A pretty amazing testament to the power of concealers!
The grafts from your previous work do look rather pluggy and obvious. Frankly it isn't very good work. I don't like pointing out these things, but you know it already. A procedure using maximum available grafts, done right, to give you density across the balding area would go a long way to improving things and making you less reliant on concealers. You state that you want FUE, but you might want to consider a second FUT procedure to give you maximum grafts.
Are you against a second FUT?
