    Very good at cleansing!

    This is a very good medium-strength cleansing shampoo! It’s not too stripping and is probably beneficial for people who don’t use LOADS of product. Additionally it has a very neutral smell with good slip - I tend to detangle my hair with shampoo so this works for me! I could definitely reach for this for my monthly wash if I’m not using gel or wax :)

    Thank you so much for this thoughtful review, M! 💛 We're thrilled to hear that you're loving the medium-strength cleansing power of the PEPTIDE PREP detox shampoo and that it's hitting that perfect balance of being effective without being too stripping! ✨

    It's fantastic that you appreciate the neutral scent and good slip - we love that it works so well for your detangling routine! And we're excited that you've found it's perfect for your monthly wash when you're not using heavier styling products like gel or wax. That's exactly the kind of versatile cleansing power we designed it for!

    Thanks for your wonderful 4-star review and for sharing such specific details about how it fits into your routine! 🙌

    My hair was ruined by bleach over bleach highlights. My new hairdresser told me to try k18. It is actually a miracle. I’ve had so many compliments on my shiny hair and it has also grown for the first time in years. I will be using this all the time now as I can’t go without it. Nothing compares. Thanks k18
