Review on MODAMODA Reducing Shampoo Darkening Minimizing by Amanda Nunez

three different age groups use this shampoo for two weeks; 70's male with 2-3 inch long and originally white hair + used to dye hair brown, 60's male with short (less than 1 inch) and white hair + no color (white only), female 50's-1990's with straight shoulder-length hair, gray hair without a perm was used to dye hair in light colors. '70s hair has changed so quickly; only used 3 times all his hair (including the roots) changed to a natural brown. 60's hair took longer than 70's hair and now it's turned dark brown (including the roots)! '50s hair slowly changed; darkens, but the root is still white. She continues to use the shampoo every day but the root doesn't seem to have changed. I heard it takes about a month to replace the root part. be patient and wait for a miracle.
