Is there any truth that a peptide called TB-500 also know as Thymosin beta4 help with thinning hair?
Not that I’m aware of. There was a mouse and rat study published years ago that got companies excited to start marketing Thymosin beta-4 as the next great “cure”, but such studies are a long way away from human proof.
I haven’t seen anything about it in recent years, which leads me to believe it went nowhere. If anyone has more current info, please feel free to send it in!
