Wavy hair after shower

For as long I can remember my hair was straight.Last couple of months after shower I notice slight pattern of wavy hair.Nothing crazy but it’s there.

What are drug store products you would recommend to style.

*I have some type of alopecia and I’m on meds and doc told me changing pattern could be due to new hair growth and also I’m mom* if that matters

This picture was this morning after shower and after scrunching water out of it.
