How do I fix this hair mesh?

Hi, so I tried meshing Maxis match hair from scratch for the first time using curves. I'm at the part where I have to UV map it but the tips of some of the strands aren't connected to the rest and it's a bit frustrating. I can't get it to look seamless no matter where I place them. I believe it's because I merged the vertices at the center to close the hole?


How do I connect those triangles to the squares? Or is there another way to fix this? Here is the .blend file.

TIA
