Is it normal to have grey hair at 24?
Unusual.Less common, but harmless
Yes, you can have gray hair at 24, and it’s often just down to genetics. It’s earlier than average, but usually harmless.
Gray hair shows up when hair follicles make less pigment, and your genes have a lot to say about when that happens. If close relatives went gray young, you may be following the family schedule—annoying, but not unusual enough to mean something is wrong.
A few gray hairs in your twenties are generally nothing to worry about. If the change is sudden or comes with other new symptoms, it’s reasonable to ask a healthcare professional about it.
