This is telogen effluvium and the trigger is the rate of weight loss rather than the molecule.

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. Filing an objection on the n=1 problem. Personal experience is genuine evidence about one person and very weak evidence about anybody else, and this thread keeps promoting the first into the second.

Short answer first, then the reasoning. Worth answering the question that was asked rather than the one behind it. The narrow version usually has an answer; the broad version usually does not, and answering the broad one is how a thread stops being useful.

If somebody has the primary source to hand I would rather cite it than paraphrase it.

This is my experience too, for whatever a second data point is worth. The detail I would add is minor and it is already implied above.
