Is Hair Diameter Consistent Throughout The Entire Scalp?

[NormanNorwood]

So I read that the diameter of hair can vary from individual to individual. However what I couldn't find was if hair diameter is universally the same across your scalp or if hair at your forelock for example is thicker than hair on the sides or crown?

Also the hair on the back of my head (where Norwood 7's keep their hair) is coming out minituarised in the shower? Are these just naturally really thin in diameter hairs? Seems odd to me

Initially all healthy scalp hairs have the same diameter

The why are all the ones right at the back of my head minituarised also?

I've read somewhere that people unaffected by male pattern baldness have around 10% of hair those are smaller in diameter than the rest. If you're having more than 10% then it could indicate male pattern baldness.

Not sure if this is reliable way to tell.

It is not normal, maybe you must make a trichogram
