Recently I put black henna and after few days I noticed it didnt penetrate my skin. Instead, it felt like a kids tattoo, so I couldn't do my wouzou.
So, when I noticed that , I started to perfom my kaza namaz

But the problem is that I already put black henna before, and I never noticed this. Therefore, I am confused whether I have to perfom my qaza namaz for the other times I had black henna on my hands?

Was that henna which prevent the water from reaching the skin?
