Do Miniaturized Hairs Turn White and Curly?

Hi Im a 23 y.o male (using propecia for slight receding hairline)
Over the course of a year random hairs have started to shrink, turn curly and white from hairline to crown, sometimes in clusters. Its not noticable to strangers and I have been able to pluck them out so far. Of course I thought that this might be normal miniturization but my hair has a thick white base with a thin tip instead of the “beige/straw colored fading away” I identify with miniturization. And of course I have considered whether this is normal graying, but you see many full heads of gray hair and if this keeps up I will instead be left with a head of small white wiry growth. Any suggestions ?
Thanks

As you are in Los Angeles, I would be happy to do a miniaturization study on you and let you know if what you are observing is the beginning of the balding process. I have an office in Los Angeles. Generally, miniaturizing hairs don’t change color. I’m not sure what you’re seeing.
