What are other alternatives to wrapping hair at night?

I wrap my hair at night but I've noticed that my edges are starting to get thinner. I moisturize my hair with dr. Miracle's oil sheen spray and the temple and nape balm. I have a satin bonnet but my hair isnt as silky when i use that. I use the wrap cap that goes around the edges but my hair is so think my hair pops out at the center. I haen't used a satin pillowcase but I'm sure my hair would be wild in the morning. What can i do instead of wraps that will keep it straght and protected. I'm trying to repair the damage.
