Product Description
A lot of us love to start each day anew with a refreshing shower and cleansed hair, but washing your hair every day can strip it of its natural oils—with a regular old shampoo, that is.
Thanks to the K18 Peptide Prep pH-Maintenance Shampoo, suitable for everyday use, you can have your daily showers without any disruption to your hair fibers or scalp. The pH-balanced, microbiome-friendly formula creates the ideal environment for healthy hair to grow in, enriched with the brand's patented K18PEPTIDE™.
You'll get a powerful cleanse as dirt and oil are broken down, but your hair's integrity, hydration and color are totally preserved.
Prep hair with the shampoo, follow with K18 Leave-In Molecular Repair Hair Mask.
