ANY unit lace or skin can be made to hold for a week or more with the methods out there. The issue is CLEAN UP... I like a quick turn around so I use less adhesive. Even so I can get a week easily out of a walker taped front and got to be glued ot Walker taped back and I do not tape the full perimeter... I only apply tape to the corners of the back and a small piece in the lower center None over the ears. I find less tape holds just as well.
I cut all the pieces in half lengthwise as well...No need for 1" wide tape.



I wear a full cap now and have have used a poly strip with SFS.....
Next order was ALL French...... I prefer the french over SFS because its hearty and just as "invisible"
Then I ordered 100% Thin skin.....used white glue on front and sides..tape on nape of neck

And now ordered all thinskin with french lace front and sides.....

I prefer the poly because the Got to be Glue is really a great attachment for those of use who itch at the neck.... I have found tape irritates the nape of my neck after a week or so.. but not the side or top! I use Walkers on the top and side with the lace units and
either clear scotch tape with a cut blue liner on top of it or Got to be Glued.

Full caps are getting pricey but they can last awhile as one does not have to sleep in them with the Got to be Glued attachment.

I will say the all thinskin I recently put on shedded badly in one area. I never had one shed this bad...makes me wary about ordering another but i like the skin......
