User reviews

Great Product ! works perfectly with the Quck blue ! Results after 20 minutes as shown in the Pictures! Would recommend this Product!
Wonderful developer. I used it with Loreal HiColor hair color. Level 40 is the developer to use if you are going much lighter than your natural hair color. I have very very black hair and wanted to go red. I mixed this developer with Loreal HiColor in a red shade. My hair is now a very vibrant red! Level 40 is the best for going lighter!
Used with a blue bleach packet, mixed well and applied for thirty minutes. Works well !
Worked great
This is a hair lightening product that I regularly use when I lighten my shoulder length hair. I mix it with powdered bleach to apply blond streaks over Nutrisse hair color in an ash brown shade which I apply first to my roots. This works well for me. Loreal is a trusted brand by professionals the world over.
I used it with Clairol Bw2 Powder Lightener and it worked great. Within an hour, it lightened my hair from black to a light yellow shade. Although some people said 40 volume would be too harsh on your hair, I did not have that problem. It did not dry out my hair much and my hair is still very silky. Highly recommend this product to those with black or dark hair colors.
I'm giving 4 stars because I received the wrong product. I got powdered bleach instead of developer. Normally that would earn 1 star but when I contacted the company, they absolutely made sure I was happy with the results. Will order again.
