Does brushing wavy hair weaken its pattern long term?

About 4 years ago I gave up my usual heat styling and started CGM....I have mostly done that until the last few months I have been experimenting more with hair again.

My hair is dense wavy and dry. A couple days ago I experimented with velcro rollers which straightened out my hair. Tonight I brushed the hell out it with a hogs hair brush....and damn that hair is SHINY and straight.

I feel a bit uncomfortable/not myself in straight hair but it looks so healthy.

I am wondering if I started a routine of brushing out my dry hair once a week or so if that might improve my hair health and/or if it might wreck my wave pattern.

I want to improve health while keeping the pattern. I get that in the moment it will brush it out but will itake it worse long term?
