The safest and most effective system for straightening, iStraight System is a permanent hair straightening (Thermal Reconditioning) system that utilizes 3 solutions strengths, each tailored for different types of hair. Whether the difference is in hair texture, curl type, or condition (such as highlighted, bleached, or even pre-relaxed hair types), there is a solution to meet the specific needs of each individual. The strongest benefits to the iStraight solutions, when compared to competitors’ products, are the high levels of collagen proteins, 7 natural oils, cysteamine, and other proven hair conditioning ingredients. Collagen is the main structural protein of connective tissues in our bodies and is a major component in hair growth because it fights off free radicals that can affect hair texture. Collagen can strengthen hair and increase an individual strand’s diameter as well as providing structural support. Additionally, a high cysteamine concentration reduces the chance of over-processing and promotes a stronger return of disulfide bonds, resulting in healthier looking hair with a treatment-like finish. Natural oils, including Avocado, Rosemary, and Lavender, work to create shine and provide a moisture barrier to keep the hair from drying out. iStraight clients are highly satisfied with the results, that are natural-looking, STRAIGHT, SHINY, SILKY, BEAUTIFUL HAIR!
