NO...and I don't mean hats will TOTALLY stop Androgenetic Alopecia but it does have some role in slowing things down. The reason that I think hats do have some role in both men and women is because UV exposure depletes NAD+.
UVB can also penetrate some clothing/hats too so protection isn't perfect. This also explains why blacks develop Androgenetic Alopecia at 1/4th the rate of whites.
Blacks also don't develop wrinkles not nearly as much either.
"Daily hat use (p = 0.050), higher body mass index (p = 0.012), and higher testosterone levels (p = 0.040) were associated with decreased temporal hair loss."
Same thing in female twins:
pubmed.ncbi.nlm.nih.gov
Factors associated with increased frontal hair loss included multiple marriages (p = 0.043); longer sleep duration (p = 0.011); higher severity of stress (p = 0.034); positive smoking history (p = 0.021); higher income (p = 0.023);
absence of hat use (p = 0.017);
and history of diabetes mellitus (p = 0.023), polycystic ovarian syndrome (p = 0.002), and hypertension (p = 0.001).

Ionizing- and ultraviolet-radiation cause cell damage or death by directly altering DNA and protein structures and by production of reactive oxygen species (ROS) and reactive carbonyl species (RCS). These processes disrupt cellular energy metabolism at multiple levels. The formation of DNA strand breaks activates signaling pathways that consume NAD, which can lead to the depletion of cellular ATP. Poly(ADP)-ribose polymerase (PARP-1...........
