Greetings and welcome to justanswer,
The drug cozaar contains the losartan and may cause alopecia as the side effect on long term use.
You may try the other antihypertensive drug like amlodipine, nifidipine, atenolol which do not have any known side effect of alopecia causing hair loss.
Here is the link for more information
side effect of amlodipine

Let me know if you have any doubt.
Thank you!
