Metals are a good conductor of electricity. It's already saturated with electricity so it cannot hold anymore. But the plastic comb insulates the static charge to put up.

Both plastic and metal comb will get charged when rubbed in the hair. However, since metal is a conductor, the charges will flow to earth through the body and it will lose its charge. If the metal comb has an insulating plastic handle it will retain its charge.
