What is the best procedure for me to get a more symmetrical hairline? (photos)

If you want a symmetric hair line, a hair transplant surgery may be one option. It is best to see a doctor for an examination / consultation.

Redesigning the hairline with hair transplant grafts would be the easiest procedure.  An experienced hair transplant surgeon can help you with having any hairline you desire.

I highly recommend the manual FUE method in order to achieve the best potential result. It is possible to create a hairline that is more suitable for your facial traits and to narrow the width of your forehead. 

Yes, hair grafting/ transplant be an option or forehead reduction and correcting  asymmetry on your frontal hair line/forelock. I advice you have a FUE; you would get the desired hairline in just one sesssion of dense packing hair transplant

It appears that you are female and young. In my opinion, hair transplant is the better choice than forehead reduction surgery but they are both options.  I have seen many women experience thinning later on (after menopause) that allows the forehead scars to be very visible. Transplanted hair will always look natural and would blend in better with thinning hair if that should happen later in life. Most women opt for strip surgery (FUT) rather than FUE because it requires less shaving of the donor area.

Hair transplant is a great option for you. I prefer ARTAS FUE so that you don't have a large scar from the donor area on the back of your head. The grafts are then place asymmetrically to give a more symmetric hairline.  Forehead reduction will leave you with a scar anterior to your hairline that you may then need to graft to disguise -- so just do the hair.  Good luck!

It is not clear from the photos if you are a male or female. Hair transplants work well to balance hairlines for either sex

Hair transplants can be done to improve symmetry or you could have a forehead reduction which would improve facial proportions and improve symmetry at the same time. Consider the Irregular Trichophytic Hairline Incision Technique that we described many years ago. Consult with a surgeon experienced in both procedures.

Haiir transplantation,in perhaps two sessions, could contour your hairline quite accurately. If you have future hair loss, more work can be done
