Get answers to common questions about Keratin Complex Treatment.

Most clients enjoy smoother, softer hair for two to five months. Longevity depends on hair type, lifestyle, and aftercare. Using sulfate-free shampoos and minimizing frequent washing helps preserve the treatment and extend results.

Yes. The Keratin Complex Treatment is formulated to be safe on color-treated and highlighted hair and can help seal the cuticle to retain color. Your stylist will assess condition and recommend timing for optimal, damage-free results.

We recommend waiting 48 to 72 hours before shampooing to allow the keratin to fully set. Avoid tying hair or heavy moisture during this period. Afterward, use salon-recommended sulfate-free products to maintain the effect.

The treatment reduces curl and frizz and relaxes wave patterns, but may not produce pin-straight hair for very tight curls. Results vary by texture; discuss your desired look with your stylist for a tailored outcome.

Appointments typically last between one and three hours depending on hair length, thickness, and prior chemical services. Your stylist will provide a precise time estimate during your consultation and tailor the process to your needs.

Use sulfate-free, keratin-safe shampoos and conditioners, plus occasional deep-conditioning masks. Avoid clarifying shampoos and high-alcohol styling products. We carry professional aftercare lines at Salon Greco and will recommend the best products for your hair.
