Keratin Smoothing Treatment FAQs

A keratin smoothing treatment is a professional salon service that helps reduce frizz, improve shine, and make hair easier to manage. Rather than permanently straightening your hair, it smooths the outer layer of the hair while maintaining much of your natural texture.

An Express Keratin Treatment typically lasts about 4–6 weeks, while a Full Keratin Smoothing Treatment generally lasts between 3–5 months. Results vary based on your hair type, how often you shampoo, and the products you use at home. Sulfate-free products can help extend your results.

Not necessarily. Keratin smoothing treatments are designed to reduce frizz and soften your natural texture rather than permanently straighten your hair. Your stylist will customize the treatment based on whether your goal is smoother curls, softer waves, or a sleek finish.

In many cases, yes. Depending on your hair goals and color service, your stylist may recommend performing your color service before your keratin treatment for optimal results. During your consultation, we’ll create the best schedule for both services.

To keep your hair smooth and extend the life of your treatment, we recommend using professional sulfate-free shampoo and conditioner, minimizing exposure to chlorine when possible, and following the personalized home-care recommendations provided by your stylist. Proper aftercare helps your results stay beautiful for as long as possible.
