Thanks for posting your query on health care magic
Firstly we should find out the cause of excess facial hair for a female.ill advice you to visit an endocrinologist
and a gynecologist to rule out hormonal
imbalance and PCOS
The best way to remove excess facial hair is by Laser
since the Laser targets the pigment in the root of the hair follicles which gradually decreases the hair to almost negligible .Various choices are available with dermatologists and laser surgeons in form of Diode , Nd Yag or IPL in decreasing order of efficacy .You need to undergo the treatment in 6 to 8 sittings with every sitting around 4 to 6 weeks apart.
I hope i have answered to all your queries
If any further doubts feel free to post again
