I use to always use Redken BodyFull shampoo and conditioner, but it is discontinued. I tried and tried to find something new. I finally asked my salon and they suggested this since I do have natural silver streaks. I love this shampoo. It is gentle, gives my great shine, bounce, and lift. The scent is very gentle and nice. I highly recommend if you are silver like me. I know that some people mentioned it dried their hair, not me. My hair with other brands is dry, this is very moisturizing for me. I wash my hair everyday and sometimes twice a day.
NOTE: The shampoo is purple. That does not bother me, but I will let you know that it will stain and it will not come out. I did not realize I left some in the white grout of my shower stall, my grout is now purple. Apparently I am a violent scrubber to the point that some of the purple got on my bathroom door. My interior doors are catalyzed white lacquer and I scrubbed and scrubbed and it won't come out.
UPDATE 1/22/2018: After constant use it feels like it builds up and removes all bounce from my hair. And with constant use it dyed my gray hairs blue. I had people ask if I was dying my hair blue. And sometimes I don't feel like sitting on the bathtub floor to wash my hair since it stains so bad. I decided to stop using this.
