If you are losing hair, it is most likely not the transplanted hair, but your native hair. At the age of 25, shock loss can be expected ,and to prevent this, you should have been put on the drug Finasteride, which usually stops this from happening. You can’t go back and reverse the hair you lost, but you might stop more hair loss from happening with this drug. Get a doctor involved like me, who is experienced in this field and will help you manage the problem. I often help people who have been treated overseas and don’t have a local doctor.
