21, female & hairline is lacking - forehead lowering or hair transplant? (Photo)

Hi there, 21 year old female. No history of hair loss. I have always had a high hairline but after years and years of scraping it back into a high ponytail and extensions my hairline is lacking. I also shave my windows peak. I think it's a really weird shape but now grows back stubbly & weak. Should I go do the hairline transplant route or forehead lowering? Thank you!
