I'm going to a salon to get it cut in. I was warned about ordering ORWG in the winter but users have told me as long as its not international the shipping shouldnt ruin it. But what about it sitting on my front door step while im at work? If i cant order ORWG in the winter what glue can I use? Everyone seems to use ORWG. Do i need Knot sealer? Does back2natural stain the base?
