Really disappointed, especially as a loyal customer. I paid a significant amount to have my greys covered, but after only ONE wash they were already clearly showing through. I had been out of town, so I contacted the salon a few days outside their 10-day policy. Despite explaining that I had only washed my hair once, they refused to correct the colour unless I paid again. They offered a free hair mask instead, which obviously doesn’t fix failed root coverage. Very disappointing service
