Good, but Lacking!
Bought this hoping to replace the Bill Rich MSM shampoo I had used for years. It was GREAT! THIS ONE, not so much. Leaves hair dry and flying! Seems to feel dirty/oily within 18 hours. RICH'S didn't. Takes twice as much of this to wash hair (Men's short style) than the RICH item! Bill Rich died, and his kids have not kept the products in stock. This is WAY OVERPRICED for what you get. Cannot find a good MSM shampoo except this rip-off, so...
