when products are formulated one tries to balance the ingredients in the formulation to optimise the properties one
wants from the finished product. in the case of so called ‘colour safe’ shampoos that protect and lock in hair colour it is
a matter of formulating with lower surfactant levels, so that the shampoo is not as aggressive on the hair, and high levels
of proteins, film formers, moisturizers, humectants and sunscreen to protect the hair from environmental damage. for
‘colour safe’ conditioners again it is a matter of formulating with high levels of proteins, film formers, moisturizers,
humectants and sunscreen and also balancing the ph so as to close the hair cuticle.
