Eyelash tinting

[Carodee]

Hey everyone,
I am just wondering if anyone knows if eyelash tinting oxidant is the same with every brand? I've used Refectocil in the past but then got a different brand but am finding my eyes have a bad reaction to this new one so was going to go back to refectocil. But the thing is I still have a lot of oxidant in this other brand and wondering if it will a) mix well with Refectocil and b) if I should change oxidant as well as I'm not sure if it's the colour or oxidant my eyes are reacting with.
Sorry it's a long winded question. Any help would be much appreciated.

It's never recommended to mix brands, they won't have been tested and you have no idea how they will react together......never worth taking the risk with eyes in my opinion.
