Vichy Anti-Dandruff Shampoo Worsened My Scalp Condition

I ordered a Vichy shampoo advertised as effective against dandruff and eczema, but after using it for a week, both conditions have worsened significantly. Despite paying a high price for this product, it has failed to deliver on its promises and has instead aggravated my scalp issues.

I am extremely dissatisfied and feel misled by the product's claims. I expect Vichy to address this issue promptly and offer a solution. If no action is taken, I will file a formal complaint with the Consumer Rights Authority. Customers deserve effective products and accountability for such situations. I look forward to a response from your team.
