I use this mainly on clients who have had previous color in their hair, it’s a great consistency to mix color and bleach with. The Gel 20 volume is my main go too with any client wanting an amazing color in an affordable time!

I felt that this developer was incredibly worth my time and money. Not only was it strong and efficient enough to obtain the hue / color I wanted, I saw a lot less damage, personally.

This gel developer has been great. My aunt who is a hairstylist uses this to highlight my hair. I never find my hair to be course or dry. I think this to all of the Redken products I’ve used over the years.

I am a huge fan a Redken color! I have used both permanent and semi permanent color both on my self and my clients. The color is rich and beautiful. In my salon it’s one of our major color lines. Colors never disappoint, and am very satisfied. I would definitely recommend Redken!

This is good hair color if you’re not trying to go lighter. It made my hair very very very dry and coarse. I dyed it blonde and had to use the bleach they had and it was hard to even comb through it after a shower

Something about these developers that does not wreck your hair as bad as some others I have tried. I was in the hair industry before and the Redken line is what we used.

I'm a licensed hair stylist and I've been working in a salon for the last 7 years. I love this product but I wouldn't use it if you're not a licensed hair stylist!
