Six weeks of shedding, no bald patches, and a GP who told me to come back in three months.

Hair loss update related to hair shedding: I experienced noticeable shedding starting around month 4. 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.

That is right, and it stops being right at the edges. The general case is well behaved; the interesting cases in this thread are all at the boundary where the general case breaks.

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

Clinical perspective, offered as context rather than as advice. 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.
