Dreadlocks, skin rashes, and hair issues: Has anyone dealt with this?

I’m starting to get a little freaked out about what’s going on with my scalp—I’ve got this patch of ringworm near my ear, and I've actually noticed some hair falling out right where it is. My dad even went as far as putting some ointment in my ear after he warned me I’d regret getting dreadlocks because my hair will never be the same once I shave it all off... apparently, it'll just look thin and sparse. Usually, I don't pay much attention to his constant lecturing, but honestly, I haven't been able to sleep lately.

Is that even a thing?
I did a ton of research before I actually got them done, but I totally missed reading about this specific issue. I know there's stuff about how wearing hats too often can lead to thinning hair in men, but could there be a connection here?

Hoping someone out there might actually know something.
Also, has anyone dealt with ringworm before? Any tips on how to clear it up?

Regarding that lichen issue, you really ought to hit up a dermatologist so they can get you some actual meds. Honestly, dreadlocks are awesome and all, but they’re basically magnets for every random bacteria under the sun. My son actually gave up his nearly butt-length locks specifically because of that kind of stuff.
Your dad is kinda right about certain things, but 😉 don't sweat the "thinning hair" part too much. Just keep in mind—and you probably already know this—that if you decide to ditch the dreads, you're looking at a pretty short haircut to start over.
But seriously, the most important thing is that first bit: go see your doctor or a dermatologist to get that lichen sorted out.
