Actually Homeopathy will work fine. Probably the doctor might not have got the symptoms right from you or the doctor itself might be half baked. Hence try some other good Homeopath instead of believing some unknown oils.
First of all try to understand one thing. The hair loss cannot be treated with external oils alone. Because lack of some hormones like Estrogen are responsible for hair loss. Hence you should take internal medicine as well as external oil/drops for controlling hair loss.
Hence try to consult some good Homeopath or else try some good Acupuncturist. In Acupuncture, they\'ll treat to level all the hormones which will effect in hair growth. Along with that u can use all these oils.
