How much hair people grow varies tremendously between one person and another, regardless of skin color. Nutritional and hormone factors play little or no role, either in causing hair growth or promoting its alleviation.
Laser is the best approach, now that the technology is proved, safe, and fast enough to be affordable.
Many laser systems are available, and although there are differences, no one is head and shoulders above the rest.
The criteria I would look for are experience and price, which vary widely. Ask your friends, look around, and get a few consultations. And don't tan, since the more color your skin has, the less likely any laser is to be usable and effective.
Five years ago, you would have had no options. Now you have several. I suggest you at least look into them.
Best.
