Reviews Summary
Customers say this shampoo thoroughly cleanses without drying out their hair. Many reviews mention how effectively it removes product buildup while leaving hair soft and manageable. Users particularly appreciate that it produces rich lather and only requires a small amount per wash. Common feedback includes that hair feels clean and refreshed after use, with results lasting several days. While some note the price point is high, most find the weekly deep cleansing results worth the investment.

    My hair has never been healthier

    I have used this shampoo for over a year. I also wash my face with it while washing my hair. I think the peptides may help reduce my fine line wrinkles on my face. It definitely keeps my hair healthy and shiny. I absolutely love this product!

    Let’s talk about the scent

    Absolutely love this product. I have tried to find a deduction that I felt like worked with the Hair💇🏼. This does not leave my hair feeling damaged and dry. It actually leaves it feeling nourished and healthy.
