The Sanity by Essations Collection is formulated for those with a sensitive scalp. This gentle yet effective relaxer system is formulated with our tri-lanolin blend, a mixture of 3 different types of lanolin. Usage of this mixture demands lower levels of the active ingredients, causing the relaxer to be gentle to the hair. Tri-Lanolin Blend enables the relaxer to thoroughly straighten the hair. It causes the relaxer to penetrate the hair strands quicker, resulting in a fast break-down. It improves the lubricity of the hair, making it more pliable.
