What Norwood am I? Is it better to let hair shed further and start finasteride? (Photo)

Looking at the pictures I would say you are a Norwood V or VI. It seems you have adequate donor zone to restore the front and mid scalp areas with transplants. It will likely take at least 2 sessions of transplants, and I would recommend you do the FUT or strip procedures, to move more hair without compromising your donor area. You can also combine FUT and FUE on the same procedure to maximize hair removal safely. Finally, the use of finasteride and minoxidil is important so that your hair loss does not progress and becomes larger, which will increase the area that needs to be transplanted.

Hello I'm Dr. Wipawan Vathananai, a co-worker of Dr. Kulakarn Amonpattana, from BHI Clinic, Bangkok, Thailand. You have AGA V-VI since the bald area is very large. I highly recommend you to either start finasteride or dutasteride as soon as possible to preserve your donor hair. There is no need to wait.

Based on your description and Photos of seeking frontal and high mature hairline coverage, and without a visual reference, you might fall within the Norwood scale between II and III. It's important to consult firstly for an accurate assessment.
