There are most likely a number of issues happening right here.
Once more, weight reduction is linked to hair loss, particularly when it’s quick or dramatic, says Susan Massick, MD, a board-certified dermatologist at The Ohio State College Wexner Medical Middle. GLP-1s are recognized for serving to folks to shed extra pounds rapidly, which may clarify why some sufferers on tirzepatide and semaglutide have been confronted with hair loss.
However tirzepatide and semaglutide work somewhat in a different way within the physique, which may clarify the hole in what number of sufferers ended up with hair loss on the medicines. Semaglutide acts on one receptor within the physique, referred to as glucagon-like peptide-1 (or GLP-1), whereas tirzepatide works on GLP-1 and one other receptor referred to as glucose-dependent insulinotropic polypeptide (GIP), Dr. Zeichner factors out.
“For the reason that tirzepatide impacts a couple of receptor, it might have a higher influence on the physique than simply weight reduction,” he says. “GIP receptors have been recognized within the hair follicles and, because the drug binds to those receptors, it might impact the microenvironment surrounding the hair follicles, impacting their exercise.” Cue the hair loss—in some folks.
Girls on tirzepatide who skilled hair loss have been additionally extra more likely to have irregular intervals, hypothyroidism (an under-active thyroid), and polycystic ovary syndrome (PCOS) than those that didn’t have hair loss. “These are associations, not proof that any of those circumstances trigger medication-associated hair loss, however they counsel that underlying hormonal or autoimmune susceptibility might matter alongside weight reduction for girls utilizing tirzepatide,” Soundararajan says.
Dr. Massick additionally stresses that the info doesn’t inform the entire story. “This [new] examine doesn’t actually seize different confounding elements resembling life-style, dietary consumption, and different underlying medical circumstances,” she says. Which means, there could possibly be one thing happening with people who find themselves extra possible to make use of tirzepatide that raises the danger of hair loss—and it might don’t have anything to do with the medicine itself.
