I'm using walker no shine currently. I've never been able to get more than 6 days out of this tape before it started peeling off and once i even got 7. The shortest time ive gotten is 4 days and on the fourth night it acctualy unattached itself from my head like half way in my sleep. But currently i'm 9 and half days and its still really strong. I've played football, sat out in the heat and even washed my hair atleast 3 times since attachment. I dont have a problem with it ofcourse :] but i havent done anything different and i dont understand why the attachment is so much stronger now :S. Like when uni starts i dont want to leave it on too long thinking it will be alright only to stop over at someones and find its loosened. Really weird :S
