Hi again .. I agree with mcnash there --poly strip very very easy to work with for bond/de-bonding......with that density you will have no issue with show-through at all... front hairline will be lace and poly sides/back. Some people don`t like poly as they say it`s more detectable to touch ... I honestly can`t say it`s been an issue for me ..it`s very thin really. I think it may be an issue if you use tape under it rather than glue due to the `thickness`of the tape, but really, it gives a great bond and is very easy to clean...I just peel the tape off without having to use solvents... it`s hard-wearing. Hope you enjoy your new hair when you get it.. Paul.
