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.

Taking the question as asked, rather than the general version of it. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.

Happy to go further on any of that.

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