I am 27 years old. Can I transplant what you see here and how many grafts?

What I need is a frontal picture with your hair pulled back and your eyebrows lifted high so that your forehead creases. That shows me the anatomic points that allows me to determine the proper place of the hairline.  Then your question can be answered.  This picture suggests hair loss in the front as well as the large crown loss shown in the picture you supplied. You should send photos of the frontal area as well so that we don’t give you half an answer to your question.
