Rated 5 out of 5 by from Prepped. Primed. And peptide powered Verdict: This shampoo means business — in the best way. If your scalp’s been screaming for a reset or your hair’s been weighed down by product buildup, Peptide Prep Detox Shampoo is a total game changer. Pros: ✔️ Deeply clarifying without drying ✔️ Leaves scalp feeling fresh and balanced ✔️ Peptides help support scalp health and hair strength ✔️ Color-safe and gentle enough for weekly use ✔️ Ideal prep before masks, treatments, or extensions Texture + Scent: Lightweight gel texture with a subtle, clean scent. Think spa-day vibes without the heavy perfume. Best for: • Stylists prepping for a color or extension service • Clients needing a weekly scalp reset • Anyone living that dry shampoo lifestyle 😅 How I use it: 1–2x a week before my regular shampoo or treatments. I let it sit for 2–3 minutes for max impact, then follow with a hydrating conditioner or mask.

Rated 5 out of 5 by from Amazing!! Love this stuff! It works very well in combo with the K-18 leave in mask! As will most other professional products I do wish companies would formulate amazing products to have less hormone distrusting and other chemicals in it, so I hope K-18 company comes out with cleaner formulations for future. Product total works though and I will continue buying for now!

Rated 5 out of 5 by from Best clarifying shampoo I absolutely love this shampoo. It completely removes all buildup without drying or damaging it. I have used it with and without the K18 leave in and I did find that it allowed the treatment to do its job better. A little goes a long way.

Rated 5 out of 5 by from Better than Malibu for Hard Water Mineral Build Up Activated charcoal gives an unexpected color to the shampoo, but I find this to be the best solution for removing hard water mineral build up without fading color treated hair.

Rated 1 out of 5 by from Not recommended This was recommended in store. Didn’t work for me, my hair ends up oily really quickly. Not a fan, I also have dry scalp and it irritates my skin. I use it once every other week sometimes every 3rd week. I wanted to love it.

Rated 5 out of 5 by from Game Changer I live in Florida, our water is hard here. The combination of K18 Detox Line takes the worry out that the minerals in our water will expose to much warmth in the color or it will not penetrate all the way through.
