I`d get some citrus-solvent such as `C-22`, `Desolv-it` or ` Remove` as Alcohol-based adhesive removers can be time-consuming to work with...some residues are quite resistant and need repeated applications, leading to frustration. For stubborn scalp residues, and in order to protect the eyes, place a sweat-band around the head [once system is off] and spray the area liberally..allow 10 -15 minutes, and the residue will be turned to a soft consistency...then wipe it off with kitchen towel and shampoo / wash as normal. You`ll develop your own preferences regarding glues/ tapes over time...depending on your individual physiology, some products will work better/worse for you than on other people --it`s one of those ` imponderables` of this wearing -game...it`s trial and error until you find what suits you best...regards.
