Is there something you can put in the paint or is there a certain kind of paint you can buy so the stairs are not slippery?  
 
Where to buy anti slip treads that glue on stairs for further traction?

put a cup or two of sand in the paint an mix it up an then apply it to stairs

Any paint place in town usually can give you info on non-slip exterior paints.  
 
If you don't want to re-paint, interior/exterior non slip adhesive tape grip might work ok as well. Here's a local in stock link. I'm sure most hardware stores carry it as well.

Or buy the stick on non-slip strips from a hardware store

has a spray version of an anti-slip, its in the spray paint aisle.

Some skateboard grip tape! It's often available in multiple colors, is usually about a foot wide, and is often sold by the foot so you can cut it and make the pads as big or small as you like. Even different shapes!

You can purchase pre-made non-slip paint products. Or, as previously suggested, you can add sand. I recommend Silica sand, rather than regular sand (should be at any paint store or department). It is finer, and does not clump like regular sand. Either product involves fairly regular stirring (using a upwards motion as well to bring sand from the bottom) or the sand will settle fairly quickly. Less stirring usually required on the pre-made products. Strongly suggest you use a actual floor paint as well, not a wall paint. Lower sheen paint also means less slip factor (though usually not quite as durable as its glossy counterpart).
