Ducray Extra-Doux shampoo did not suit my sensitive scalp and caused itching. How can I properly document an adverse reaction?

If Ducray Extra-Doux shampoo caused scalp itching despite being marketed as gentle. How to properly document an adverse reaction:

Even mild shampoos designed for sensitive scalps can cause itching if there is an individual intolerance to certain ingredients. Itching, tingling, or burning after washing your hair is not normal and should not be considered an adaptation, especially if the symptoms worsen with repeated use.

How to document the reaction properly:

Stop using the shampoo immediately

Record the symptoms and when they appeared

Keep the bottle with the batch number and expiration date visible

If necessary, have the scalp condition documented by a specialist

It’s important to clearly show that the reaction occurred specifically after using the product. Even without a medical report, such cases may be valid grounds for a complaint if the shampoo is marketed as suitable for sensitive skin.

If the seller or brand ignores your request, filing a complaint on Xolvie helps officially document the adverse reaction, obtain a response, and warn other users about possible side effects of Ducray Extra-Doux.
