Hello and thank you for your honest feedback regarding our shampoo. We understand that the sensory experience of a rich lather is an important part of a hair care routine. While some of our formulas are designed to be low-foaming to protect color and maintain the hair's natural oils, we understand this is a matter of personal preference. We would love the opportunity to recommend a different formula within our range that offers the high-lather experience you enjoy. Please feel free to contact our Consumer Care team Mon - Sun 10:00AM - 7:00PM EST at 1-800-543-4572 so we can provide a personalized recommendation for your hair type, we look forward to speaking with you soon!

Great Shampoo for damage control.

The shampoo and conditioner make my hair feel incredibly soft and moisturizing. I've used this shampoo since 2018 and swear by it.

Used for many years.

I’ve been using this shampoo for years and have not found anything better. Unfortunately, the price has risen considerably over the last few years so I may be priced out of using this in the future.
