See a dermatologist. Begin with a diagnosis. Not all hair loss is the same. Treatment depends on the diagnosis. You can probably be helped. Forget "natural". It has no meaning. Forget "homemade". It will get you nowhere. Forget "homeopathic". No homeopathic remedy is anything but placebo. Don't be a sucker for any of these con games.
Get seen. All normal men lose the hair on their temples at your age. If you're losing hair otherwise, it's probably telogen effluvium or alopecia areata and both should take you to a dermatologist -- one self-cures, the other is famously non-treatable and the remedy is to muscle up so that you'll look better than anybody else regardless. Hope you get this sorted out. Mr. Diesel (photo) isn't complaining.
