Is ir just me or is dr rahal very underrated

i have been researching transplants for a while now and i have narrrowed it down to 2 doctors, my hairline has thinned out a bit and i have some mild temple recession , im looking to thicken my hairline back up and to fill in my temple., alot of doctors seem to get mentioned but dr rahal,s name dosnt seem to crop up as much as other doctors , is there a reason for this, his results look fantastic the 2 doctors i have narrowed it down too are dr rahal and dr armani, i am presently leaning towards dr rahal because his results to me seem to be very consistant and he seems very capable of dense packing a hairline , and his rates are very good, love to hear some views and recommendations thanks.
