Works for my fine 4C highly porous hair!

I have struggled for YEARS to find a shampoo that doesn't dry out my hair but also cleanses my scalp properly. I'm black and have very fine porous kinky hair texture that is prone to breakage. I also suffered from dry scalp and buildup that just seemed to never quite go away. I was skeptical of using such an expensive shampoo, but had nothing to lose. This gives enough slip and leaves my hair feeling clean but not stripped. It actually makes finger de-tangling easy in the shower, which is something I have never experienced with a shampoo prior to using this one! If you have hair that can benefit from extra protein, I highly recommend this. And for my fellow kinky coily girls with the airy fluffy fros, give this a try!!!! I also recommend K18 detox shampoo for heavier buildup followed up by the K18 leave in mask.
