I had a client last week who had previously done ombre style highlights to a level 9. She came back in about ten weeks later and her previous highlights were about a level 7-8 orange. She was only booked in my day for a base color touch up. So I decided I would apply her touch up and when at the shampoo bowl, would use Malibu C Hard Water Wellness Remedy packet on her ends. I could not believe what I saw after only 5 minutes. Her highlights were back to their previous glory. I simply did a violet shampoo, and finished with a conditioning treatment.
