Keratin Smoothing and Color: Which One Should Come First?

Elena, owner and stylist at Elleven Hair StudioBy Elena

Quick Answer: Color first, then wait about two weeks before booking keratin smoothing — this lets the color cuticle close and keeps the two treatments from interfering with each other. Keratin second also helps seal in and extend the color underneath. Doing them in the same week, or keratin before color, risks patchy color and a shorter-lasting smoothing result.

A lot of clients want a fresh color and a keratin smoothing treatment around the same visit, especially heading into a new season. It’s a fair ask, but the order actually matters. Get the sequence backwards and you can end up with color that fades faster than it should, a keratin treatment that doesn’t take evenly, or both results falling short of what you paid for.

Color First, Then Keratin, With Some Time Between

The general rule I follow is to color first and let it settle for about two weeks before booking a keratin smoothing treatment. Freshly colored hair needs time for the cuticle to close back down, and a keratin treatment applied too soon can interfere with how the color continues to develop. Doing keratin second has a real upside too: the smoothing treatment seals the cuticle, which helps lock in the color underneath and can actually extend how long it stays vibrant — especially if you follow the right keratin aftercare routine in the days right after.

Why Coloring Right After Keratin Is the Riskier Order

Flipping the order is where things tend to go sideways. A fresh keratin treatment coats the hair shaft, and that coating can make color grab unevenly, leaving patchier or duller results than you’d get on untreated hair. Coloring too soon can also strip some of the keratin treatment before it’s had a chance to fully bond, which shortens how long the smoothing results last. If you need a color touch-up soon after a keratin treatment, waiting several weeks and using a gentler, lower-ammonia formula gives both a better shot at holding up.

One Appointment or Two?

These aren’t usually same-day services, no matter which one comes first. The chemistry in both treatments needs room to settle, so I typically map out a two-visit plan: color first, then keratin about two weeks later, timed around when your roots need touching up anyway. If you’re only after a subtle refresh, a semi-permanent or gloss treatment can sometimes fit into a tighter window than a full color change.

How I Plan Both Visits

  • Visit 1, color or balayage. We start with a CA$15 consultation. A full-head balayage starts at CA$500 and takes about 5 hours. Balayage in Langley
  • Visit 2, about two weeks later, keratin smoothing. It starts at CA$390 and takes about 4 hours. Keratin smoothing in Langley

Final prices depend on your hair length and thickness, and I confirm them at your consultation.

What About Highlights or Balayage Specifically

Highlights and balayage follow the same color-first rule, but with one added wrinkle: lightening is more chemically intensive than an all-over color, so hair coming out of a balayage or highlight service may need slightly more than two weeks to fully recover before a keratin treatment, especially if the lift was significant. This is exactly the kind of detail worth flagging at your consultation — how much lightening happened, and how your hair responded to it, both factor into how much settling time makes sense before adding keratin on top.

If you’re weighing both services, bring it up at your next visit. I can look at your current color, how much lift you’re planning, and how soon you want the frizz gone, then build a timeline that protects both instead of rushing them into the same week. Still deciding whether keratin smoothing is right for your hair in the first place? That’s worth settling before the color conversation even starts.
