I have tried many different color care shampoos over the years with mixed results. The BioInfusion brand is supposed to be a higher end brand and I have tried other varieties of this shampoo but have not been very impressed with any of them. Effectiveness I purchased this shampoo because I had a coupon for it and needed a shampoo that would help maintain my color. My first impression of this shampoo came when I opened the bottle and poured some of the product on my palm. The consistency of the BioInfusion shampoo was runny and the scent was unremarkable. I would not say the scent was unpleasant but it was not strong enough to make much of an impression and the smell certainly did not linger. I attempted to work the shampoo through my hair but found that I needed to add more product to cover my whole head. The BioInfusion did not lather very well and when I was drying and styling my hair, it just felt dry and unmanageable! I really can't comment as to whether this shampoo helps maintain hair color because honestly I only used the product a few times before tossing it out! I was unimpressed with the BioInfusion Color Care shampoo and would never recommend this brand!
