cheap hard brush messed up my waves

wassup everybody, i'm new to the site but not necessarily new to the wave game. But my problem is that i went to sally's and they didn't have a diane or annie hard brush so instead i bought this brush called "brush n strokes" and i used it when i got home. I'm on my 5th week of wolfin and my hair was layed down pretty good from brushing, but this cheap brush completely lifted all of my hair up, & made it look like i just used a pick. My question is that can a very hard brush permanently mess up your waves and should i stop using it or am I just worried for nothin.

 the saying goes you get what you pay for ...get you a Diane

If it ain't Diane then it doesn't exist.
