I think many guys use blueliner tape ...seems to give a very strong hold in many conditions.
Scalp clean up is dealt with by applying glue-melter, allowing to penetrate,then wiping it off using kitchen towel or bubble wrap . Some residue can be stubborn and require a few applications.... citrus-base melters are very good at breaking down residue.... this one is available on-line and in stores in the U.S. I think http://www.amazon.co.uk/Solv-Strength-De...144&sr=8-3

Also on this site http://www.hairdirect.com/store/Solvents-Removal.aspx scroll down to the bottom and you`ll see `c-22` citrus-based solvent.....most of the other ones would be alcohol-based.
