This is the version of the explanation I wish somebody had given me, written down before I forget what confused me. It is about hair shedding, and it is deliberately narrow — everything I am not confident about is marked as such.
What is actually established
This is telogen effluvium and the trigger is the rate of weight loss rather than the molecule. Rapid loss pushes a large fraction of follicles into the resting phase simultaneously; they shed together two to four months later, which is why the shedding starts long after the loss did and why people misattribute the timing. It is self-limiting, and regrowth follows once the rate slows — the follicles are not damaged.
The condition it depends on
Worth adding that protein and iron adequacy affect the severity even though they do not cause it. Slow the rate, hit protein, check ferritin.
The practical version
The timeline that reassures people: trigger, then two to four months of nothing, then shedding for roughly three months, then regrowth. Diffuse thinning is expected; patches are a different diagnosis.
What I am not sure about
What I actually want to know is whether the shedding is the drug or the rate of loss, and when it stops. Numbers rather than impressions, if you have them.

Hair loss update related to hair shedding: I experienced noticeable shedding starting around month 5. My dermatologist confirmed it's telogen effluvium — a stress response to rapid weight loss, NOT the medication directly.
What's helping:
- Biotin 5000mcg daily
- Adequate protein (130g+/day)
- Iron and ferritin levels checked and supplemented
- Collagen peptides 20g daily
- Minoxidil 5% topical (prescribed)
The shedding slowed after 2 months and my hair is now growing back. Temporary but definitely stressful.

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. This treats a plausible mechanism as a demonstrated one. Plausible is where you start looking, not where you stop.
If somebody has the primary source to hand I would rather cite it than paraphrase it.

Happy to go further on any of that.

Same experience, arrived at from the opposite direction. Posting only so the count is not one.
