Frequently Asked Questions

Get answers to common questions about K18 Treatment.

K18 Treatment reconnects disrupted keratin chains at the molecular level, reversing damage from chemicals, heat, and environment. Clients typically notice improved strength, softness, and elasticity after one application; a short series is recommended for severely compromised hair to maximize restoration.

Results vary by hair porosity and maintenance; many clients enjoy repaired feel for several weeks to months. Regular cleansing and mechanical stress gradually reduce effects. For lasting benefit, follow salon recommendations, use K18 home products, and schedule occasional in-salon refresh treatments.

Yes — K18 Treatment is compatible with color-treated and lightened hair and is often used to repair damage from coloring or bleaching. Your stylist will assess timing; sometimes applying K18 between chemical services or after processing yields the best restorative results.

Yes — K18 can be integrated into many salon protocols, but timing matters. Stylists often apply it after chemical services like lightening or coloring to repair bonds, or between appointments for maintenance. Your technician will recommend the safest sequence for optimal repair and color results.

Most clients can style hair right after the K18 Treatment, but we recommend using a heat protectant and moderate temperatures to preserve repaired bonds. Excessive high heat may stress hair; consult your stylist for personalized heat settings based on hair condition.

K18 technology is formulated to benefit all hair types and textures — fine, coiled, straight, or color-treated. Effectiveness depends on the extent of damage; our stylists will evaluate your hair and design a tailored plan, sometimes recommending a series for deeper restoration.
