Hi Mr. Hair.... high temperatures can [obviously] lead to yourself being more prone to elevated levels of perspiration.....the combination of moisture and heat can affect bonds....try using `scalp protector` [it`s on Debbie`s site] to lay down a `base`/foundation...it`s for oily scalps or where high humidity is an issue. Some people find supertape can irritate the skin so just keep an eye on that if you decide to use it.....I wonder would `Ghost bond` work better? It can be a trial and error thing at first..so many things can affect a bond, individual body physiology and local weather conditions..... hopefully you`ll overcome this ...regards, Paul.
