Th anks for posting your query
First of all we have to acsertain if you have male pattern baldness
or any other disease on scalp.
This is important as you have been taking treatment for one year now.
Secondly, you may have to undergo blood tests like thyroid
profile, hemogram and serum ferritin levels
Thirdy, your family history must be known for any correlation.
hence I suggest that you can consult a good trichologist or dermatologist
at your place.
You need a long term treatment.
If not better you may have to undergo hair transplantation
.lease check all these with your doctor
Have a good day
