The base cream used for chemical straighteners serves the important function of creating a protective layer on the scalp and hair. This layer acts as a barrier to prevent the harsh chemicals in the straightening solution from directly coming into contact with the skin, which can lead to burning or irritation. By applying the base cream, stylists help minimize the risk of chemical burns and ensure that the treatment can be performed safely.

While conditioning the hair and enhancing shine are important aspects of hair care, they are not the primary function of the base cream in the context of chemical straightening. Conditioning agents may be included in the formulation of some straighteners, but their primary goal is not to serve as a conditioning treatment. Additionally, the base cream does not involve coloring the hair, as that is typically the role of a different product designed specifically for coloring.
