I can be wrong at times but I rarely am with this since I studied it a lot after I had recession once upon a time. Plus I had a surgical one made to restore mine and he calculated everything. My corners go up 5mm in relationship to the centre, it's a Norwood 1 to 1.5 max according to them and others. What I've drawn here would be his Norwood 2. The vertical lines show what would be Norwood 3 so he is beyond a 2 and it's balding. Between a 2 and a 2.5 if we were being pedantic.

Look here, how the corners go up a little too much and the tell tale sign it's beyond the Norwood 2 non balding hairline and active balding is the erosion of his temple points.

This is a good one because his forehead is creased. Notice how the widow's peak is still touching as it's a remnant of childhood and didn't mature. The corners should only be up to an 1 inch or maximum 1.5 inches higher from the juvenile point but it's exceeded that especially his right side. The hairline is also asymmetrical, natural hairlines have small variation but not that much, again balding. Right side has taken more of a hit - too typical in Androgenetic Alopecia.

He has a good head of hair otherwise and the rest is thick (I had this). Just getting on meds and having a transplant a few years later for the front if it bothers him is all he needs. He needs to stabilise and get to 23 as a minimum before considering this. Apart from BDD guys who overestimate their hair loss (which may be zero) most of us don't pick up early hair loss and the delay can be frustrating when more balding happens.
This is a classical strong Norwood 2 once posted on this forum.
