What can I do about my uneven hairline?

Since women are traditionally less ideal candidates for full hair transplant surgery, given their diffuse hair loss patterns, I often recommend platelet-rich plasma therapy, with the addition of ACell, which contains growth factors that stimulate and enhance hair follicle function.
With that said, an experienced hair transplant specialist can fill in and round out your hairline with minimal incision and downtime. For safety and efficiency, I find it makes better sense to opt for hair grafting (FUE) as opposed to surgical hairline lowering.
 A note of warning: not all hair transplant procedures are equally effective or safe. Make sure you research and find a well-qualified and experienced board-certified surgeon who specializes in hair transplantation. The difference between an experienced hair restoration specialist and a non-specialist can often mean the difference between success and failure.

Due to the fact you keep such long hair and don’t want to shave your head FUT will work very well for you. Make sure you meet with a hair specialist that will go over your options and draw a natural looking hairline for you.

Greetings,I would recommend that you consider a small hair transplant session in this area.  The risk of permanent hair loss or visibility of the donor site in the back is very low, and the hair transplant would avoid any scars in the area of your hairline. Good luck!
