(Concern) If I correct my hairline, will it also correct my hair part?

There is a chimney in front, and the cow's head looks like a fringe, with the bangs lying flat. Additionally, since it's a three-person forehead, even when the bangs are pulled down, they don't fall well, and as I get older, my hair becomes thinner, making my forehead look wider and giving an empty feeling.

So, when I do my makeup, I tend to use shading to make the sides of my hair a bit darker and also cover the front hair area a little.

If I correct my hairline, to what extent can I also improve my hair flow? Since hair flow correction cuts or hair perms at a beauty salon are temporary and need to be done periodically, I wonder if it might be better to opt for hairline transplantation instead.

They say that after a hair transplant, the hair initially grows in a curly manner, so I'm even more worried because I already have wavy hair.
