Class Action Lawsuit Targets Monday Haircare Over Deceptive Packaging
California — A class action lawsuit has been filed against Zuru LLC, the parent company of Monday Haircare, alleging that the brand’s products are sold in misleadingly oversized packaging. The suit, initiated by plaintiff Silvia Garcia on July 25 in a California federal court, claims that consumers are being deceived by the appearance of full containers that actually contain significantly less product.
Garcia’s complaint stems from her purchase of the Monday Moisture + Hyaluronic Acid Shampoo at a Target store in May 2025. She discovered that the bottle had a considerable amount of empty space, leading her to believe she had been misled about the product’s value. “I wouldn’t have bought it or paid a premium price if I had known it was underfilled,” Garcia stated.
The lawsuit highlights what Garcia describes as a “slack-fill scam,” particularly focusing on the 12-fluid-ounce shampoo sold in opaque containers. According to the complaint, these containers prevent consumers from accurately assessing the amount of product they are purchasing, creating an unfair advantage for Monday Haircare over competitors who provide transparent labeling.
Garcia argues that even consumers who check the net weight before purchasing are likely to be misled by the size of the container, which suggests a greater quantity than what is actually inside. The lawsuit cites previous California court rulings that have found similar slack-fill claims to be valid and suitable for class action treatment.
Garcia seeks to represent all consumers who purchased underfilled products from Monday Haircare in the past four years. She is pursuing claims under California’s Unfair Competition Law, False Advertising Law, and Consumers’ Legal Remedies Act. The plaintiff is asking for class certification, damages, restitution, and an injunction to prevent the company from selling underfilled products in the future.
In a broader context, this lawsuit is part of a growing trend of legal actions against beauty and personal care brands. Recently, Farouk Systems faced allegations of falsely advertising its CHI and BioSilk products as made in the United States and containing natural ingredients.
The Monday Haircare class action lawsuit is officially titled Garcia v. Zuru LLC, Case No. 5:25-cv-01908, and is currently pending in the U.S. District Court for the Central District of California.
As consumers become increasingly aware of packaging practices, this case raises important questions about transparency and fairness in the beauty industry. What are your thoughts on the allegations against Monday Haircare? Share your opinions in the comments below.
