Get answers to common questions about Kertain Treatment.

Most clients enjoy smooth, frizz-free results for six to twelve weeks depending on hair porosity, texture, and maintenance. Using sulfate-free products and minimizing harsh shampoos or excessive heat will help extend the treatment's lifespan.

Yes. Our professional formulas are compatible with most color services when applied correctly. We usually perform keratin treatments after coloring or recommend a short wait. We also offer low-formaldehyde or formaldehyde-free options to protect hair integrity.

Arrive with clean, product-free hair and avoid heavy conditioners or oils. Your stylist may clarify shampoo to maximize keratin absorption. Plan for a consultation on hair history, allergies, and your desired level of smoothing before starting.

The treatment primarily smooths and reduces frizz while providing some straightening depending on natural texture. Curly hair may relax and become looser; wavy hair will appear significantly smoother. Discuss your expected outcome with your stylist.

Use sulfate-free shampoo and conditioner, avoid washing for the first 48–72 hours, and limit chlorine or saltwater exposure. Use heat protectant when styling and schedule touch-ups as needed to maintain results and hair health.

We generally avoid combining color, relaxers, or perms in the same appointment to prevent unpredictable results. Your stylist will recommend the safest timeline or sequence, often scheduling services on different days for optimal outcomes.
