Is it normal for hair to thin towards the root in a single strand during the balding process? Looking at the photo below, can you tell if there any miniaturized hairs?
Let’s say the hair is on average 10 inches long and that you can easily tell towards the root it is a lot thinner than at the tip. You can also see there is a lot less pigmented towards the root.
You are very observant. The thinning hair closer to the root may be the effect of early miniaturization. This occurs at the most recent part of the hair that is growing. I believe if you observe this over time, more and more hairs will become miniaturized and reflect the genetic balding process that is taking place. Of the two hairs in the photo, the one on the right is miniaturized. It is thinner and has less pigment in it. I am fairly certain that it took longer to grow as well because miniaturized hairs grow slower and then either fall out or stop growing altogether.
