PH balance.


Some shampoos are not ph balanced to your hair and body. Humans ph balance are different then that of say dogs or rabbits. Alot of company do and used to test on animals rather it be mice to dogs etc. So when it says ph balance you need to check to see if the bottle says not tested on animals. This means either they tested on people or they only tested it with litmace (sp) paper. PH scale is 1-14 our shampoos should be anywhere between a 5-9 closer to the middle is better.What is the chemical difference between harsh shampoo and mild shampoo?
The grade of a shampoo is dependent upon the base content. Much like regular soap there is a certain amount of base contained in the shampoo product that is important in the removal of dirt. However, in the event that hair folicles are too sensitive to the basicity of the product it is either pH balanced (fixed at a certain level) or changed to a milder level that makes it useful and manageable.
