I can't be sure but I'll say I won't ever be split free. I have way too many hairs to determine that. I think even with S&Ds, trims, and things like the spilt ender there is no way to tell because there unless you go follicle by follicle to determine each hair's status then there will always be come stray shorter hair that may look like a split because its not in line with the rest, but who's to say if its not at a different growth phase?
