Because I don't have any experience with forward ventilation. Sure I can tell them what direction but will that mean it will ONLY work the one way? My own hair grew somwhat forward, but I was able to slick it back, part it on either side, these pieces don't really work that way. Forward ventilation will let me cover hairline on bad days but will I be able to still comb it back to show hairline or will it be so set in stone and be just forward that I am too limited. It does not seem like there is anyone that has a forward ventilation with 3 to 4 inces in lenght to get some info out of...
