TRESemmé Shampoo Lawsuit Filed Over Hair Loss, Adverse Scalp Reactions

Lawsuit alleges formaldehyde in TRESemme shampoo cause hair loss, burns, scalp irritation and other injuries

Unilever faces a new TRESemme’ shampoo lawsuit, alleging the manufacturer falsely advertises the products as safe, while concealing information that consumers may be exposing themselves to formaldehyde and other ingredients linked to reports of hair loss, scalp reactions and other injuries.

The complaint (PDF) was filed by Holly Schafer in the United States District Court District of New Jersey late last month, indicating she suffered scalp irritation, burns and hair loss from TRESemme’ shampoo products that contained undisclosed levels of  a dangerous ingredient called DMDM hydantoin (DMDM).

The lawsuit implicates all TRESemme’ shampoo products, which Schafer claims contain DMDM hydantoin as a cheap and unnecessarily dangerous preservative.

DMDM hydantoin is a chemical that releases formaldehyde which has been shown to cause cancer and other harmful reactions when applied to the skin including itchiness, red rashes on the skin brittle hair, loss of hair and even dermatitis.

TRESemme’ Shampoo Hair Loss Lawsuit

Schafer claims Unilever TRESemme’ shampoo products are marketed nationwide with false and misleading marketing and labeling claims, specifically touting on the product labeling the TREsemme’ products “deeply nourish”, “gently cleanse” and “repair hair”.  However, the lawsuit claims customers are being exposed to DMDM hydantoin ingredients, which may cause consumers to suffer hair loss, allergic reactions, or skin and scalp irritation.

While formaldehyde-releasers are common in shampoo and conditioner, to prevent microbes from growing in water-based products, the lawsuit claims there are safer alternatives than DMDM hydantoin.

Specifically, the lawsuit states the International Agency for Research on Cancer (IARC) has classified formaldehyde as a human carcinogen, and the National Toxicology Program of the Department of Health and Human Services (DHHS) named formaldehyde as a known and definite carcinogen to humans.

Schafer claims she began using TRESemme’ shampoo products and began to experience hair loss, thinning hair, and scalp irritation during and after washing her hair. By 2021, Schafer claims she began losing abnormal amounts of her hair, with clumps of hair falling out after using TRESemme’ shampoo products, prompting her to stop using the products.

The lawsuit claims Unilever has failed to warn customers or provide adequate warning about the use of DMDM in its products, despite knowing about the side effects of DMDM and how the products have caused hair loss and scalp irritation risks to consumers for more than a decade.

The TRESemme’ shampoo lawsuit presents claims of manufacturing defects, design defects, failure to provide adequate warning and negligence against Unilever, requesting a jury trial to determine the award of both compensatory and punitive damages.

Hair Relaxer Formaldehyde Lawsuits

The lawsuit comes amid growing concerns about risks associated with chemicals in a number of widely used hair care products, following the publication of recent research that found undisclosed endocrine disrupting chemicals in hair relaxer may cause uterine cancer.

In October, researchers published findings in the Journal of the National Cancer Institute, which warned about the chemical hair relaxer cancer risks, finding that the rate of uterine cancer was nearly three times greater among women who frequently used hair relaxer chemicals, compared to women who never used the products.

The findings have ignited a series of hair relaxer uterine cancer lawsuits and ovarian cancer lawsuits to be filed by women across the U.S., claiming decades of using hair relaxers with undisclosed chemical ingredients have caused them to develop hormone sensitive cancers.

Given similar questions of fact and law raised in a growing number of complaints filed throughout the federal court system, the U.S. Judicial Panel on Multidistrict Litigation (JPML) recently determined that all hair relaxer and perm cancer lawsuits will be centralized before one judge for coordinated discovery and pretrial proceedings in the federal court system. However, if the parties fail to reach settlements to resolve large numbers of lcaims, each case may be remanded back to the U.S. District Court where it was originally filed for a separate trial date in the future.

I'm horrified by how thin my hair became in such a short period.. my hair is alarming thin at this point, and only now that I've been doing research and reading up, I came across various people having the same problem.. this is shocking!!! I will sue Tresemme if my hair doesn't grow back soon with other shampoo's.

    I've used tresemme for many years. 5 yrs ago I had beautiful thick hair. I've used tresemme this whole time and now I've experienced hair loss and scalp irritation to where it hurts so bad when I itch. Can anyone suggest a good shampoo and conditioner to use that doesn't cause these issues but makes your hair beautiful and healthy?

My youngest stopped using it and his hair is no longer falling out in large clumps.

    Started losing hair, a lot of hair and couldn't figure out why. I loved Tresseme and used it a couple years before reading an article on Tresseme being the cause of hair loss. I quit using it after I read that it could be the cause of my hair loss.

  • JenJune 22, 2023 at 12:52 pm

    I have been using Tresseme for almost a year now. I have a third of the hair I did have and my scalp is showing all over my head. I am devastated. I hope now that I quit using it, my hair will grow back. The irritation and itching has stopped. My shower drain was plugged and when I used a snake, I found most of my hair in the drain. So depressing and frustrating.

  • RebeccaJune 7, 2023 at 1:34 pm

    I used ogx products for only a couple months and immediately started loosing tons of hair. I switched to Tresseme only to continue to loose hair and I developed large bumps on my scalp that itch. One got so big I had to have it cut out. I still have pain and more bumps. I'm devastated to find out it's the shampoo and conditioner I've been using. 😭😥

    I started to lose 20 to 40 strands of my hair when I took a shower and many more in my hairbrush. At first I thought it was because I was getting older or my overactive thyroid. I tested my thyroid which showed a normal result. I, then, realized it was because of the Tresemme shampoo and conditioner I had been using for a little over a year.

I only lose 2 to 4 strands after washing my hair ever since I STOPPED using Tresemme. My hair now is just as thick, soft and full as it was before using Tresemme. I threw away the shampoo and conditioner, along with a Tresemme gel that was giving me headaches. I strongly advise to NOT use any Tresemme products.

    I have been using Tresemme hair products since 2000. My hair was always so healthy with the products I used. I noticed throughout the years that my hair has been falling out and my sculp was getting irritated. I would of never guessed it was the product, cause I am allergic to sulfates of any kind.

    For a long while I’ve been concerned that my hair was thinning and I used TRESSemme for years. Clumps of my hair fall out in the shower.
