The shampoo offers an effective solution to the problems of hair greying and hair loss related to the natural genetic age of the hair as well as environment and civilization-related factors (stress, poor eating habits, environmental pollution) which cause premature hair aging. The shampoo effectively cleanses the scalp and improves hair condition. Thanks to the potent effect of concentrated naringenin, the shampoo works in two ways: it slows down hair aging and restores the natural hair pigmentation. Naringenin activates mitochondria which are critical for life processes in cells, extending their life span and silencing the genes responsible for the suppression of pigment synthesis. This way it slows down hair graying and reduces the number of gray hair. Combined with nut extract which is a rich source of phytopigments, it gradually darkens gray hair and restores its natural colour. A highly effective caffeine and Natural Growth Factor FGF complex (which is the subject of a patent application) significantly strengthens hair follicles and extends their life span (the growth phase), making hair less prone to falling out and thinning. D-panthenol and cationic polymers with irritation soothing and regenerating properties restore the natural pH level of the scalp and help to maintain optimum hydration.
