Chemical Hair Relaxers Carry an Increased Risk of Uterine Cancer

Hair relaxer


Chemical hair relaxers have been widely used by individuals seeking straighter, ‘more manageable’ hair for decades. However, recent studies have raised concerns about the potential health risks associated with these products. In this article, we will explore the link between chemical hair relaxers and an increased risk of uterine cancer, backed by research and study information.

  1. The Hair Relaxer Connection:

    Chemical hair relaxers contain a group of chemicals known as endocrine-disrupting chemicals (EDCs). These substances have the potential to interfere with the body’s hormonal balance, which, in turn, can have adverse effects on health.

  2. Uterine Cancer Risk:

    A study published in the International Journal of Cancer in 2012 examined the association between the use of hair relaxers and the risk of uterine leiomyomata (fibroids) and uterine cancer. The research found that African American women who used hair relaxers had an increased risk of developing uterine fibroids, and, to a lesser extent, uterine cancer. The study noted a higher risk among those who used relaxers at an earlier age and with greater frequency.

  3. Endocrine Disruption:

    The EDCs found in chemical hair relaxers, such as phthalates, parabens, and other chemicals, have been shown to disrupt hormone regulation. This disruption can lead to various health issues, including changes in estrogen levels, which are known risk factors for uterine cancer.

  4. Hormonal Imbalance:

    Uterine cancer is strongly influenced by hormonal imbalances, particularly elevated levels of estrogen. EDCs can mimic estrogen in the body or interfere with the body’s ability to regulate hormone levels, potentially contributing to the development of uterine cancer.

  5. Disproportionate Impact on African American Women:

    The risk of uterine cancer associated with hair relaxer use appears to disproportionately affect African American women. This can be attributed to the higher prevalence of hair relaxer use in this demographic.

  6. Regulation and Awareness:

    While some countries and regions have implemented regulations on the use of certain chemicals in cosmetics, including hair relaxers, the awareness of the potential risks and the availability of safer alternatives need to be further promoted.

  7. Safer Hair Care Practices:

    In light of these concerns, individuals may consider safer alternatives for hair care, such as natural hair treatments and products that do not contain EDCs or harmful chemicals. Additionally, regular health check-ups and screenings are crucial for early detection and prevention of uterine cancer.


The use of chemical hair relaxers has long been associated with cultural and aesthetic choices, but emerging research suggests that they may come at a cost to women’s health. The link between chemical hair relaxers and an increased risk of uterine cancer, particularly among African American women, highlights the importance of informed decision-making and regulation in the cosmetic industry. To protect women’s health, it is essential to raise awareness about the risks and promote the use of safer hair care alternatives.
