I usually enjoy TRESemme' products, but this one disappointed me a little. I bought this at one point to see if it really helped my color "thrive" so to speak. I paid a little more than I wanted to, but I had a gift card, so I was okay with the price. The first time I used it, I liked it. I liked how it smelled on my hair a lot. My husband commented on how much he liked the scent in my hair and it definitely made me smile. That won points for the shampoo. Also, my hair felt very light and clean, just how I like it to feel after using a good shampoo. I did not notice any difference in my color, but I would not expect to after the first use. However, after a couple of weeks, I noticed that my color was dimming and it was definitely not thriving because I was using this shampoo. I did not notice that my color lasted a little bit longer, but not all that much to really make a difference. For the cost of the shampoo, I would have thought it would have worked better to preserve the color I had used on my hair. I would recommend this shampoo if someone is looking for a shampoo with a great scent, but not necessarily for color preservation.
