GLP-1 drugs may cause hair shedding in some users
A survey found 20% of GLP-1 users experienced hair shedding, but high-quality controlled trials haven't confirmed how often this occurs.
Why it matters: Millions use these medications, so understanding potential side effects helps people make informed treatment decisions.
Keep in mind: This relies on one survey without controlled trial data, so the true frequency of hair loss remains unclear.
