POWERTOOLS Gray Oxidizing Drops - Covers Resistant Gray Hair, Adds Depth and Shine to Any Hair Color (1 Fl Oz, Liquid, Gray, Gray)

This product is amazing! It really brings out the true rich color of you factory boxed hair dye, makes your hair soft and shiny and does just what it is supposed to do which is to cover stubborn gray 100%. I highly recommend this product.

Pretty good anything to help with Gray coverage did make hair color cover more evenly and more gray easy just mix in with hair dye

After coloring my hair for many years with grey resistant product, I needed extra help. Heard about this product and had great results covering grey and keeping it covered after the first use! I am very satisfied to have used this. A hair stylist had told me about this product. It even helped the color look more natural.

The dispenser on this is not the best. Not sure if it really worked because not alot came out of bottle. I will try again!

Worked fantastic!!

Works great

For starters, the instructions are very vague. It states: total formulation of color + developer together equals: Levels 1-6 2oz add 10 drops; 4oz add 20 drops (+ levels 7-12 formulations). There is no explanation as to what “level” pertains to so I tried each formulation per coloring to determine the # of drops I need to use. Needless to say, none of the “formulas” worked. Each time I got the same results, and each time I still found grays that resisted the color. The last time I colored my hair, the color looked somewhat brassy & I could see a sprinkling of white strands near my part. (I should add: my friend is a professional stylist so I asked for her assistance to be sure I was applying the color etc correctly.)I am really disappointed with this product because I had heard it was excellent for coloring resistant gray hair but that wasn’t my experience.

Add to color it helps cover grey.
