i recently bought a hair concealor called megathik, its like toppik, and since i live where toppik isnt available locally i tried it, and to my suprise its magic! ok it has its limitations with water and sweat etc etc, but its definitely given my confidence back, it covers up nicely my hair transplant scars and my family and friends dont even know.
you do need hair, and it needs to be longer to be more effective in the way it looks.
previously i dreaded working, going out, seeing anyone, i was depressed and very mentally scarred from my hair loss. now with hair transplant sessions and this concealor stuff i feel like im getting my life back.
