I need to make an Ariel Princess cake and I'm not a very good sculptress so I bought a plastic doll figurine and I cut off her hair (it was blonde) I was trying to attach fondant hair to her head but I haven't been very sucessful. Any suggestions???

I would use piping gel. That stuff works really good....I use it for a number of things. Or maybe even some royal icing

Cut a small thin circle out of fondant and attach it to the doll like a scalp. Then you've got something for the hair to stick to. If you have Tylose powder, you can make a sturdy glue by dissolving some in water. In a pinch, I've also melted a little ball of fondant in a bit of water to make the glue.

Thanks for your help! I used both ideas and worked well together
