mcat45, while alcohol will release the lace from tape/glue, I have found over time adhesive will accumulate in the hair side of the unit, a homegrown knot sealer, lol. It takes a while, but the hair at the base will become clumped together. You will need a citrus solvent or something different than alcohol to dissolve it. This can be done by soaking it off your head in a container, or on your head by soaking the unit where the tape/glue attachment is before detachment. I used to wrap a sweatband or bandana around my head and liberally douse my attachment area with citrus solvent for a half hour to dissolve the the adhesive as much as possible whenever the build-up needing dealing with. Alcohol is for quick release, and just neutralizes the adhesive.
