Eyelash tint patch testing

[Mrsspider]

Hi,

I have recently qualified in lash tinting, I had hoped to use Refectocil tint but having read their instructions and after being advised advised by the tutor too I would need to patch test before every treatment, even in repeat clients. This is obviously not going to work out to be honest and so I am hunting a good tint that does not require this, who uses which brand xxxx
