When Branneisha Cooper first began taking GLP-1 injection Mounjaro in late 2022, she heard online that she could experience temporary hair thinning and prepared for the worst.
But it would take about a year before she began noticing her hair falling out in clumps. Cooper said it was especially shocking because she has always had thick hair.
“I was really hoping it wouldn’t happen,” Cooper, 29, told CNBC. “What my provider had told me is that since you’re on the medication that’s allowed you to lose weight at a faster rate, that’s what can cause hair loss.”
Desperate to counteract the side effect, Cooper said she began prioritizing protein in her diet, taking vitamins intended to help her hair and investing in haircare products meant to stimulate the scalp to foster growth.
She’s one of a growing number of GLP-1 users experiencing temporary hair loss from the drugs, creating a new market for hair treatment products amid the weight-loss drug craze.
