Hi garaboy.... no..just go for a lace front.... poly can be very visible there as the density is graduated [lighter] at the front and also, if/when shedding occurs as it eventually does over time, it will be too visible....lace is the way to go at the front. I always wore poly sides/back in my topper days...I think it`s very easy to work-with for newbies as it`s so easy to clean and it`s very robust. The only thing with poly is , when detaching, you have to use your alcohols `under`it.....there`s no point in spraying lace-release down onto it as the poly is impervious and the liquid will not get at the glue/tape under it...a good method is use a little plastic syringe, and spray little darts of alcohol through the hair/lace just inside the edge of the poly--where it joins the lace..that will seep under it and loosen the hold. Just de-bond the front lace as normal and fold it back..then when you `meet`the poly, spray a little alcohol there and let it `work`for a minute...you can gradually peel the system back, spraying more alcohol as you go, until it`s fully de-bonded. Be careful of your eyes when spraying . Poly comes in different widths....my last ones had 1-inch width.... I`d go no lower than 3/4 of an inch and no higher than 1 inch....depends on what you`d like yourself.....some people reckon that because the hair is put into the poly differently [ injected or looped] and hair is tied in by hand onto lace, that it can affect the overall `look`as the hairs can `lie`differently on the head..... I never ever had a problem with it..I just got injected hair on the poly and it was fine. One of the other advantages of poly is it `seals` the edge of the lace and prevents it from fraying ....one of the disadvantages is it can be a little more detectable to touch at the edge than lace.... I think any system --no matter what material-- can be detectable if a person really ``went looking`` but chances are slim enough usually....I think poly can be a little more detectable if tapes are used at the very edge as this can `raise`the poly slightly compared to glue, but don`t fret over it.... we can `over-think` some of these issues...in reality, you`ll find what works best for you. Once you get used to wearing, you could decide to go all-glue or some guys use tape `inside`the poly and glue at the very edge so it`s less likely to be felt...to be honest, I`d find that very tedious to be doing all the way around....I`m pretty lazy !! A few strips of tape here and there for me and I`m good to go !
