Hairs Per Square Inch Seems Lower on Sides and Top of My Head

22/male. My individual hairs don’t seem to be thinning all that much (meaning the diameter) except the overall thickness i.e. hairs per square inch has drastically lowered especially on the sides of and top of my head. Is this just a normal part of my body changing? In addition the spot of hair that juts out on the right side of my head (near the temple) is turning more into like peach fuzz but it is not quite like that on the left side. Are these the signs of MPB, I’m confused and worried. Thanks

It is impossible to answer your question without a formal physical exam and microscopic assessment of your scalp area by area. What you are describing does not particularly sound like a pattern consistent with MPB. The sides of the head are often less dense than the back of the head in non-balding people. There are other conditions such as diffuse alopecia areata (as an example) that may cause asymmetric hair loss in different parts of your scalp. You should see a qualified doctor who can perform a miniaturization study and density measurement to obtain a good diagnosis.
