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.

    This shampoo is awesome. Being that my hair is relatively dry, this shampoo makes it only feel clean yet still moisturized. No more dryness after detox!

    Strips all metals. Oils and old product

    Absolutamente loved this product. It stripped anything that was lingering in my hair and prepped before I needed to style on fresh hair.
