I dyed my hair before and when I used this product I found that I got very average results. There was not anything unique about it. I did not feel like it lightened the color or enhanced it in any ways shape or form.

So I do not know what it is when it comes to Tresemme shampoo, but it does not do anything but clean my hair. This one made it almost impossible for me to get a my hair brush through my hair easily.

I have coloured blonde hair and this definitely doesn't help with it! The price is right and it smells awesome but it doesn't help with keeping the brass away! It might work better with other coloured hair.

If I have to basis this on what this product intends to do, it did not do that. I get my hair professionally coloured blonde. My hair gets brassy about 2 weeks after the salon. Usually I have found purple shampoo helps retain the blonde. This still allowed my blonde to become brassy. So disappointing.

There is nothing wrong with this product. It works, and does what it says. But, when compared to other similar products, the price for it didn't make it very worth it.

for the price, this is the best color protection shampoo that Ive found.

It was ok, it was as if i bought some shampoo that wasnt for color treated hair. And my hair did start to lose its color troughout the washes.
