Size of Miniaturized Hairs

Hi there,
I have read your explanation of hair miniaturization, and have a question. I am a 30 year old female and I am experiencing hair loss. My hair loss seems to be diffused, with areas that are worse which are my hairline, as well as the crown (alot of my scalp can be seen at the crown). I have been obsessively reading about it on the internet and have found it helpful but confusing information. Anyways, back to the question. I have alot of miniaturization hairs throughout my hair. By alot I mean alot, they stick up everywhere. Do these hairs every stay at a certain size, or do they always end up being very small and thin? Some of mine are extremely thin, and others are thicker. Thanks in advance

This is a good and insightful question. The general belief is that miniaturized hairs are impacted by hormone and genetic influences. As some hair is impacted and others are not, I would think that the impacted hairs (the miniaturized hairs) remain impacted and thin, unless things change like hormone balance, or the effects of medications such as Rogaine/minoxidil. As no one has ever actually tracked a single hair in a follicular group when cycling occurs (anogen through catogen phases), one really can not tell the actual answer to this question other than make a good guess (like I am doing here).

Follicular units usually contain a number of hairs. Mature healthy hairs are called ‘Terminal Hairs’ while the small hairs in a follicular unit are called ‘Vellus Hairs’. Miniaturizated hairs are thought to be ‘sick’ terminal hairs, not vellus hairs. Does a terminal hair become a vellus hair or visa versa? I doubt that, but do not know for sure. Do the hairs in a follicular unit play musical chairs (opps hairs) and change their appearance over time in a single hair cycle? I can have fun with these types of questions, but that is my intellectual exercising of random thoughts that you stimulated have no particular value to help you with your question.
