Hair Relaxers

By The Numbers

Recent studies and statistics highlight the significant health risks associated with the frequent use of chemical hair straighteners, especially among Black women.

• 2022 NIEHS Study: Found that women who used chemical hair straighteners more than four times a year had double the risk of developing uterine and ovarian cancer compared to those who did not.
• Impact on Black Women: Non-Hispanic Black women have the highest rates of uterine cancer deaths and are more likely to be diagnosed with aggressive subtypes. The study noted that Black women are more affected due to higher usage rates of these products.
• 2023 Boston University Study: Confirmed that postmenopausal Black women who used chemical hair straighteners long-term had a high risk of developing uterine cancer.
• FDA Action in 2023: Proposed a ban on hair relaxers containing formaldehyde and similar ingredients due to health concerns.

Hair Relaxers Link to Cancers

Many hair relaxers are packed full of harmful chemicals that can alter hormones and may increase the risk of hormone-sensitive cancers. When using hair relaxers, these chemicals can enter the body through burns and cuts on the scalp, potentially leading to health issues. Gynecologic Cancers linked to hair relaxers include:

Endometrial Cancer

Endometrial cancer, also known as uterine cancer, starts in the inner lining of the uterus (the endometrium). The uterus is where a baby grows during pregnancy. Symptoms include vaginal bleeding after menopause, bleeding between periods and pelvic pain.

Ovarian Cancer

Ovarian cancer begins in the ovaries, fallopian tubes, or the peritoneum (the lining of the abdomen). Symptoms include vaginal bleeding or unusual discharge (especially post-menopause), pelvic pain or pressure, abdominal or back pain, bloating, feeling full quickly or difficulty eating, and changes in bathroom habits (frequent urination or constipation)

Uterine Cancer

Uterine cancer is one of the most common gynecologic cancers and includes endometrial cancer and uterine sarcoma. It primarily affects women who are going through or have gone through menopause. Symptoms include unusual vaginal bleeding or discharge and pelvic pain or pressure.
