Your losing hair in the front all the way back to the crown. Norwood 5A+
A HT for you would restore your hair for about "5 years" give or take, and depending if the meds work, and your hair loss slows down.
As you age, and (if the meds don't work) your hairloss continues, you would need another HT, to continue with what you think you need.
If you got a HT now, you would LOVE the results, because of the instant gratification and mostly you have lots of native hair. But as you age, your hair line is going to pull back, and you will need another one. They will become less effective, (due to your increase hairloss)
Believe ir or not, I think your hair is still way to good to warrant a HT. Don't use the wet shower bright sunlight pic, but the other to judge. You can use concealers, different hair style with a good barber for the next several years.
You also need to see if you like the shave look. You absolutely need to try it out, it will solve SOOOOOOOOOO much if you have the courage to shave it down.
Hairloss can be a brtual boy to man process. Try the meds, the concealers, try shaving it down..
hold off on a HT just yet.
