White spots in 3D view?

Hello, this is my first time using blender and after following a few tutorials I made this model. Originally the head wasn’t connected to the body and the piece of hair wasn’t either so I clicked “apply” on the mirror modifier and joined the pieced to the thing and now there’s white spots on it? I don’t want to have to retexture the whole thing…
When I joined the parts I marked the seams and unwrapped them and then i placed them on top of the existing textures???

Sorry if this is a simple problem!!! Thanks in advance if you can help me!
[EDIT] nevermind I fixed it!
