What really makes a quality shampoo?

If a company is paying top dollar for a raw material,  it’s because that raw material was sourced ethically.  Usually it has a dual function, and the components won’t break down as fast . The supplier likely  has a knowledgeable support team as well.   They know a lot  about that material.  Where it came from, how to use it.  A good raw material supplier will have it all and that’s what makes a “good”.   The  raw material costs in this scenario are likely high.  Inexpensive raw materials  will break down.  They won’t perform as well, and most likely they are not coming from a good place.  They also will not come with good support and most likely are not eco friendly anywhere in the process.   When raw materials are delivered correctly, they are added to the manufacturing process in the right order, at the right temperatures, at the right pH.  Inexpensive products have cost cutting manufacturing.   They will cut corners to save money and ultimately produce a lower grade  product with a shorter shelf life. 
Dimethicone is a type of silicone, which comes from heating sand with carbon at high temperatures. Dimethicone is a popular ingredient in many cosmetics, such as skin and hair care products, as it smooths over rough surfaces and has a velvety texture.    A dimethicone molecule is like a lego, a supplier can build that molecule however a brand wants  and a brand pays  for specifically  made dimethicones.  They can attach functional groups to the molecule in different ways  to perform differently.  Like building something out of lego.   You can have a low viscosity dimethicone that might cost less than a high viscosity dimethicone.  Same ingredient name on the bottle, but has a totally different performance. Molecular weight also plays a part in how silicones perform and what they cost.  Again, a lot of products have the same label name,  but how they’re made determines the performance and different costs associated with them.  

Just because something has the same ingredient on the label means almost nothing.    There are general life rules that apply to choosing shampoos and there are also always exceptions.   “You get what you pay for” is a pretty hard and fast rule.   But many times you don’t get what you’re paying for if the marketing is well done.  On occasion you will get a lot more than you pay for because a brand is discontinued and it ends up on a “dollar store” shelf.
