While in the shower, I apply a very small amount of Lucky Tiger Face Wash to a wet cheap synthetic shaving brush (like those that are in the cheap drug store shaving kits). Then to my wet scalp, I lather up the Face Wash on my scalp and face. Again, it only takes a scant amount of product applied directly to the brush to lather up the entire area.
If I'm going to shave, then I don't bother trying to rinse it completely off, thereby letting it act as a pre-shave lotion of sorts. Otherwise, I rinse it completely. This product rinses easier than shampoo. I can't speak more highly of Lucky Tiger. It has made a huge difference in my skin quality.
