I detangle once a week when if I plan on wearing twists for that particular week, and twice a week if I have my hair out. My hair gets easily matted, like yours, if I leave it out for more than 2-3 days. I think if you're being careful with your detangling process, then the amount of times you detangle in a week shouldn't be an issue.
