It`s not possible to tell any person what will/won`t work for them when it comes to bonding materials. I have covered it in this recent post/thread http://forum.toplace.com/showthread.php?...ight=glues and there are many other threads in a similar vein here :

You live in a hot climate--that will have a big influence on bonding materials and how frequently you will have to debond and clean. Removal whilst the bond is still relatively ` good` will avoid a more messy clean-up...leaving a bond in place too long leads to the materials becoming unstable and ending up going into a gooey mess [hard to clean off the lace then] Hersute recommends soaking the system in Autoglym on such occasions, as you can see on his posts in the link there.Personally, I prefer to avoid having to do it in the first place, by replacing / renewing a bond regularly..that way, there is little if any residues stuck in the lace--but that`s just me...everyone has their own preference.
I don`t understand your actual issue at [3] in your post --what is the problem with the hairline ?
It`s a matter of personal preference on which part you attach first--- when I wore toppers, I always applied 2 small bits of tape at each temple-point, having first get a ` start` on the backing-paper by peeling them back slightly[for ease of removal when ready]... I then sat the system onto my head, positioned it correctly, then ` anchored` it on by peeling the papers off my 2 ` anchor-points`.... that prevents it slipping about on the head. You can simply mark your skin at the front-edge by pressing the teeth of a comb against the skin, or drawing something blunt like the plastic cover / cap of a pen across the skin--the mark will stay visible for quite a while and you can fold your system back and apply your glue inside that line...at least 2 thin coats, and you MUST allow each one to go almost dry---NEVER EVER press lace down onto wet glue . Fold your front lace down onto the glue, evenly and you should have no ripples or uneven bits. Then fold the back of the system forward onto the front bit and apply your glue to your scalp there in the same way........you`ll need to sit in front of a large mirror and use a hand-held mirror to see the back..it can be tricky until you get used to it------ or you can simply use tape/s on the poly there if you prefer ---if using tapes, just apply them to the poly before positioning it onto your head.
You need to use system-friendly shampoo / conditioner..any of the supplies-sites sell them.
I only shampoo my hair very infrequently....I do obviously clean my base by applying shampoo to it whilst it`s off my head..I just lather it on and rinse it off almost immediately......... hair is not `` dirty`` --it`s dry and lacking oils/lubricants..... a good daily leave-in conditioner applied to damp hair will help make the system ` last` longer. I use PPI Enhance [Google it for suppliers] as it also has sunscreen in it....it`s the only product I use----again....that`s just what works for me....plastering-on all types of gels, waxes and pomades leads to build-up and thus frequent shampooing/removal..that then lifts the colour and takes the ` condition` out of the hair.....
You need lace-release to free your system from your head, then Glue-melter [alcohol] to deal with residue on your scalp and /or lace...more stubborn residue needs stronger removal-products like the citrus-based C-22 which is an actual Solvent.
There`s a search-bar at the bottom of the threads -page...enter key-words there and most if not all your questions will be narrowed-down/answered.
