I have a uts (Ultra Thin Skin 0,03mm) unit with a blond front. So I dyed it today with a comb and it was really easy not staining the skin. I actually got some on the skin but it came of easily (dark brown color). I have now dyed it and haven´t worn it yet (I´m a lace-wearer at the moment) but OMG. The only hurdle I had with thin skin was the colored hairs goingen down between the layers in the loop. That is now gone and it looks f*** amazing. holy shit I can´t wait. It blew my mind and I haven´t even worn it yet. If this turns out the way I hope I´ll share it in this thread.
