Does hair length increase hair loss when you have alopecia?

Hello,

I don’t know much about how alopecia works or anything but I know that I have it. It wasn’t noticeable until I let me hair grow out to my shoulders. I had relatively short hair for the majority of my live and wanted to let it grow however when I did I began to get bald spots due to the alopecia. Does it have anything to do with the length of my hair? If I could it would it prevent more bald spots from appearing?
