Can you recommend a doctor in LA?

Probably within the southbay area.

Im 35 years old, male , i recently see signs of shedding.
The crown and front area is starting to thin and i would like to save my hair before it get worse.
i am living a healthy life, workout 3x a week, takes vitamins and protein shakes and eat healthy food.
I use nizoral (since i have occasional dandruffs), nioxin and tea tree oil shampoo.
I would like to take propecia but i am afraid with all those side effects that i am reading.
I would like to consult to a really (recommeded) good doctor to save the hair i have now.

Thank you in advance.
