Here are additional hairdos from the 60s. These were passed down from other time periods, but I think they were still equally cute in the 1960s. These will also look great on Melody with her shoulder length hair.
Plus if you have a doll with straight hair and tendrils at the sided like Marie Grace and Elizabeth then you can use their hairdos as examples too. These styles were extremely popular in the 60s with hair accessories.
