advice on bleaching a scalp with scabs

so I have to dye and bleach my hair tomorrow before an event happens but my scalp, particularly my hairline, has a few scabs from zits. is it still fine to bleach my hair? cause i kind of need to... im primarily just gonna be bleaching my roots as a touch up. would it be fine if I like covered the scabs in Vaseline and avoided them??? theyre pretty small scabs...
