Go to Filter > Noise > Add Noise, make sure the distribution is set to Gaussian and check the Monochromatic option. Monochromatic will ensure that the grain doesn’t have any color to it, and the Gaussian distribution will randomize the way the grain is laid out, instead of being in a predictable pattern.
