Sebamed Anti-Hairloss Shampoo Caused a Strong Burning Sensation

I recently purchased Sebamed Anti-Hairloss Shampoo via Instamart in Bangalore and used it for the first time today. Immediately after use, I felt a strong burning sensation on my ears. The burning was significant enough to worry me, although I have not yet consulted a doctor or used any medication or cream. I did not expect such a reaction from a dermatologically marketed product and I am disappointed and concerned about the potential effect on my skin. I request that this incident be taken seriously, that the product be examined in detail, that my payment be refunded, and that any necessary medical guidance or support be provided in case this reaction causes further problems. I also ask to be informed about how such reactions will be prevented for other consumers.
