Does the work when mixed with blonder powder

Works great, not as strong as 40 volume not as light as 20, didn’t see any damage. Works great.

Used it with Oxyglow Blonder powder. It did blonde my hair to a extent (some orangish blonde).

It's totally affordable. Love how easy to use. I used it with the oxyglow blonder powder. And it worked really well.

Best for coloring your hair lighter shades than the hair color you have.. Also don't use it in scalp

It really brings out the color and helps cover greys

According to price it's one of the best 👌 developer. Would definitely buy again

Used it wih OG blonder powder in recommended ratio and it worked so well.

Better developers out there. Use 20 Volume if you're bleaching pre-bleached hair.

It worked the same as the developer that was already included with the product I was using. It didn't lighten my hair or change the color, even after using this one.
