I was born a natural blonde, but as I got older my hair turned a light brown but maintained naturally blonde highlights. Once I moved from the beach and into the city, my highlights turned brassy and my light brown hair a darker brown. I started using Malibu C Hard Water Wellness Remedy and after the second use, my brassy reddish orange tips are BLONDE again!!! The rest of my hair is returning to its normal light brown with less reddish color.
