My Eyebrows Are Thinning For Some Reason?

[Distance68]

About three months ago I noticed that my eyebrows were getting thinner and thinner, for example when I wash my face two hairs from each eyebrow would come off and and also when I woke up and ran my fingers through my eyebrows at least one or two hairs from each eyebrow would come off. I thought maybe this was a one time thing and it would get better because my eyebrows are fairly thick and grows back super fast. Recently though, my eyebrows have gotten worse. I would lose about 6 hairs from each eyebrow daily and get tiny bald spots that would last about a week until new hairs cover it. Looking at my eyebrows they are not super thin but I'm just worried that it will get worse as more time passes. Also to mention, my eyebrows are really dry and flakey, kinda like dandruff. I know it's only my eyebrows because the hairs on my head are normal. Dunno if age matters, but I'm 18

Yes. When I first tried finasteride i noticed my eyebrows were thinning, especially the top

Eyebrow thinning is kind of normal to the extent that your facial features are changing as you go through puberty.

It shouldn't be anything to worry about but take a picture of them, then take another in a month and do some comparison.
