What type of relaxers do not require a base cream to protect the skin?

No-base relaxers are formulated in a way that they can be applied directly to the hair without the need for a base cream to protect the scalp and skin. These relaxers contain ingredients that minimize irritation, making them suitable for application without a protective barrier. This characteristic allows for a more straightforward application process, particularly in sensitive areas.

In contrast, cream relaxers generally do require a base cream to provide a protective layer to the scalp, which can help prevent irritation during the chemical process. Base relaxers are similar in that they necessitate a base due to their stronger formulations, which can pose a greater risk for skin sensitivity and irritation if applied directly. Thermal relaxers involve the application of heat in conjunction with the chemical process, and while they may alter the application method, they likewise do not eliminate the need for protective measures unless specifically designed as no-base options.

The unique formulation of no-base relaxers distinguishes them in that they can safely be used without additional protective products.
