You lather, rinse, repeat, and unknowingly, you might also be upping your chances of heart disease. That innocent-looking shampoo bottle sitting on your bathroom shelf could be doing more than just cleaning your hair.
Thanks to a new global study published in The Lancet eBioMedicine, we now know that a silent assassin lurks in our daily grooming rituals: a chemical called Di(2-ethylhexyl)phthalate, or DEHP.
Used to make plastics flexible, DEHP is hiding in plain sight in your shampoo, your conditioner, your lotion, and that plastic food container in the microwave. But this isn’t just another story about questionable ingredients. This chemical, researchers say, is linked to over 356,000 deaths from cardiovascular disease in 2018 alone among people aged 55 to 64.
And guess which country tops the list? India, with a staggering 103,587 fatalities, nearly a third of the global total. So yes, your bathroom routine might just be a bigger health hazard than that street-side vada pav.
Why DEHP Is In Your Shampoo
So, why would anyone put a potentially fatal chemical into something as basic as shampoo? The simple answer is flexibility. DEHP is a phthalate used to soften plastics; think squeezable bottles and glossy product finishes. It is also used to stabilise fragrances, which is why your “midnight orchid rainstorm” shampoo smells the same every time.
Here’s the catch: DEHP doesn’t stay locked in the plastic. It leaches, especially when exposed to heat or moisture (ahem, like in your steamy bathroom).
Every time you squeeze that bottle or scrub your scalp, tiny traces of this chemical may enter your body. In fact, the NYU Langone Health study analysed urine samples from over 200 countries and found alarming levels of DEHP metabolites, the chemical byproducts that signal its presence in the body.
And it is not just a cosmetic problem. The researchers found that DEHP contributes to inflammation in the coronary arteries, the kind that leads to heart attacks and strokes.
According to Dr. Leonardo Trasande, distinguished paediatrician and environmental health expert based in New York City, who is also the senior author of the study, the chemical “interferes with hormones that regulate essential biological functions such as metabolism and heart health.”
The Global Capital Of DEHP Deaths
While everyone is at risk, India seems to be at ground zero. With over 103,000 deaths linked to DEHP exposure, the country recorded the highest number of cardiovascular deaths in the study. The reasons are a booming plastics industry, weak regulatory oversight, and a whole lot of DEHP-laced daily products.
Other nations like China and Indonesia followed with 33,858 and 52,219 deaths, respectively, but India’s numbers stand out like a sore thumb. Researchers also pointed to the delay in regulatory action as a major culprit. While countries like Canada and the U.S. began cracking down on phthalates as early as 2008, India only recently introduced DEHP restrictions in its food packaging sector, and even those are patchy.
Meanwhile, your average Indian consumer remains blissfully unaware, trusting that what is sold on the shelf is safe to use. Spoiler alert: it is not.
Why That Fruity-Smelling Shampoo May Be A Fragrance Bomb
Ever seen “fragrance” listed on your shampoo label? That one word could be hiding a cocktail of chemicals, many of which are phthalates. Companies are not required to disclose what goes into their fragrance mixes, so “fragrance” could mean literally dozens of chemicals, including DEHP, all bundled up in a single, innocent-sounding word.
The study warns against exactly this kind of vague labelling. According to Dr Trasande, “Reducing your use of ultra-processed foods can reduce the levels of chemical exposures.” He extends the logic to personal care products as well. If it is overly perfumed, overly glossy, or overly cheap, it is probably overly toxic.
And if you are still clinging to your fruity shampoo out of brand loyalty, consider this: DEHP is already linked to reproductive issues, cancer, asthma, and diabetes. It is even listed under California’s Proposition 65 for its potential to cause reproductive harm and cancer. So that tropical coconut breeze scent? It might come with a side of hormonal chaos and arterial inflammation.

How Industrialisation Is Killing Us Softly
The DEHP crisis isn’t just a health issue; it’s a symptom of unchecked industrialisation. Countries in Asia, the Middle East, and the Pacific accounted for 75% of DEHP-linked deaths, a telling sign of how plastic use and lax regulations are taking a toll on public health.
In India, rapid urban development and poor waste management mean DEHP is virtually everywhere – in the air, in the soil, and yes, even in your beauty routine. Ironically, the same global forces that push for cosmetic perfection – smooth hair, glowing skin, zero wrinkles – are also the ones clogging your arteries.
The study’s economic estimates are just as jarring. DEHP-related deaths are expected to cost the global economy anywhere between £510 billion and £3.7 trillion in lost productivity. That’s not just a few bad shampoo days; that’s a global health and financial crisis disguised as convenience.
Toss That Shampoo Before It Tosses You
Let’s get real. If your shampoo bottle could talk, it would probably whisper, “I’m trying to kill you, but gently.” We’ve normalised toxic ingredients in the name of beauty and convenience, and it’s literally killing us, especially in countries like India, where regulatory safety nets are full of holes.
There’s still hope, but it begins with awareness. Read your labels. Avoid products with vague terms like “fragrance.” Ditch plastic when you can, especially when it comes to food and personal care. Opt for glass containers, ceramic bowls, and fragrance-free items. As Dr. Leonardo Trasande said, reducing exposure to ultra-processed products can help minimise your chemical load, but stronger systemic action is needed too.
And if you think this is just alarmist talk, hear it from the lead author of the groundbreaking study, Sara Hyman, who issued a stark warning: “By highlighting the connection between phthalates and a leading cause of death across the world, our findings add to the vast body of evidence that these chemicals present a tremendous danger to human health.”
The next time you pick up that sleek, sweet-smelling bottle in the store aisle, ask yourself: Is this really worth the risk? Your heart and your hormones might thank you for walking away.
