Is it possible to get waves without brushing?

I hate brushing cause it makes my scalp tender. I had waves a year ago and it seems my pattern has been so set that my hair still grows in it despite not having waves in a long time. Can I just rag up for an hour or two a day and get waves? If not, is it fine to brush for like just 10 minutes a day if that's enough for me to get 100 strokes per side? I just want to minimize or eliminate this part of the process if possible
