I always wrap before I hang. It eliminates the redness and most of the blister problem. I hang 20 lbs for 15 minute intervals, trouble free.
My routine:
1. Apply 1/2” wide band of hypafix tape around my unit just below the coronal ridge. It both plumps the head and also serves as an anchor for the other pieces.
2. Apply 3/4” wide strip of hypafix from the band up over the top of head and down to the band. 3 of these will completely cover th head.
3. Cover these three strips using 3M Heathcare waterproof tape.
4. Wrap tight around head with Hurt Free (or any stretchable bandage). Even though the Hurt Free sticks to itself, secure with a piece of paper tape.
Then I am ready to hang. In betwee sets, it is extremely important to unwrap the Hurt Free. I leave everything else on. Then after 5-10 min. rest, I wrap again with the Hurt Free and do another 15 min. session. Best to limit to only three sessons but can be done morning and evening. I have reduced the blister problem to one in 4 or 5 months, usually when I’m not paying attention to time or when I am pushing the evelope doing 4 sessions.
Hypafix tape is available only at medical supply stores and is expensive but sure is worth it. Paper tape would be cheaper substitute. I have hung over 1300 hours starting with 6 lbs and working up, so I’ve had lots of opportunity to perfect my wrapping. I’m not saying that what I do is good for you, but just sharing what works for me.
