Hey coppersilver! Welcome to the LHC!
I am currently sitting with the first part of the treatment (underside and length) in my hair. I had put my catnip in an empty 600mL coke bottle (all I could find) and used the method of pouring it into my hand then putting it on my hair. I forgot to let it warm up to room temp first. I found it very hard to put on my hair. It dripped a lot, I probably got more on the floor than my hair it's still dripping underneath the shower cap a bit. I think for the second part I will use a bowl to catch it then dunk my head in the bowl. Off to find a bowl.
