Brand: K18

Color: Beige

Features:

  • 4-Minute Molecular Hair Repair Treatment: A leave-in peptide hair mask designed to repair and reverse damage at the molecular level for stronger, smoother, more resilient hair in just 4 minutes.
  • How It Works: Patented K18PEPTIDE repairs hair at a molecular level to reverse damage from bleach, color, chemical services, and heat*. The biotech-developed peptide mimics and clicks into hair's keratin structure to reconnect polypeptide chains and disulfide bonds for strength along the length + width of hair.
  • Works on All Hair Types: Because our hair treatment works at the innermost layer of the hair rather than only targeting the outer cuticle like many deep conditioning hair masks, it's effective on all strands, even coily and curly hair.
  • Boosts Strength + Smoothness: Helps improve texture, manageability, and bounce with a highly concentrated hair cream formula with detangling and softening benefits. Most see results after 2-3 uses.
  • How to Use: Shampoo, skip conditioner, and apply 1-3 pumps of the leave in hair mask to clean, towel-dried hair. Let sit for 4 minutes, do not rinse, then style as usual. Use for 4-6 consecutive washes, then as needed.

Frequently Asked Questions

Frequency depends on hair type: oily scalp types can wash every 1–2 days, while dry, color-treated, or damaged hair benefits from washing 2–3 times a week to preserve natural oils. Anti-dandruff shampoos are most effective when used 2–3 times per week as a treatment.
Yes. Sulfate-free formulas in our range are specifically designed to protect color vibrancy while providing effective cleansing. Avoiding sulfates significantly reduces color fade compared to traditional shampoos, extending the life of your color treatment.
Our hair care products feature scalp-supporting ingredients like ceramides (to protect the scalp moisture barrier), niacinamide (to soothe irritation and reduce sebum), hyaluronic acid (to hydrate without heaviness), and zinc pyrithione (to control dandruff-causing fungus).
Yes. Applying conditioner from mid-length to ends after every shampoo prevents dryness, reduces frizz, and protects against breakage. Leave conditioner on for 1–3 minutes before rinsing. For very damaged or coarse hair, a weekly deep conditioning or hair mask treatment is also recommended.
Most products in our hair care range are formulated for all hair types — straight, wavy, curly, coily, fine, thick, and color-treated. Universal formulas deliver balanced cleansing and conditioning without weighing hair down or causing buildup on any hair texture.
