This drug produces less weight loss than the newer semaglutide and tirzepatide products, and its label does not report a quantified hair-loss frequency. Cohort studies of the class find the hair-loss signal concentrated in semaglutide and tirzepatide, not the older agents. 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.

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.

Does biotin help hair loss on Trulicity?
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.
