I`ve tried it now ..well I must say I`m impressed.. now like anything, as this is my first time using it, I went `easy` / light on the perimeter where the poly strip is... went a bit heavier on the front hairline which is lace.. I also coated the whole scalp [ middle etc.] and I must say...the hold in the centre is incredible--- if you catch the hair and try to prise it off the head..not a hope !! It`s practically the same as `normal`glues..... the poly part is not stuck right to the very edge, but I deliberately only applied a light layer there ....the front is really good too...I`ll experiment with a heavier layer tomorrow..... will enjoy experimenting with this ...I`ll leave the system bonded on tonight for sleeping ...just to see what way the bond `behaves` overnight..... really impressed so far though...
