In December 2020, we received multiple inquiries from Snopes readers asking us to examine the accuracy of reports and social media posts that claimed users of two variants of TRESemmé shampoo had filed a class-action lawsuit against the manufacturer, Unilever, over the alleged inclusion of an ingredient that causes hair loss.
On Dec. 3, Facebook user Shevelle Finney recounted her alleged experience of hair loss in a post that was shared more than 250,000 times. She wrote:
…I have very long thick curly hair that is now half the thickness it was this time last year. It has been falling out by the brush full and in the shower. I just chalked it up to the stress. I’ve used Tresemme shampoo for years it’s the only thing that tames my hair. Well guess what… I got a phone call from my mother tonight telling me to stop using it. She just got an email about a new class action lawsuit against Tresemme shampoo for having ingredients in it that make your hair fall out.
