Brand new, sealed packaging K18 Leave In Hairscience Molecular Repair Hair Mask 1.7 fl oz / 50ml

What sets this K18 hair product apart is its ability to penetrate deep within, healing hair from the inside, unlike traditional conditioners that only target the surface or bonding treatments that diminish over time.     The transformative effects of this mask are long-lasting and remain unaffected by shampooing.
