TRESemmé Keratin Smooth Shampoo: Smooth it or Lose It

More News on the Tresemme Keratin Shampoo Class Action Lawsuit

Update: As Bills become Laws, investigations become Lawsuits!

Now, hair products such as shampoos are synonymous with bathing. A person’s hair is, usually, very important to them, and many people go above and beyond to find haircare products they not only love, but trust.

Tresemme has been a name in hair forever, but recently a new TRESemme Keratin Shampoo Class Action was filed after it was alleged that these products have a preservative in them called DMDM hydantoin, also known as a leach formaldehyde, which activates when it comes into contact with water.

A Closer Inspection Revealed the full Story

Upon inspection of the company’s online marketing and the labeling of the product, there are allegations that the company represented the TRESemmé products as having keratin, a protein naturally found in hair which deeply nourishes, gently cleanses, and repairs all types of hair.

The lawsuit alleges that the company failed to inform their customers of the risks linked with using a strong chemical like this on their hair and even went as far as claiming their product is perfectly safe to use.

There are also claims that Unilever did not warn their customers that a preservative among the ingredients of their products causes hair loss and contributes to scalp irritation. The claims also state that there’s nothing on the packaging that informs or warns people of the risks of using DMDM hydantoin on the hair and scalp.

Similarly, the lawsuit also mentions that DMDM hydantoin is a formaldehyde donor, that when it is added to water-containing cosmetics, it prevents the growth of microorganisms by releasing small amounts of formaldehyde.
