BEST KERATIN GLUE FOR PRETIPPED HAIR

[sparklle0913]

Hi Eeryone, I am new here and love fusion hair extensions. I do them on myself as well as my personal clients/friends for the past 2 years.... but i was curious I
get my hair from visonhairextensions.com but when it comes to retipping what is the best long lasting glue out there. I use the super keratip kind off their link for 40.00. but is there something that lasts longer thanks
