I too have experienced shedding but not really sure if it makes a noticeable difference in the volume of my hair when it happens. What I notice is that there will be times when I notice more hair in my comb/brush. Ofcourse I panic for awhile but it seems to stop after about a month or so. Not really sure if there has been a pattern at all like time of year, periods of stress, etc. Likely there is and I haven't pieced it together.
I have made this experience, too. After 1,5 years i had a bad shedding and it depends on your nw pattern if it will be noticeable only for you or others, too. I think the transplanted hairs will change their growth circles often until a few years. Other reasons are possible, too.
I am sure I went through a phase of shedding around April of this year.. exactly one year post op from my Feller repair.
There seemed to be far more hairs on the pillow and in the bath than usual. I was convinced my hair was thinner... but to be honest I dont know if this was just paranoia ??
The worst part was that I had so many things change at the same time as my shed started..
1) New prescription of Proscar 2) Drastic change of diet 3) Change of shampoo from my regular one 4) 24/7 working 5) Had just changed my brand of hair wax... yep I even thought this may have been a reason !!!
Looking back I remembered that I had always thought my balding sort of sped up as the warmer weather came along... though I am not sure if this was due to the brighter day light.. etc etc..
What ever... shedding does seem to be a curse now and again...
I think mine lasted for about 2 months... all seems ok now... I HOPE !!
