That 80% humidity day that turns your sleek ponytail into a puffball? A smoothing treatment laughs at humidity.
Freezing cold outside, roasting hot inside. Your hair expands and contracts like a sponge. Smoothing treatments stabilize the cuticle so it doesn’t react to every temperature change.
Most New Yorkers rely on blow-dryers, flat irons, and curling wands. Smoothing cuts styling time in half: your hair air-dries smoother and needs less heat to look polished.
Pollution, hard water, wind, indoor heating. Your hair absorbs all of it. Keratin treatments create a barrier that protects against environmental damage.
All three systems are safe on color-treated hair and actually help color last longer by sealing the cuticle.
We offer three premier smoothing systems, each with a different approach and different strengths. Your stylist will help you choose the right one based on your hair type, texture, and goals.
Keratin Complex Natural Smoothing — All hair types, from fine and straight to thick and curly. Significant frizz reduction with minimal change to your natural texture, and up to 50% less blow-dry time. About 90 minutes.
NKST — Damaged, color-treated, or chemically processed hair that needs smoothing and repair in one service. About 90 minutes; lasts up to 5 months.
Peter Coppola — Extreme frizz, coarse texture, or unruly waves, with the fastest in-salon process: about 75 minutes. Formaldehyde- and aldehyde-free; lasts up to 3 months.
All three — $350–$450, safe on color, and a 72-hour wait before your first wash.

Keratin and smoothing treatments are professional in-salon services that infuse your hair with a protective protein coating, smoothing the cuticle, reducing frizz, and creating long-lasting manageability. The result is hair that’s softer, shinier, easier to style, and dramatically less reactive to humidity.
These are not chemical straighteners. You won’t lose your wave pattern or curl texture (unless you want to). Think of it as a reset button for your hair’s surface: it smooths the cuticle without changing your hair’s fundamental shape.
With proper maintenance, results last up to 5 months, depending on the system, making smoothing one of the best investments you can make for low-maintenance, high-impact hair in New York City.
Now imagine stepping off that subway grate and your hair still looks smooth. Just sleek, shiny, manageable hair that does what you want it to do, regardless of the weather.
Your stylist examines your hair (texture, porosity, damage level, color history) and recommends the best treatment for your needs. We don’t upsell you on the most expensive option; we match you to the right system.
A clarifying shampoo removes buildup from products, minerals, and oils, and opens the cuticle so the keratin formula can penetrate.
The formula is applied section by section and saturated through your hair from roots to ends. Your stylist works it through for even coverage.
The formula stays on for a set time that varies by system and hair type. Heat is applied to seal the keratin into the hair cuticle.
Your hair is blow-dried and flat-ironed in small sections to lock in the treatment. This is where you’ll see the results take shape: smooth, shiny, transformed.
For 72 hours, you can’t wash your hair, pull it back tightly, or get it wet. After that, you’re free: wash, style, and live your life with dramatically smoother, frizz-free hair.
Not unless you want to. Keratin Complex and NKST are smoothing treatments, not straighteners. Your natural wave or curl will still be there, just smoother, softer, and less frizzy. If you want straighter hair, your stylist can flat iron straighter during the processing phase.
Yes. All three systems are safe on color and actually help color last longer by sealing the cuticle. NKST, which also helps repair damage, is our go-to for hair that’s been through years of color.
Keratin Complex lasts 3 to 5 months, NKST up to 5 months, and Peter Coppola up to 3 months. Sulfate-free shampoo and conditioner extend your results; we carry IGK and Milbon at the salon.
Yes, but we recommend coloring first, then smoothing. If you want both, we’ll discuss the best sequence during your consultation.
It will dramatically improve the look and feel of heat-damaged hair by smoothing the cuticle, and NKST also helps repair damage. Severely heat-damaged hair may need multiple treatments or K18 bond repair.
You can air-dry with significantly better results than untreated hair. For a polished, styled look you’ll still need heat, but styling takes half the time and holds much better.
