A Deep Dive Into Your Hair Straightener: Chemical By Chemical

Sleek, glossy tresses that are portrayed in advertisements and on social media don’t tell you the entire story. Behind the scenes, several complex chemical processes work in tandem to tame your ruffled hair texture. 

Hair straighteners and relaxers rely on a cocktail of ingredients to address curls, from powerful detanglers and flatteners to preservatives and protective coatings. But, under the superficial sheen, risks may lurk.

According to TorHoerman Law, several consumer watchdogs have raised concerns over certain compounds found in popular straightening products. Some have links to disorders in lab studies, while others have been deemed carcinogenic.

In this article, we will examine the common chemical additives–parabens, BPA, formaldehyde, metals, and cyclosiloxanes–and explain their purposes alongside potential red flags. By comprehending exactly what goes into the products many use on a constant basis, you will have the power to make informed choices and safeguard your health.

Chemical by Chemical

​The scientific community sounded an alarm after researchers at the National Institute of Environmental Health Sciences delved into the hair care habits of over 30,000 women.

Their findings were unsettling: women who relied on chemical hair straightening products, using them at least four times a year, faced more than double the risk of developing uterine cancer.

Several lawsuits have been filed against big brands like L’Oreal, Dark & Lovely, and Revlon for their negligence in not informing their customers about the possible health effects of using their haircare products.

You can file a hair straightener cancer lawsuit if you can prove a direct link between your health concern(s) and the repeated use of hair straighteners.

This stands as a stark reminder of the potential health implications of prolonged use of hair products. In this section, we will dive deep into the ‘toxic’ chemicals that form the backbone of hair straighteners.

A. Parabens

The growing concern about environmental chemicals and their link to breast cancer has cast a spotlight on parabens, a group of preservatives used in everyday products. They belong to a class of endocrine disruptive chemicals (EDCs).

Parabens are widely used in cosmetics as they inhibit mold, yeast, and bacteria growth in hair straightening products. However, consumer groups have raised questions for years about whether chronic topical exposure or accumulation over time impacts hormone regulation or increases cancer risks.

They lurk everywhere, from your morning lotion to your favorite shampoo, even finding their way into food and medicine. Once absorbed through your skin or digestion, they make themselves at home in your body, showing up in tissues, blood, and even breast milk. This constant exposure has scientists asking crucial questions about their role in breast cancers.

Some paraben forms appear more concerning than others. Research links long-chain parabens like propylparaben or butylparaben with endocrine disruption at high doses in lab models. However, larger and better-controlled human studies on direct health outcomes remain limited.

Consumers these days demand “paraben-free” options as awareness spreads. Although there are a few paraben-free alternatives in the market, evaluating, testing, and marketing new products takes time.

B. Bisphenol A (BPA)

BPA belongs to a group of endocrine-disrupting chemicals that interfere with natural hormone activities in the body. The Environmental Protection Agency (EPA) raises a red flag about Bisphenol A (BPA), highlighting its potential to mimic and mess with your body’s natural hormones.

For instance, it can mimic estrogen behavior, which may disrupt their production, how your body responds to them, and even the hormone’s overall functioning.

This chemical agent is frequently used in the production of polycarbonate plastic and can be found in baby bottles, the inner coatings of hair straighteners, and regular electronic items, to name a few.

Specifically, BPA poses potential concerns due to leaching risks from heated appliances over time. Repeated exposure allows it to accumulate, and numerous studies link it to problems like reproductive disorders, increased cancer risks, and developmental issues in fetuses.

The FDA imposed bans on baby bottles containing BPA plastics in 2012. Many appliance makers now highlight their products as “BPA-free” to address the growing demand for alternatives. However, the substitutes bisphenol-S (BPS) and bisphenol-F (BPF) may carry similar disruption risks, according to emerging evidence.

Formaldehyde

Formaldehyde is a common ingredient in hair-smoothing treatments. The pungent gas can cause eye and respiratory irritation during product use in the short term.

However, the biggest threat from this gas is to the people who are exposed to its fumes for long hours a day, for many days. Long-term exposure to its toxic fumes has been linked to cancer.

Amidst the growing outrage against formaldehyde and its uses, the FDA (Food and Drug Administration) banned formaldehyde-containing hair straighteners on October 6, 2023.

The growing awareness among consumers, coupled with financial and legal pressure on manufacturers, can bring about a necessary change.

Metals

Trace levels of nickel, aluminum, lead, arsenic, and other metals often exist in hair straighteners without appearing on labels. They may leech from metal components of heated appliances over time or get introduced during manufacturing.

Nickel and chromium are common allergens. They can trigger skin rashes upon contact. According to research, some brands have alarming levels of developmental toxins like lead and arsenic in their products.

Since research on metal traces remains scarce currently, voids exist in fully quantifying exposure levels and direct health consequences. More oversight and formal investigation into the heavy metal content of such everyday personal products will influence reformulations or restrictions.

Cyclosiloxanes

Siloxanes like cyclotetrasiloxane (D4) and cyclopentasiloxane (D5) impart silky textures, lubrication, and heat protection when present in many hair straighteners. However, D4 and D5 do not break down and can persist in the environment, leading to their bioaccumulation in aquatic species.

D5 can cause issues in the respiratory tract, liver, and nervous systems. As a result, silicone-containing hair products are subject to tight regulations in the EU.

Making Informed Choices

When it comes to selecting hair straightening products, you may find yourself facing many unknowns and an evolving landscape of chemical safety debates. However, a few practical principles offer reference points amidst the uncertainty.

To begin with, you have to try to reduce exposure frequency. Whenever you plan on using hair care products like straighteners, adhere to the application guidelines. Even gentler ingredients can pose some risks with chronic, long-term use.

Second, carefully vet product claims and brands for transparency about ingredients and testing. Some reputable manufacturers voluntarily disclose potential contaminants and back claims with scientific evidence. Using their products can alleviate your product-related anxieties.

Progress requires coordinated efforts between scientific funding agencies, lawmakers, and manufacturers to better control ingredients of concern while supporting innovations for safer alternatives.

While debates continue raging, you, as a consumer, can contribute through critical evaluation of claims, shifting buying preferences, and pressuring oversight via activism. With persistence, the market will adapt to address risks, advance testing capacities, and meet the demand for peace of mind when it comes to personal product safety.
