Affirm 5 in 1 Reconstructor is a unique blend of micro and macrofibrous conditioners that is applied immediately after rinsing the relaxer from the hair and before the Normalizing Shampoo. While substantive conditioners are deposited well within the hair fiber, the hair is restored to its normal pH of the hair. (NOTE: Deep conditioning is still possible at this time because the upper mantle of the hair is still alkaline--approximate pH of 10.0--and the cuticles remain partially open). 5 in 1 Reconstructor is for use on damaged, fine or limp hair. It's also recommended as a deep penetrating moisturizing conditioner for regular salon reconstructive treatment services.
