L'Oreal Feria Multi-Faceted Shimmering Color, 40 Deeply Brown, 1 ea, 3-Pack

I turned 65 and wished to go salt and pepper naturally, but greatly disliked the color line and regrowth discoloration. And No matter what salon I went to for salt and pepper hair color transformation. I always got a botched up hair cut, and hair color. Extremely Frustrated and bankrupt, I decided to take matters into my own hands. I bleached my hair to the lightest I can get. Searched for hair colors closest to what might come closest to salt and pepper color. I purchased the L'Oréal Multi Faceted Shimmering Permanent Hair Color S1 Smoky Silver. It's still not salt and pepper, but is close to it. The only issue is the color dose change to a dingy yellow color, I tried a purple deep conditioning mask, and it was never the same as when I first used the dye. The product is awesome, I was ok with it, but don't know how to maintain and keep it from changing color.
