Excessive hair on face. Results?

I have excessive dark hair on my chin and uper lip also on chicks near ears. I have taken 10 laser hair removal treatment sitting from well known dermatology clinic in Ahmedabad. During the treatment i have seen reduction of my hair growth. But as soon as i stop the treatment, hair growth started coming after 2 months. Now its almost same before the treatment. I had done blood test in laboratory which doctor prescribed me for pcod/pcos, but did not diagnose with that. ( Also,I have regular menses with no difficulties) But my Testosterone level was- 51ng/dL (Normal- 9-55ng/dL) , which is on border line. And prolectine level was 33 ng/mL (normal- less than 30ng/mL) which is higher than normal level. Rest all female hormones and other tests were normal. Please adress me now how to deal with this problem?  If i go for laser hair reduction treatment agin is it possible to have satisfactory results?
