Talk to General Physician on Hairline Rescession

Aoa. I've had partial hair loss at my hairline area. It went back once but it has stopped there. I have full hair all around my head except a little portion of the hairline .Mature hairline doesn't seem to be the case here. I've tried many treatments (aloe vera gel, onion juice) without any strong results. I've have been worried sick about this for more than half a year.My parents have very strong hair and i think it is regrowable InshAllah. Any advice and treatment suggestions will be highly appreciated. Regards.
