If you are experiencing significant hair loss and facing the most common problem i.e. androgenetic alopecia that makes people completely bald, unfortunately, there is nothing that can perfectly do a job for you. The best thing you can do is to take a hair transplant treatment as soon as possible.
With all the excitement that surrounds you, finally taking the important step to there are a many things to consider before this surgery.

Slow down a bit and make sure you’re clear about what to expect during and after this procedure.

Choose a good clinic What you can do is visit your nearest doctor or even you can take help of world famous specialist like Dr. Cole at http://www.forhair.com/Articles/Treating_donor_scars_with_follicular_hair_transplant-CIT.htm so that they can monitor this for you as well.

Closely follow the instructions you’ve been given to prepare for the pre-operative phase of your transplant, but also pay special attention to the written instructions on post-operative care. Both are essential to the overall success of the transplant.
