We got this for just a supplement to our diet, not really expecting much. The hacky little cough I had disappeared, my daughters lung wheezing lessened, BUT, my 69-year-old bald son has begun growing a whole new crop of hair! When I crew-cut his remaining hair, I leave the new growth about 1/4 inch long now, and folks are beginning to comment on it. When it is fully grown, maybe I should send a photo? Try it!
