I am the individual who this thread is about, and I would be more than happy to answer your question. Thank you for the kind words as well.
As Dr. Umar mentioned, I kept my hair very long both on the back, as well as the sides to conceal my situation. Moreover, regarding the hair before my surgery with Dr. Umar, I used to literally inundate my head with toppik, and a few other concealers before I went to work, or out of the house for that matter. It is such a great and rewarding feeling not having to use concealers any longer.
I have also created a blog documenting my hair loss experience since the age of 18, and there are some more updated photos within it.
I hope my experience can help others in the same situation.
All the best.
