L'oreal — Loreal darkest brown hair color issue

Hi,

I use to color my hair with Loreal darkest brown (number-3). On 29th Nov 2020, I mix the color paste with the given solution. At the time of mixing, the color was not like always. After some time my hands started burning and I use the same on my head at same time. White marks observed in my fingers. I have attached the same for reference.
Expiry of the product is in 2023 .

I destroyed the solution immediately. I have no allergy with this product. But the first time I observe this. Please look into this.

Thanks,
abhay
