Thanks for the query.
Description of your hair fall is suggestive of "Male pattern baldness" also know as "Androgenetic Alopecia". This is due to combination of genetics and hormones (
Testosterone) influence on the hair follicles. In addition, lack of hair care and nutritional deficiencies may hasten the problem.
There are many treatment options available which include topical (lotions/ spray) like Minoxidil which improves the circulation to hair follicles, and oral medications like Finasteride which block the effect of hormones on hair follicles. The definitive treatment, in suitable patient, is Hair transplantation after the above mentioned treatment (topical & oral) has been used for at least 3-6 months.
Next Steps
I would strongly suggest you to consult a Dermatologist for a proper assessment and customised treatment plan.
