So I am newly qualified last week and want to check how you deal with a patch test when you use a brand line that doesn’t have the patch test packs like LVL. I have got the step 1 and step 2 in the little individual sachets. If I open them to do a patch test on a client, can I sellotape up the packet and then use the product on the client 24 hours later or does it ‘go off’ I don’t want to waste product if possible but may not be thinking logically here either lol.
