effects, have become increasingly prevalent among individuals seeking to enhance the appearance of their tresses. However, concerns have arisen regarding the potential impact of these treatments on color-treated hair, highlighting the importance of understanding their effects before making a decision.

Alterations in Hair Structure

Keratin treatments involve applying a keratin solution to the hair, which is then sealed in using heat. This process fills in the hair’s cuticle, smoothing its surface and reducing frizz. As a result, the hair shaft becomes more porous, allowing color to penetrate more easily. This increased porosity can lead to changes in hair color, especially for previously treated hair.

Color Fading and Alterations

The heat used in keratin treatments can break down the pigment molecules in color-treated hair, causing the color to fade or change hue. Additionally, the smoothing effect of keratin can make it difficult for color to adhere to the hair shaft, resulting in uneven coverage and patchy results. Color may also appear darker as the treatment reduces hair volume and increases its density.

Long-Term Effects

The long-term effects of keratin treatments on color-treated hair depend on the specific treatment used and the condition of the hair. Some treatments may cause minimal color alteration, while others can lead to significant changes. Regular keratin treatments over time can accumulate on the hair, further exacerbating color fading and potentially leading to hair damage.

Hair Health Considerations

While keratin treatments generally do not cause significant damage to healthy hair, they can worsen pre-existing damage in color-treated hair. The heat and chemicals used in these treatments can dry out hair, making it more prone to breakage and split ends. Proper hair care and regular deep conditioning are essential to maintain hair health after keratin treatments.


To minimize the impact of keratin treatments on color-treated hair, consider the following recommendations:

– Consult a professional hair stylist before receiving a keratin treatment.

– Opt for formaldehyde-free keratin treatments, as formaldehyde can damage hair and alter color.

– Use color-safe shampoos and conditioners to maintain hair color.

– Deep condition hair regularly to prevent dryness and damage.

– Avoid using heat styling tools excessively after a keratin treatment.


Keratin hair treatments can have varying effects on color-treated hair, depending on the individual’s hair type and condition, as well as the treatment used. Understanding the potential impact and taking necessary precautions can help individuals make informed decisions about whether a keratin treatment is right for them while minimizing the risk of color alterations or hair damage.
