How common is diffuse thinning rather than a receding hairline?

[jackm415]

I've heard some places that most people start with a receding hairline, but I'm not too sure about people who just generally diffuse thin all around rather than the traditional norwood scale. There seems to be a lot on here but is it relatively uncommon in general? For most people, would the first signs to watch for hairloss be at their hairline? I think i read somewhere on reddit that the vast majority of people losing their hair are losing it through the traditional Norwood pattern. I do realize people who are losing their hair through norwood pattern can also be thinning, but my question more is about people who don't have a receding hairline but lose their hair throughout their entire head at once.

Is there any demographic groups that seem to be affected by diffuse thinning more than a receding hairline?

It would be interesting to have more detailed info about this. Someone could check out pubmed via scihub if possible to see if there are any papers available on it.

I can only provide anecdotal evidence from what I've seen here, from athletes, movie stars and hair loss youtube channels. I don't think pure diffuse thinning is as common as recession+thinning, pure recession or thinning at the crown. The genes inherited from the parents are what heavily influences things, as is the case with most diseases. Many men of northern european ancestry seem to recede up to the NW3-4 range and then start thinning out at the front, midscalp and/or crown if left untreated from what I've seen.

Men of Mediterranean ancestry on the other hand can follow that pattern too or have pure recession up to the NW3A-4A range, when they usually start thinning in a NW5A pattern if left untreated, again, if they have the genes for it. It seems to be more common in this case for hair loss to slow down or stop then, at NW5A-NW6.

People in Latin America are dominantly diffuse thinners.

Hair fibers are the best solutions to this. I mean women put on make up everyday, especially at work. What's the deal with putting hair fibers for just 20 seconds in your day.
