Have you heard of DMDM hydantoin hair loss? It’s rumored that popular hair care products formulated with this ingredient can actually damage the hair and scalp, leading to hair thinning. In fact, class-action lawsuits have been filed against certain popular hair brands for including this ingredient in their products. But is there any truth to this claim? Keep reading to learn more about DMDM hair loss.
What is DMDM Hydantoin?
DMDM hydantoin is a type of antimicrobial compound called a formaldehyde releaser or donor. DMDM hydantoin releases small amounts of formaldehyde, which prevents bacteria and mold from growing.
So, what is formaldehyde? Formaldehyde is a strong-smelling, naturally-occurring chemical that is often used in industrial cleaning products thanks to its ability to kill germs. It is also commonly used as a preservative in funeral homes and medical labs.
Although formaldehyde is a common ingredient, there is evidence that it’s a carcinogen (cancer-causing compound). According to the American Cancer Society1, exposure to formaldehyde has been shown to cause cancer in laboratory test animals.
But because formaldehyde is so effective at preventing the growth of bacteria and mold, DMDM is commonly added to hair care products like shampoo to preserve them and increase their shelf life. DMDM hydantoin is a very popular preservative and is found in many widely available shampoos, conditioners, and other water-based hair products.
Does DMDM Hydantoin Cause Hair Loss?
Most of the evidence that DMDM causes hair loss is anecdotal. Scientifically speaking, the jury is still out on whether DMDM hydantoin causes hair loss.
“According to scientific research, DMDM hydantoin is a safe cosmetic ingredient when used at regulated levels,” says Gretchen Friese, a trichology consultant. “The amount of formaldehyde released from DMDM hydantoin is about the equivalent to the amount that naturally occurs in one medium-sized apple or pear.”
However, if you have sensitive skin, you may want to steer clear of this ingredient regardless. A 2011 study2 indicated formaldehyde-releasing ingredients like DMDM hydantoin can cause allergic contact dermatitis and contact eczema in people who are allergic to formaldehyde.
The good news? There are plenty of other preservative ingredients on the market, and it’s easy to find products that are formulated without DMDM hydantoin. Just make sure to check the label before purchasing or using a new beauty product.
