I'm a 3C/4A hair type. Before MSM, my hair would frizz more easily, thus the curl pattern was not well defined. After my first month with MSM, the curl pattern not only has improved definition, but my hair is softer and when pulled back it has nice waves.
My eight year old niece looked at me today and oooh-ed over the wave pattern. She instantly ran her hand across my head and told me it looked nice. Children can be frighteningly honest sometimes, so it was a good feeling to have that reaction.
