Yann, if you are happy with the glue you are using, you simply need to increase the frequency of your de-bond / re-bond ... two weeks is quite a long time ....if you are sweating a lot, I`m surprised your glue is holding up for that [long] time ..... in warm weather and if you do a lot of exercise, naturally, sweating will increase and will have a negative effect on any material [ Glue or Tape] Next time you remove your system, and after you have cleaned your head, you could spray anti-perspirant on your scalp..this can help to an extent, but you probably need to go for a weekly routine of replacing your glue. You can also use `` scalp protector`` as this provides a barrier between your skin and tape/ glue http://www.amazon.com/Walker-Scalp-Prote...B001JKRNX2 It`s also a good idea to leave your system off overnight once in a while to allow your pores and skin a ` break` from adhesive material...will help avoid possible irritation /redness.... regards for now!
