Good to see your progress! It looks like you've made some progress. I have been contemplating a laser comb recently. I didn't realize that there was actually research to demonstrate its efficacy.
I agree with most others here. Take finasteride as soon as you can. It is very likely going to work (more than 80% chance) and it will probably help keep the hair you already have. I feel your hair loss is minimal so far; try to keep it that way!
