Bluecyclone, been reading your accounts. I think our situations seem relatively similar. I'm 40, have relatively longish hair. Although I started losing my hair when I was 18, I seem to have been shedding like crazy for the last year. I was on Finasteride for about 13 years, but switched to Dutasteride in March/April this year because I'd noticed increased shedding and figured Finasteride had lost its efficacy. I don't know if your body's ability to fight hairloss deteriorates as you get older, or if there's any evidence that these drugs stop working over time??
Anyway, I'd been catching around 100 - 150 hairs per shower (that doesn't include all the extra ones that I miss of course, so figure could be double!). I think that's possibly slowed to around 40 - 80 hairs at present that I catch, but I do seem to be shedding hairs all over the place. Always some hanging off. ALso, I am pretty certain that the shedding increased with the Dutasteride. There was a photo I posted on another thread right after I'd had a shower, and my God, it was a crazy ball of hair I'd lost.
I haven't noticed massive changes on my head, except for a little further thinning at the crown and a wider part, especially if the hair's wet and I part it. It's very, very difficult to tell with my hair because my hair is SO fine naturally. Where it seems to be thinning on my head, my gf tells me it's no different to how my hair is all over, even in the non-thinning parts.
Here's a photo I took of my hair a couple of months ago. My hair is wet and has a deliberate part. I guess the biggest difference between our situations is that I began losing my hair when I was 18 (so 22 years ago now). I have had 3 hair transplants to bulk the hairline though.
