Thanks for sending that post. It’s a problem experienced by others too. Ultra Hold is the strongest glue and normally lasts about 10-14 days and longer. So when you only get a few days from that it’s unusual. A couple of suggestions. First, swab your scalp with a towel dipped in rubbing alcohol or Pure Adhesive remover. This will completely clean your scalp of any residue and provide clean skin for a good bond. If the skin isn’t completely clean no glue or tape will stick for long. It has to be clean. And while you’re at it swab the bottom of the base to remove any adhevise that might be accumulated there too. Second, try Walker No Shine tape. It is very strong and should give you at least a week hold. That too after swabbing your scalp. A clean scalp is a must.
A skin unit typically has a longer bond time with all else (glue/tape) being equal. Why? You have more surface area to adhere to than lace so it has more area to stick to.
Best,
