I Am a 21 Year Old Female and I Want a Rounded Lower Hairline

I have a very square hairline along with a large forehead. I have heard that a forehead reduction can lower the hairline but that hair transplants would be needed as well to round the hairline out. Is it possible to round out the hairline with just a forehead reduction (by taking the forehead down/in more on the sides)?

This can only be created with a hair transplant.  A hairline reduction surgery can lower it but not round it. I wrote a chapter in a bood on this subject here: https://newhair.com/wp-content/uploads/2018/11/phenotype-article-published.pdf
