What happens if you take finasteride with no hair loss? On the verge of ordering

Made a thread a few days ago. Might've been a couple of weeks ago, no idea what day it is with this pandemic. Anyway, I have been heavily researching finasteride.

Right now I don't know if my hair is thinning, or has thinned. I was worried about my hair when I was around 19, and started to obsessively take pictures and post them online. The verdict came back that my hair was light coloured, fine, straight, and I have a red scalp, I think it's psoriasis, but no shampoo has helped. Was also told I have a centre-ish parting coming from my crown. I'm 30 now.

I periodically take pics of my hair, maybe once every two months to monitor it and I haven't really seen a change - I still don't think I can see one particularly - but after cutting my own hair I started to panic, and then after my most recent hair cut, I'm concerned - yet again.

I know I've hacked at my hair so that won't help. If I take a pic directly downwards onto my hair you can't really see any scalp. If I do it under direct light, sun or artificial, you can see some scalp near my "parting" which is what bothered me years ago, but otherwise, it looks much the same as it did then. My issue is when I take a pic of the top my hair at a slight angle - you can see more scalp, especially in direct light. Now, my hair does stand up naturally, but even with product in flattening my hair, you can see scalp at this angle. Also, I haven't included a pic, but if I wet, or use product in my hair and stick it up, take a pic against light, you can see right down to my scalp and it looks terrible. Now I don't know if that is thinning, or just straight, fine, light coloured hair standing up, which means light is able to get through and then show scalp... I don't know.

So yeah, I don't know whether to jump onto finasteride, just in case. My only worry is, if this is just my hair, and it's not changed in 10 years, would I be taking the medication for no reason - and potentially going through the side effects it brings.... for no reason?
