How fast does hamster hair grow?

Hamsters' fur typically grows about 0.5 to 1 inch per month, but this can vary depending on the breed and individual hamster. Syrian hamsters, for example, typically have longer fur than dwarf hamsters. The fur on a hamster's body will also grow faster than the fur on its head and feet. Generally speaking, a hamster's fur will need to be trimmed every few months to keep it from getting too long and matted.
