JKS The Mask actually cures and revitalizes hair by infusing both modern science and anti-oxidants from fruits and a variety of berries, including the ian acai berry. Unlike less superior products, luster and strength is brought back to tired, lifeless strands by fortifying the cuticle shaft, layer by layer, until it reaches the core, otherwise known as the cortex. Only then, by truly nourishing the cortex, can brilliance and silky radiance be restored. The mask is a must- have tool for anyone who is looking to take their hair to new lengths. At some point or another we have all looked at our “roots” and have noticed that our hair is growing, but never understood why it doesn’t seem to be getting any longer. Hair that is brittle will never grow past a certain length because hair that is weak at the ends will literally break off at the tips. JKS The Mask will fortify ends, strengthening them from the inside out. We all inflict unforeseen damage on our hair. Some of these methods are obvious, some are not: ponytail holders, heat styling, coloring, wind, drug store products and even chemicals found in tap water. WEEKLY TREATMENTS ARE A MUST. Other conditioners try to fool the consumer into believing that the shine left on the hair is natural and healthy when in reality it is due to wax or other less desirable, less costly components that cause build up, creating faux softness and shine. In time this build up creates far more damage than the good it claims. With JKS The Mask only the most superior ingredients in their purest form are utilized. That translates to no build-up, and no residue. The effects you see - the luster and the shine - is truly a reflection of the state of the health of your hair. With JKS there is no smoke and mirrors. Like all things, rebuilding and reconstruction take time. EVERYONE IS ENCOURAGED TO USE THE MASK. Highly porous hair looks dull and can not preserve color as well.Sulfate free, never tested on animals. 3-3-1 Schedule: 3 consecutive days apply The Mask after shampooing, then... 3 applications, applied once a week over a three week period, then... 1 application per month to maintain healthy hair.
