Can you make a hairline more feminine?

I would be great to see the pictures as well. there are few options to improve the shape of hair line,  ranging from hair transplant to hair/scalp advancement. best wishes,

Thank you for your question about Forehead Lift. Pictures would be helpful.In general, yes, the shape of the hairline can be altered with a forehead lift or hairline lowering, hairline advancement.
To be sure, see two or more experienced,
board-certified Plastic Surgeons in your area for a complete evaluation to make
sure you are a good candidate and that it is safe for you to have surgery.
I hope this helps.

Your hairline shape and location, as well as the size and shape of your forehead can all most likely be reshaped by using pretrichial incision. It would be most useful if you would submit photographs to aid in the formulation of an opinion. Best wishes.

Without pictures it's really hard to give you an appropriate answer.  If it's just your hairline you want to alter you may consider hair transplants or advancing your hairline forward by moving your hairbearing scalp forward.  This may not correct the width but may be combined with hair transplants too.The advancement may not improve the width but can be combined with hair grafts.If you have heavy brows, causing a masculine appearance, the hair line advancement incision would work the best.  An endoscopic or coronal lift will increase your forehead size.

Great question.  Altering of the hairline can be done with a trichophytic brow lift incision, but not significantly so with endoscopic techniques.  A trichophytic incision could be used to decrease the relative size of the forehead, and also shape the anterior hairline, but this would require thick hair to hide the scar.  If there is thinning of the anterior hairline, hair transplantation may be needed.
