Mature Hairline Measurements

I have been reading about the mature hairline in this blog and you seem to state different measurements in each blog. The temples suppose to be up to 1.5inches receded but the frontal hairline is anywhere from 1-3cm on this blog. Isn’t 3cm too much? The reason I ask it seems that where my hairline is heading although it’s only 1cm up but I can see it’s thinning out to that length.

I agree that 3cm elevation for the mature hairline from the highest crease of the furrowed brow is high for the mid-line. I use my finger and generally see about one width of my index finger… and I don’t have fat hands. My index finger is 2/3rd of an inch wide.

There is no hard rule on measuring the mature hairline and each person is different, so this is a loose measurement.
