Dandruff Shampoo actually 'Prevents' human evolution, My Theory

Just because something is natural doesn't mean it's process can't spin out of control Cancer being the most extreme example . People who have dandruff often loose twice the amount of skin from the scalp as the average person. The colony size of M. globosa is also usually doubled. Dandruff shampoo also does not permanently halt the natural process it merely prevents it from going haywire as quickly. My Head & Shoulders doesn't have selenium in it instead it uses Zinc pyrithione. There are also several natural alternatives such as tea tree oil, sandalwood, and black pepper.
