Question on MMR

Is there any exact way to raise your MMR faster? Or at least get it going back up at a slow but constant rate? I would like to end this streak of winning 3 games in a row then loosing all the LP I've earned by loosing 1 game.

I know it's my fault for having that kind of loosing streak, But that is gone now. I've been winning more then I lose and i'm finding it difficult to climb back up the Elo I was at before the loosing streak. Any tips/help is appreciated thank you.
