Ok another color question let's see my hair is a reddish brown color so I guess what would be brunette sort of. Don't know its got some blonde in it too. All natural of course though. I'm just an odd one though I guess lol.
There does appear to be more Keratoconus in certain masses. Which does suggest there is a genetic component to KC and KC can run in families (and sometimes it seems to skip a generation or two) however sporadic, it occurs with no rhyme or reason sometimes and with the complete picture always eluding us and what if any other factors and/or triggers, are involved.
The research has accelerated a lot in recent years and most likely due to patient advocacy, as seen here!
Stay well !
