Cleans my hair so well
First time trying a detox shampoo but wow compared to other regular shampoos it lathers well, comes out black, and makes my natural blonde hair blonder

After testing the K18 Peptide Prep Detox Shampoo for two weeks, I’m genuinely impressed with its performance. As someone with color-treated, heat-styled hair, I’m always looking for products that detox the scalp and strands without leaving my hair feeling dry or over-cleansed — and this delivered exactly that. Cleansing Power: This shampoo provides a deep, clarifying cleanse that removes product buildup, excess oil, and environmental residue in just one wash. My scalp felt noticeably cleaner, and my hair had more natural volume at the roots. It’s strong enough to reset your hair without feeling harsh or over-drying. Gentleness & Formula: Despite the deep-cleaning effect, it doesn’t strip the hair. It’s sulfate-free and feels balanced — no squeaky or tangled feeling afterward. It lathers well with just a small amount, and the clean, subtle scent is refreshing without being overwhelming. Compatibility: It works especially well as a prep step before using bond-building or peptide-based treatments like the K18 leave-in molecular repair mask. I noticed that post-shampoo treatments seemed to absorb better and left my hair feeling smoother and stronger. ✅ Pros: Deep-cleansing without dryness Great prep for repair/bonding treatments Clean scent, good lather Safe for color-treated and damaged hair A little goes a long way ❌ Cons: Not intended for everyday use — best 1–2x per week (but that’s typical for clarifying products)
