Does anyone tint their eyebrows at home? I've been having mine done in a salon for a few months now and it's working out quite expensive so am thinking of doing it myself at home, it looks fairly easy to do (famous last words!!) if you do it at home, what kit do you use? I've seen Refectocil online which has very good reviews...also I am sort of a medium brown, so not sure what colour to order?!
