Hibiscus is believed to be effective for hair loss

Condition analysis:
If you have thinning in such a broad area, most likely your donor area is also thin and you would not be a good candidate for surgery.

An examination can determine this and also determine if there is some other cause of your hair loss other than genetics.

Instructions:
Hibiscus: Also called shoe flower, hibiscus nourishes hair, prevents premature greying, treats dandruff and also controls hair fall. 

Steps:
Crush a few flowers and mix sesame or coconut oil to make a paste.
Apply on the scalp and hair and leave it on for a few hours.
Rinse off with cold water using a mild shampoo.
