## Description

KeratinUSA Hair-Straightening Formaldehyde-Free Enhanced Formula Treatment helps to restore hair to its natural state, controls hair loss, and manages frizzy, weak, coarse hair. This restoration system combines a high percentage of pure keratin and acai berry extracts with antioxidants that infuse deeply into the cuticles of your hair. This system restores the lipids in your hair, protecting it from humidity and free radicals. This treatment is not a permanent straightening but a smoothing treatment that can be used on all hair types such as chemically treated, colored, permed, relaxed, straightened, highlighted, and bleached with results that last up 3 months and fade away gradually as hair is shampooed. This amazing product heals, repairs, moisturizes, nurtures with keratin and protects damaged hair. Moreover, it eliminates frizz and curls, emits no unpleasant odors and can be used on all hair types.  The Daily Maintenance, Silk and Activator Treatments create the perfect protective barrier when styling because they bond with the hair and they activate with the heat of a blow-dryer or flat iron. They create a lubricating barrier between the hair and heated styling tools, and they deposit a thin layer of pure keratin onto the hair, which will prolong the life of the keratin hair treatment. Their deeply penetrating actions repair and revitalize hair during blow-drying and ironing and close the cuticle to entrap the nourishment. By adding them to your daily hair-styling routine, you will gain smoother, shinier, healthier and more manageable hair.
