The hair/makeup person's job is to get the actors to look like their character so they are ready for the shoot. This includes wounds, blood, death, moles, and that glamorous hairstyle. Your actors may do their own hair/makeup, but if you need special effect (e.g. scrapes, slashes, decaying skin) a good makeup person would be very helpful. The hair/makeup person's line is: "What do you think? Good?"
