I went further down my friends list to expand the sample size, I'm skipping over people who have good hair or who are too old to be relevant:
6th guy, NW3, married an attractive white woman, however he's relatively high-status
7th guy, NW3, long-term relationship with a white woman
8th guy, NW6, went bald young, probably a virgin, also overweight, short, ethnic, and has bad social skills.
9th guy, hairline receding but has an effective combover for now, in a relationship with an attractive white woman
10th guy, NW6, went bald young, plausibly an incel
11th guy, NW3, he's seeing someone now but I don't know a lot about her, he also tries extremely hard.
12th guy, receding and thinning NW2.5, long-term relationship with a white woman\
13th guy, receding and thinning NW2.5, long-term relationship with a white woman\
14th guy, NW5, recently married an attractive white woman
15th guy, NW5, married an attractive and brilliant white woman a few years ago, their second baby is recently born.
So overall it's a mixed record. I listed ten additional names here and I'm a bit too tired to go on. The most attractive woman on my list is also with a bald guy. The most recent engagement I read about on FB was of a bald guy that I knew from the mining industry.
There's certainly a correlation in the real world, but it's not as ironclad as people such as the OP think. However, I suspect that it's almost certainly the case that matters more in the age range 18-23.
For comparison, the first five guys with pristine or near-pristine hairlines
1) Married an attractive white woman of high social status a few years ago.
2) In a long-term relationship with a passable white woman of high social status for nearly fifteen years.
3) Single the last time I asked. He has other problems to deal with.
4) Married, divorced, now is with another good girl.
5) my brother in law, I'm biased, so pass.
6) Married a white woman several years ago.
