If you color with henna you know it doesn't last anywhere near as long as regular hair dye. This conditioner does help keep the color longer. I mix it in with my favorite conditioner.

Bought the larger bottle because 6 weeks worth was needed for "thermogenic response." Took as directed and initially noticed a lot of dry mouth but nothing else. Very disappointed in this product.

I have a lot of gray and had been using salon hair dye up until a friend lost a kidney to cancer. When she asked her oncologist what caused the cancer he didn't hesitate-he told her second hand smoke and hair dye! I didn't realize how toxic the ingredients in regular dye were until I started reading up on it. The FDA does not regulate hair dyes, you're on your own. Even though henna doesn't last as long, you can do touch-ups or mix a bottle of your favorite color into a bottle of your conditioner to keep the color fresh (just let the conditioner sit on your hair for 20-30minutes). I would give Surya cream 5 stars if it lasted longer but a healthy hair color is more important.
