Sulphate is an ingredient that causes shampoo so lather.
The main thing keep in mind that when thinking about sulphates is
that they are chemical detergents. It means that sulphates are
extremely effective at removing dirt and oil. Sulphates are harsh on
the hair and scalp, so they can strip away that natural moisture
that keeps hair shiny and soft.
Sulphates can cause a number of problems for hair including drying,
irritation, fading of colour and even hair loss.
Paraben is used to refer to a group of chemicals, mostly synthetic
that are commonly found in health, beauty and personal care
products. They act as a form of preservative, preventing the growth
of potentially harmful microbes such as bacteria or fungus, thereby
increasing shelf-life.
