You can see in these two photos that this man’s right side has already undergone changes in maturation, while his left side (see arrow) shows the left side thinning, matching the other side once these miniaturized hairs have fallen out. These hairs may respond to finasteride in men under 25, less likely as the age increases in the frontal corners. The asymmetry is not unusual in my experience as sometimes one side recedes faster than the other side. Note that the hairs on his left side that are miniaturizing and falling out (arrow) hugging the highest crease of his furrowed brow. That is how I know this is a transition for a mature hairline; however, to be sure, I would want to look at the hairs 2-3 inches behind this leading edge to see if the hairs are miniaturizing. If they are not, then this could be a maturing hairline in a person with a strong, low central forelock. This is important to know because if this man assumes it is a balding process and starts on drugs like finasteride, he may be committing a lifetime of treatment unnecessarily. As a hair restoration specialist, my job is to make a proper diagnosis and help not only the balding men, but the men who think they are balding and are not. The value I bring is to differentiate between the two.
