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.

I am going to disagree with the direction of travel here. The thread has converged on the tidiest answer rather than the best-supported one, and those are not the same thing.

This one has a reasonably settled answer, so here it is. The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either. Those three things can all be true at once, and most arguments here are two people holding different parts of that.

Same experience, arrived at from the opposite direction. The detail I would add is minor and it is already implied above.
