What Is a Keratin Smoothing Treatment?

A keratin smoothing treatment is a salon service that coats the hair with a protein-based formula and seals it with heat. It smooths the cuticle, reducing frizz and puffiness, so hair dries faster and stays sleek in humidity. Results typically last several months, fading gradually as you wash.

Keratin doesn’t have to make hair pin-straight. Curly and wavy clients often keep their natural pattern with far less frizz, while straighter hair becomes glossy and easy to blow out in minutes.

It’s one of our most transformative services — and one of the longest. Plan for a dedicated appointment, and we’ll walk you through aftercare so your results last as long as possible.

Keratin Treatment FAQs

How long does a keratin treatment last?

Most keratin treatments last about three to five months, depending on your hair type and how often you wash. Sulfate-free shampoo helps results last longer.

Plan on roughly two and a half to three and a half hours, depending on the length and thickness of your hair.

Keratin smooths frizz and loosens curl, but most curly clients keep some natural texture. If you blow-dry, your hair will straighten much faster and smoother.

Yes. We recommend coloring first, then keratin, so the treatment seals in your color. Your stylist can advise on scheduling both.

Follow your stylist’s aftercare instructions, use sulfate-free shampoo and conditioner, and avoid excessive clarifying products to keep your results smooth.
