Frequently Asked Questions
Get answers to common questions about Keratin Treatment.

Yes, it's generally safe for color-treated hair and can enhance color vibrancy by smoothing cuticles. Timing matters—ideally wait two weeks after coloring. Tell your stylist about previous services so we can adjust the formula and protect your color.
Sessions usually take between ninety minutes and three hours depending on hair length, thickness, and condition. Consultation and preparation add time; expect longer appointments for very long or textured hair to ensure even application and optimal results.

Most clients are good candidates, but we assess hair health, recent chemical services, and scalp condition first. Pregnant clients or those with severe damage may need alternatives. Book a consultation so we can recommend the safest, most effective option.
No, keratin treatments are semi-permanent: they smooth and relax the curl pattern but don't permanently change texture. New growth returns to its natural state over time, and effects typically last weeks to months depending on care.
