Who it is for
This K18 treatment may be for you if...
Your hair feels weak, dry, brittle, stretchy, porous, rough or sensitized from bleach, balayage, color, smoothing services, blow-drying, flat ironing or chemical processing.
It is also a great option when you want a more focused repair routine, especially when your hair needs more than a traditional hair mask.
Important
Use it differently than a regular hair mask.
K18 is not used like a traditional conditioner. For best results, shampoo your hair, do not condition before K18, towel-dry, apply K18 and wait 4 minutes before styling or applying other products.
