Yes Helen, there are specific areas on both men and women that are constantly in flux. Actually every area in and on the body is changing, it’s just that we don’t easily recognize it. It’s called “aging.”
When men come to me with ear hair, they are always warned in simple terms: your ears are never going to stop producing hairs.
Once a man gets to a certain age the “billions” of vellus ear hairs begin to slowly get larger. These hairs accumulate over his entire lifetime. The only success I can have is removing the hairs we see at the moment. But this will be an on-going situation for all the years to follow.
Of course, knowing this does not deter the guy from saying, “ALL my ear hairs have grown BACK! Is this ever going to work? What are you doing wrong?” (I can’t write what I usually say to the guy: but there are a lot of “Fs” and Sses" in the statement. With humor, of course.)
Similarly, I usually don’t recommend removing leg hair from men, because it naturally thins out … and pretty quickly too as testosterone levels decrease. In a man’s 40s, he usually has less than half of the original leg hair (thickness and hair count). Leg hair steadily declines until you get those hideous “old man hairless legs!” I have them now and it’s disgusting!
I wonder if I can get a toupee for my legs?
