The Research at a Glance

• Chemical straighteners & uterine/endometrial cancer: Frequent use (more than four times per year) has been associated with more than double the risk of uterine cancer compared with non-users. A frequently cited figure shows lifetime risk by age 70: approximately 1.64% in non-users vs. 4.05% in frequent users. These concerns are especially acute for Black women, who, on average, use these products more often.
• Occupational hair dye exposure & bladder cancer: Hairdressers and barbers exposed to dyes and processing agents over many years face a 40–50% higher risk of bladder cancer than the general population. The International Agency for Research on Cancer (IARC) classifies occupational exposure to hair dyes as “probably carcinogenic to humans.” Poor ventilation and lack of protective measures can compound that risk.

Why These Products Can Be Risky

Straighteners/relaxers: Certain formulations may contain or generate endocrine-disrupting and potentially carcinogenic compounds during application and heat treatment, raising concerns for the uterus and ovaries.

Permanent/oxidative dyes: Some dyes contain aromatic amines, a class with known bladder carcinogens; repeated, unprotected exposure can increase cumulative dose over a stylist’s career.

Who’s Most at Risk?

• Frequent straightener users, especially those starting at younger ages.
• Salon workers (stylists, colorists, barbers) with years of daily exposure, particularly in spaces with inadequate ventilation or inconsistent use of gloves, aprons, and eye protection.

Symptoms to Watch For

• Uterine/endometrial cancer: Abnormal uterine bleeding (especially after menopause), pelvic pain/pressure, unusual discharge.
• Bladder cancer: Blood in urine, frequent urination, urgency, pain with urination, back/pelvic pain.

If you notice symptoms, see a healthcare provider promptly and share your product use or occupational exposure history.

Practical Steps to Reduce Harm

• Limit exposure: Reduce frequency of chemical straightening; minimize skin contact; follow manufacturers’ directions carefully.
• Workplace protections: Wear gloves; ensure good ventilation; use closed mixing systems when possible; implement salon safety protocols and training.
• Stay informed: Track ingredient lists and evolving research; discuss personal risk with your clinician.

Legal Landscape: Do You Have a Claim?

Manufacturers and employers have a duty to design reasonably safe products, warn about known risks, and provide safe workplaces. You may have a viable claim if:

• You developed uterine, endometrial, ovarian, or bladder cancer after prolonged use of straighteners or long-term occupational exposure to hair dyes; and
• You were not adequately warned about risks or were exposed without appropriate protections at work.

---

How to Strengthen a Potential Case

• Document your health: Keep medical records, pathology reports, and notes of symptoms and diagnoses.
• Save product proof: Receipts, photos of packaging/labels, and brand names you used (including salon records).
• Track exposure history: Dates, frequency, salon roles/tasks, ventilation conditions, and safety equipment used.
