The Ozempic label lists alopecia only under postmarketing reports (Section 6.2), with no frequency and the standard note that a causal relationship cannot be established from such reports. It is not in the trial adverse-reaction table at all. The shedding some people notice on GLP-1 medicines is usually telogen effluvium, temporary shedding that follows rapid weight loss rather than damage to hair follicles. It typically starts two to four months after the fastest weight loss, and the American Academy of Dermatology puts recovery at six to nine months once the trigger settles.
What the Ozempic label says
The Ozempic label lists alopecia only under postmarketing reports (Section 6.2), with no frequency and the standard note that a causal relationship cannot be established from such reports. It is not in the trial adverse-reaction table at all.
Ozempic is a diabetes dose of semaglutide and produces far less weight loss than Wegovy, which is the likeliest reason its trials never surfaced a quantified hair-loss signal. Most striking "Ozempic hair loss" stories online are either off-label use for weight loss, Wegovy results, or compounded semaglutide.
Hair loss is listed as an adverse reaction, never as a boxed or Section 5 warning, for any drug in this class.
Why it happens, when it stops, why some people say it never grew back, what helps (and why biotin can interfere with lab tests), and when shedding points to something else are covered once for all GLP-1 medicines: GLP-1 hair loss and what helps with GLP-1 hair loss.
Common questions
Does Ozempic cause hair loss?
The Ozempic label lists alopecia only under postmarketing reports (Section 6.2), with no frequency and the standard note that a causal relationship cannot be established from such reports. It is not in the trial adverse-reaction table at all.
Does biotin help hair loss on Ozempic?
Evidence does not support biotin unless you are genuinely deficient, which is rare. The FDA also warns that biotin interferes with lab tests, including troponin, where it can produce a falsely low result and mask a heart attack. Test before supplementing.
