it came loose because its attached to hair and not skin. spray lace release on where the tape is attached to your hair and it will come loose, then shave the hair off and reapply the st-30 and you should be fine.
attaching over hair never gives an optimum result.......if your hair blocks the tape from touching your skin in any way, the bond isn't good. remember, these tapes are made to be attached to skin, not to hair.
