have you ever thought about how long your hair could grow from a logical standpoint?

i know this sounds contrary to popular belief, but i think my hair has the potential to grow for at least a decade. the answer is in the hair dye. for those of you who dye your hair, especially if you typically let it grow out for at least 12 inches if not more, then you can estimate your potential maximum hair length from your shed hair rate. so if you dye your hair, and you notice three years or so after you've dyed your hair that the majority of those strands you dyed are still over your head and have not been replaced by sheds, imagine the implications for your potential hair length mathematically speaking! if you still have red or whatever color you dyed there comprising the majority of your strands, that means that realistically your hair can grow for at least double if not triple or more what your current length is. i thought about that while noticing that my dyed strands, three years later, were still dominant- that if i wanted to "grow them out", it would take FOREVER for them to shed out naturally all the way. that means that if you want looong hair, you're more than likely not confined to just the 2 to 8 year average that scientists have proposed. what do you guys think?
