No Results Obtained After 5 Sittings of Diode Laser Plus 6 Sittings of Yag Laser, What to Do?

I have already taken 11sittings for facial hair removal but hair growth comes again with in 2months of the treatment. I am having dark toned skin. I am feeling increase in hair but texture of hair has changed to finer side. I am 20years old female of Asian Origen. I have already consulted with endocrinologist and have got all possible blood tests done. All the reports are normal. Pelvic ultrasound is also normal. Should I keep on getting laser done after every 3 months
