What is the difference between shale and tar?
Coal tar is a petroleum product and very damaging to one’s all around good health not to be used on the body, while shale is a rich natural deposit of decomposed trees. Millions of years ago, large forests of ferns and evergreens decomposed and formed large reservoirs underneath the earth surface of very rich shale. We get our shale from Germany in a natural state which is rich in various rare trace minerals. These trace minerals are healing in varying degrees for the scalp and hair alike. This is a cure all for a multitude of scalp problems, plus a general radiant effect on the hair itself giving it new life force and brilliance. There is no comparison between tar and shale. And one should avoid all products with tar/coal tar in its ingredients.
