Hair hygiene

I hate when people say I’m disgusting and dirty because I only wash my hair every week or every 2 weeks. 
Like in case you haven’t noticed I am black, an African American. 
I cannot wash my hair all the time like that. That will dry it out like crazy. And I cannot be doing my hair all too often. 
Since my hair is natural, all of that manipulation will break it off like crazy. I have to go like a week or more without combing or brushing to keep up with my hair’s health. 
Then people hate on my hair because I have it in its Afro state and that I need to comb/straighten it. Like you don’t have my hair. You don’t know how to deal with it. 
I hate it all so much. Like leave me alone....
