Hi S.-
Try to think in terms of a comparison to how much hair you had before your pregnancy. As you know, we hang on to hair while pregnant, and then the "normal" shedding that occurs postpartum is really a release of the extra that we didn't release while we were pregnant. You should end at a place that resembles where you started before pregnancy. If you're convinced you're losing more than that, then as a doctor, the first thing that comes to mind (as has been mentioned already) are thyroid levels. But what's important in any patient is the totality of symptoms, and what that implies about what is systemically awry, rather than getting stuck on one particular symptom and manipulating (or suppressing) it. Other symptoms of thyroid problems are constipation (which to me means less than once/day, or it's difficult to pass), dry skin, "brain fog", fatigue (these last 2 are hard to tease out from "regular" postpartum though! which is where a blood test comes in handy), weight gain; there are some others but those are the biggies.
It's sad that someone else had the experience with their doc that led them to say "prepate to be patronized." Nobody should put up with that kind of treatment from their doc! Get another one, I say. Try a naturopath if you haven't been to one before. Certainly we naturopaths are individuals, and much is about connecting with the individual person you've found, so there's no guarantee. But on average I see that naturopaths are more interested in and willing to take the time to educate patients, so you shouldn't walk away feeling patronized. Naturopaths are also going to look at you more systemically, and not only be interested in the thyroid - how about the other glands that interact extensively (like the adrenals - which are just about always fatigued in a postpartum mom - and the ovaries). I'd be interested in what those are up to, as well as the rest of the physical and emotional picture.

p.s., Thanks to the person who explained why us wavy/curly-haired folks lose so much hair in the shower. I never thought about that it's just getting stuck in the rest of the hair during the day, and releasing when I comb the conditioner through in the shower. Makes so much sense!
