Read the primary source rather than the write-up and the two do not agree, so here is what is actually in it.

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.

Where I think it is weakest: the subgroup findings are the part I trust least — with enough subgroups something is always significant, and these were not all pre-registered.

The narrow version of the question is whether the shedding is the drug or the rate of loss, and when it stops. Happy to be told the question itself is wrong.

Note on sourcing:
Figures above are from the primary publication rather than the press summary. If a number here disagrees with one you have, post yours and we will work out which of us is reading a secondary source.

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.

This is where I part company with the consensus forming above. This treats a plausible mechanism as a demonstrated one. Plausible is where you start looking, not where you stop.

Answering the narrow version, because the broad one does not have a single answer. It helps to ask what evidence would change your mind before you look at any. If nothing would, the discussion is not about evidence, and it is better to say so early than to spend nine posts discovering it.

This matches mine closely enough to be worth saying so out loud.
