How to Deal with Severely Curly Hair in the Rain!!!

I was born with extremely curly hair.

People with truly silky, straight hair are the object of my envy my whole life. Fortunately, the hidden part at the back of my head is strangely quite curly, so people don't realize it until I mention it; they are usually surprised then. Haha.

If I get root straightening done regularly, it stays okay for a few months, but it's way past that time now. Plus, with the summer rainy season coming up, it gets even more of a mess, looking like a worm. Is there a temporary fix or any tips or methods to reduce the frizz even a little?
