One Side Grows in Wavy, One Side Grows in Straight

I am black and my new growth comes in wavy and is sensitive in the middle top part of my head. Also my right side of my hair is wavy and thicker than my left side which is more straight and thick but not as thick as my other side.I wish my straight side would match the wavy side.What could I do to make this happen?

It is not clear what you are referencing here. When you talk about new growth, is that transplanted hair (which often comes in slightly wavier) or is it growth from Propecia (which may reflect different degrees of miniaturization)? Or is it just regular hair growth? Sorry, your question just isn’t clear enough.

For what it’s worth, hair that is miniaturized is often less wavy than the wave in the normal hair that may be present. I am assuming that you are a male and not talking about minoxidil growth (which is less predictable a drug).
