Is it ok to wash my hair as soon as I get home? Will I be blind or will I get rheumatism in the future? I'm 20?

Recently, I started to wash my hair everyday as soon as I get home to squeeze the wax off my hair. My job is a video editor and my usual traveling time from office to home is 1 hour and 30 min to 2 hours where I just sleep. Last night, my parents and siblings said that I should stop doing that because I might be blind or get body complications in the near future. They said that I will just realize that when I get old. How is it true? I researched about this but I did not get any scientific explanations about this that's why I am still bothered. ( Mga pinoy sumagot din kayo! Makati to Las Pinas ang byahe ko pauwi. :) ) Thanks for answering guys.
