Ontario woman claims TRESemmé Keratin Smooth Shampoo causes hair loss.

An Ontario woman claims that TRESemmé Keratin Smooth Shampoo products lead to scalp irritation, blistering, swelling, dry hair, and even significant hair loss.

The woman filed a nationwide class action lawsuit hoping to represent all Canadian consumers who purchased TRESemmé Keratin Smooth Shampoo products, including the brand’s Keratin Smooth Shampoo and Keratin Smooth Colour Shampoo. Lead plaintiff Morris claims that the products are defective and contain harmful ingredients that lead to scalp injuries and hair loss.

Morris claims that TRESemmé Keratin Smooth Shampoo products were her “go-to” haircare purchases between 2018 and 2020. She says she bought the shampoo at a Walmart in Greater Sudbury on several occasions; however, in the summer of 2020, she says she began experiencing scalp irritation and hair damage and loss.

Morris points to social media posts of others complaining about the products as well as a class action lawsuit lodged in the US alleging TRESemmé Keratin Smooth Shampoo causes hair loss. She says she stopped using the product, but her hair hasn’t grown back. In addition, Morris claims that her hair is still brittle, dry, damaged, and thin and she often wears hats because she is embarrassed by her hair.

The class action lawsuit alleges that Unilever Canada and other defendants misrepresented the TRESemmé Keratin Smooth Shampoo products, failing to warn Morris and other consumers about the serious risks and negative side effects associated with some of the ingredients included in the shampoos. Specifically, Morris says that prolonged use of the Keratin shampoos can result in severe damage to users’ hair and scalp.

The products allegedly include hydrolyzed keratin protein, marula oil, and/or argan oil. Morris says that, according to TRESemmé Keratin Smooth Shampoo marketing, these ingredients were supposed to leave her with “soft and smooth hair.”

On the contrary, claims Morris, the ingredients in the TRESemmé products form formaldehyde, a well-known allergen and carcinogen, when they mix with water. Specifically, a preservative called DMDM hydantoin is known as a “formaldehyde donor” and is used in the product, alleges the class action.

The lawsuit alleges that Unilever and the other defendants have known about the danger of DMDM hydantoin for years. The class action lawsuit cites a $10.2 million class action settlement that concerned similar allegations against Suave over the ingredient in 2012. In addition, the plaintiff points to thousands of consumer complaints about the products.

Further, numerous safe alternatives exist, says the plaintiff. However, Unilever continues to use the dangerous ingredient and advertises the safety of its TRESemmé Keratin Smooth Shampoo products.

    I got it for my wife and Approximately 5years ago, a friend of mine had gone to a hair stylist for keratin treatments to smooth and straighten her unruly hair. She loved the result, and suggested it to me, but it was very expensive. she then noticed a commercial on TV promoting Tresemme Keratin smoothing products. She was so excited to try it that I bought every product in the line – shampoo, conditioner & styling products. When her hair started to get dry we assumed it was due to change of seasons and continued using the full line of keratin products. Then, she started losing hair, and I mean losing handfuls. I lost almost 50% of my hair within 6 months.

    Because I have very curly hair, I was always looking for ways to smooth it out and get rid of frizz. Approximately 5years ago, a friend of mine had gone to a hair stylist for keratin treatments to smooth and straighten her unruly hair. She loved the result, and suggested it to me, but it was very expensive. I then noticed a commercial on TV promoting Tresemme Keratin smoothing products. I was so excited to try it that I bought every product in the line – shampoo, conditioner & styling products. When my hair started to get dry I assumed it was due to change of seasons and continued using the full line of keratin products. Then, I started losing hair, and I mean losing handfuls. I lost almost 50% of my hair within 6 months. My hair stylist suggested cutting off 7 inches and started me on a hairloss product line. I ended up using up the rest of he shampoo and conditioner after finishing the expensive salon products. I have struggled for years to get my hair healthy again, living with bald spots, wearing hats and hair bands and still to this day have very thin, dry/brittle hair. I would really appreciate being added to this class action.

    Hi, I’d like to know how to join the lawsuit. I have suffered severe hair loss, dry itchy scalp, and breakage which caused me to think I had thyroid issues. I seen my primary care doctor and everything checked out okay. Then realized it was the shampoo and conditioner I was using which was tresseme keratin. Unknowingly before I even knew it was being recalled I even bought more of this product.

    1. Juliana says:

    1. Sheila O'Callaghan says:

      I have been using TRESemme shampoo for the past twenty years. I have switched types of
      TRESemme shampoos over the years, usually when they drop it from the line. I’m currently using Healthy Volume. It does not give me volume as my hair is fine and flat all the time and tends to look oily about half way through the day. There is a fair amount of hair lose. My scalp is always itchy and I develope blisters at the base of my hair line in the back. They are very itchy and last weeks on end. They are worse March and April and then again in Sept. and Oct. Thought I had head lice, but I didn’t and haven’t.
      Please add me to this class action suit.

  10. Judy Rossi & Michael Veraldi says:

    My husband and I used TRESemme shampoo & the conditioner for many years. Our hair has become very thin and brittle. All this time I thought there was something wrong with me. After we shampooed and conditioned our hair it never looked smooth. Once our hair dried it looked very dry and frizzy!!.. I also began to find hair all over the bathroom and our pillows. And experienced itchy scalps all the time. My husband did have very thick hair. I was shocked to find all this hair on my husband’s pillow also!!!.. Please add us to this Law Suit.
    We will NEVER use this produced again!!..
