There is no hair loss lawsuit against amika. As of mid-2026, no class action or individual suit has been filed alleging that amika products cause hair loss or scalp injury, and the brand is not named in the wave of shampoo litigation that has targeted companies like DevaCurl, OGX, TRESemmé, and Olaplex. Amika has, however, faced two separate legal and regulatory matters worth knowing about: a 2025 recall of one of its shampoos over bacterial contamination, and a California Proposition 65 pre-suit notice concerning a chemical in another product.
The Mirrorball Shampoo Recall
In January 2025, amika voluntarily recalled its Mirrorball High Shine + Protect Antioxidant Shampoo. The recall covered all sizes and lot codes sold during 2023 and 2024 after testing found potential contamination with Pluralibacter gergoviae, a bacterium associated with unsanitary manufacturing conditions. The UK’s Office for Product Safety and Standards found the product failed European cosmetic safety rules and posed a “microbiological risk.”1GOV.UK.

About 95,000 units were affected in Canada alone, and the shampoo had also been sold through Sephora, Space NK, Cult Beauty, and TK Maxx.2Recalls-Rappels Canada. Amika Mirrorball High Shine + Protect Antioxidant Shampoo Recalled Due to Microbial Contamination Amika told customers to stop using the shampoo even if it looked normal and to return it with proof of purchase for a refund. By late January 2025, the company had received 48 reports of foul odor and two reports of irritation or allergic reaction in Canada. Amika stated that “there have been no reported serious adverse health events associated with using this product.”3Cosmetics Business.

Amika attributed the contamination to a third-party manufacturing site, not a formulation issue.3Cosmetics Business.

The Proposition 65 Notice on the Wizard Detangling Primer
On July 8, 2024, a consumer advocacy group called the Initiative for Safer Cosmetics filed a 60-day notice of intent to sue amika, its parent Bansk Group, and Sephora USA under California’s Proposition 65. The notice alleges that the amika Wizard Detangling Hair Primer contains diethanolamine (DEA), a chemical listed under Prop 65 as a carcinogen, without the warning California law requires.5California Office of the Attorney General. 60-Day Notice of Intent to Sue – Amika the Wizard Detangling Hair Primer
A Prop 65 notice is a pre-litigation step, not a filed lawsuit. The statute requires 60 days’ notice before a private enforcement action, and violators can face penalties of up to $2,500 per day per violation. Whether the notice resulted in a formal complaint, a settlement, or a private resolution is not established in available records. The alleged concern is cancer risk from an unwarned chemical, not hair loss.
How Amika’s Ingredients Compare to Brands That Have Been Sued
Most of the shampoo hair loss litigation of recent years, much of it fueled by TikTok, has focused on formaldehyde-releasing preservatives, especially DMDM hydantoin. That was the ingredient theory behind cases against TRESemmé, OGX, Mane ‘n Tail, and DevaCurl.6GoodRx. Can Ingredients in My Shampoo Cause My Hair to Fall Out
Amika’s shampoos do not contain DMDM hydantoin. Ingredient lists for the Normcore Signature Shampoo, the Mirrorball shampoo, and the Perk Up Dry Shampoo show no formaldehyde-releasing preservatives; the products use phenoxyethanol and ethylhexylglycerin as their primary preservative system.7EWG Skin Deep.

The EWG Skin Deep database does flag some amika ingredients. The Normcore Shampoo contains lilial (butylphenyl methylpropional), which EWG scores 8 out of 10 for allergy and immunotoxicity concerns, and lyral, which the EU has restricted over sensitization risk.7EWG Skin Deep.

What a Hair Loss Claim Against Amika Would Have to Show
A consumer bringing a hair loss claim against any shampoo brand generally relies on product liability law. That means showing a defect in design, manufacturing, or warnings, and pursuing the claim under either negligence, which requires proving the company failed to exercise reasonable care, or strict liability, which focuses on whether the product was defective and caused harm regardless of the company’s care.13Cornell Law Institute. Products Liability Hair product suits often add false advertising and breach of warranty theories, arguing the brand marketed a product as safe while knowing about a risk. Defendants respond that the consumer misused the product, that the injury came from a pre-existing condition, or that the ingredient is widely used and regulator-approved.
For amika specifically, none of the ingredient theories that drove the shampoo litigation of the past several years line up with its formulations, which is the most likely reason no hair loss case has been filed. If you experienced hair loss or scalp irritation you believe is connected to an amika product, that is a matter for a medical evaluation first and, if warranted, a personal injury attorney; there is currently no class action to join.
