The U.S. Food and Drug Administration is weighing a proposed ban on formaldehyde and several other chemicals found in many chemical hair straightening products. Department experts warn that certain ingredients can trigger allergies, respiratory irritation, and even cancer. This information is reported by Health News.
For people with curly hair, salon services often labeled as keratin straightening or keratin treatments are used to simplify styling and achieve a sleeker look. The process typically involves applying specialized formulas to the hair and then using heat to help the ingredients penetrate the strand.
A notable share of straightening products contains formaldehyde or related compounds. When these substances are heated, they can release a strong, pungent gas that is colorless but potentially harmful if inhaled.
Research into the health effects of formaldehyde indicates that individuals who regularly undergo this type of hair treatment may face increased risks. Some studies have linked frequent exposure to uterine cancer and potential fertility challenges, though findings may vary by study and exposure level.
In addition to cancer risks, inhaling formaldehyde vapor can adversely affect the respiratory system. People may experience coughing, wheezing, shortness of breath, nasal congestion, sneezing, eye irritation, and nausea after exposure.
Experts also note that women with tightly curled hair, and particularly those with darker complexions, might encounter higher exposure levels. The hair structure can necessitate repeated treatments, which could raise cumulative exposure to formaldehyde and related chemicals.
There is also historical reporting that some household chemicals could be linked to developmental concerns in adolescents, highlighting broader considerations about chemical exposure in homes and personal care products.
Regulators emphasize the importance of reading product labels, seeking ventilation during applications, and choosing alternatives when possible. Consumers may want to consult with dermatologists or licensed cosmetologists about safer styling options and the potential long-term effects of frequent chemical straightening. When doctors or regulators evaluate risks, they consider the balance between the desire for effective cosmetic results and the need to protect health over time.
In the ongoing discussion, it is acknowledged that exposure varies with product formulation, application method, and individual sensitivity. It is advisable for users to be mindful of symptoms after treatments and to seek medical advice if respiratory issues, skin irritation, or other health concerns arise.
