I had diffuse thinning for 2 years, and now my hair is suddenly regrowing, will miniaturized hairs on right side of my hairline get thicker?
Miniaturization in genetic hair loss reflects an early stage of hair loss. Miniaturized hairs can be seen in various stages of miniaturization. For example your normal hair shaft is 70 microns in thickness, a miniaturized hair could be any thickness less than 50-60 microns on any particular individual. So in the earliest stage of hair loss, it might be 50 microns in thickness and over time come down to 40, then 30, then 20 microns and at some point it might just be like a tread with almost no thickness to it at all. All of these are miniaturized hairs. When people take the drug finasteride, it often reverses the degree of miniaturization such that a 30 micron hair thickness which is less than 50% of its original value, may thicken to 90% or at times 100% of its original value. That is why I like finasteride as it works both to reverse miniaturization and to stop the hairs from both miniaturizing and falling out directly (another manifestation of hair loss).
