Combo Includes: Keragen, Hair Smoothing Keratin Treatment Chocolate Forte 32 oz + Keragen Clarifying Shampoo 32 Oz. The Keragen Chocolate Forte Smoothing Treatment is a Maximum strength treatment that tames and straightens even the thickest, most resistant curls while rejuvenating and protecting the hair with keratin and collagen. This treatment is formulated for medium to course hair and has been proven to deliver frizz-free, irresistibly smooth results that will last up to 5 months when properly maintained with Keragen’s collection of quality aftercare products. Keragen Pre-Treatment Clarifying Shampoo is formulated to remove excess impurity build up in the hair while providing the ideal pH level to open the hair’s cuticle for maximum treatment absorption. Opening the hair’s cuticle is an essential first step in preparation for treatment. Without this step the treatment will not be able to properly absorb into the hair which will greatly reduce the effectiveness.
