The Deep Treatment is a pretty impressive product. I had recently had my hair professionally bleached and dyed; and of course, within a week it was already fading fast. Not washing my hair (when it's thin and limp like mine) is not an option. The deep treatment is the prefect response to this. The sampler pack allowed me to keep up the layers of color that my stylist had originally crafted, and each 10/15 minute top-up has give me a few more days of very "fresh" looking hair. I've been using my sample pack for over a month now, and still have about half of each tub left to go, so I've definitely gotten my money worth.

The three pack of color conditioner has been less effective. I find that it's useful for a day to day "maintaining" of color, but it doesn't add much. The deep treatment works far better. Also, the conditioner is a huge pain to squeeze out of the bottle. It's a nice bonus; but I would not rely on this product alone to keep my color going. Word of caution; it smells pretty bad to me. Kinda like mildew. The scent is a lot like a strong hair dye scent, but on the day to day it started to make me feel nauseous. So just another small nudge against using the conditioner continually.

Needless to say, after trying out the pack, I will absolutely be purchasing more deep color; and possibly more packs to try out! If you want to see how your hair would look as a different color, I would highly recommend them!
