The first page on this thread has a few and even that small sample shows posture and neck alignment correlation, I see this everyday without thinking I see a bald person 90 percent chance they have poor neck alignment compared to those with good hair, harder to tell with galea shape of people with good hair but bald people also generally have what you've described above in terms of shape. Absolutely amazes me how so many people still dismiss this. Only answer is to fix the route cause which isn't easy, or take strong meds and hope you remove enough DHT to make a difference.
