Hair washing / OCD

OK so i have OCD , and lately I've been wanting to stop washing my hair everyday because it's getting so dry and even more frizzy and I'm guessing it's cause I wash it everyday , well anyway with my OCD I find it hard to not wash it everyday because I just feel dirty if I don't .

So my question is . If I skip washing my hair does that mean my hair is dirty or has germs. Germs are my biggest concern I feel like theirs germs on my hair If I don't wash it .

So is there or no ?
