Even if we were to use the argument that knowing how many hairs you shed a day can help you estimate how many years it can take for each of the 10K hairs to eventually shed and therefore an estimate of how long your terminal time is
*, then:
For someone who loses 100 hairs a day, then if that^ theory is true,
s/he would take 1000 days for all the hairs to go through the shedding process.
That works out to be a little under 3 years.
Now comes my feather-ruffling point:
For someone who loses 2 hairs a day, it would take 50,000 days for all the hairs to reach shedding = max length for each hair
That means terminal time (term) would be 136 years. LOL
OK, if that is the case, then considering that none of us have been around that long, then I don't thick shedding would have even started yet.
Yes, if you cut your hair today, you will still shed your quota at that TWA length. Why? Coz your hair follicles don't really care how long the hair is; they are just concerned w/ whether their lifetime (term) is over or not. So the reason hair will shed is because at the time of BCing, some follicles were at term time so those hairs that had been growing for years were just about to shed and it was going to happen regardless of what you did to the outside hairs.
So this is my belief: even when you THINK you only lose two hairs, that's a very optimistic view.
Shed hair comes out when
- you comb through your hair (usually with a comb whose teeth are so close together as to go between strands enough to not miss any),
- slide fingers from base to ends when finger combing like you're stroking your strands
- or brush your hair.
If you aren't doing this daily, just because you don't see hair fall doesn't mean it's not there hanging by a thread. If you were to gently tug on a hair that isn't about to shed, it would not come out unless you've got some type of follicular disease or hair loss. But if you were to start sliding your fingers from base to ends holding a very thin section of our hair--so thin that it's as if your hairs are in a line so that you are stroking every single one) and you did that on small sections all through your head, I bet you'd see more hair come out than you realized you were shedding.
*The reason I suggested that rate of shed (if accurate) might help with determining term (assume total hairs count is accurate too) is because when a new hair starts growing, it's because another was shed not too long ago. So let's assume today is the day Hair #1 starts its journey. It obviously will not be shed for a long time. One of the other 99,999 will be shed today, and tomorrow, and so on, until the day Hair #1 and any that were born the same day will celebrate their shed day. If every hair that was older has had its turn and now it's Hair #1's turn to fall out, logic tells me that Hair #1 has grown for as long as it could grow, which would give a good estimate of how long hairs on that head take to grow from birth to shedding, = terminal time.
