I dont use anti perspirant so cant comment on that. Is the scalp protector really dry when you apply the piece?


Another thing to check

run your finger on the lace just before you apply ST30.. It should be absolutely absolutely dry. If it is moist/oily/has traces of glue then it Wont Attach well to the ST30.

If there is a bit of moisture left on the lace side of piece then invert it and use a hairdryer to dry it before applying the ST30
