How can I faux hawk my hair so it won't split down the center into horns?

I have naturally very curly thin hair and have been straightening it for a few years now. Since I don't want to cause my hair to curl when I'm styling, I only use pomades or pastes because hairsprays and gels contain to much water for my thin hair. I try to rock a faux hawk but the spikes in the front splits down the center of my scalp and open and won't stay together as a faux hawk. It ends up looking like horns. Is there anything to do to keep it up and closed? Please help.
