Which is harsher?

[michiganlady1]

Ammonium Lauryl Sulfate or Sodium Laureth Sulfate? I keep on hearing conflicting information. Please help because I am thinking at this point to not use shampoo at all......

On Motown Girl's website, she says ALS and ALES are harsher than SLS and SLES. HTH.

I would think that ALS and AlES are the most harsh because almost every clarifying shampoo or shampoo that advertises getting your hair "super clean" has the ALS in it.
