Can You Get Highlights if You Have a Keratin Treatment?

If you've been enjoying the smoothness of a keratin treatment but find yourself craving a little dimension with highlights, you're not alone. This is one of the most common questions clients ask at Ka Belly Salon, and it's a great one. The short answer is yes, you absolutely can have both. But timing and sequencing make all the difference. Whether you're new to coloring after keratin treatment or just trying to understand how to plan your services, this guide walks you through everything you need to know.

Why You Can't Always Do Both Services on the Same Day

Keratin treatments work by coating each strand with a layer of protein that smooths the cuticle, reduces frizz, and gives hair that sleek, polished finish. That coating is exactly what makes the treatment so effective, but it also creates a barrier that can interfere with how hair color behaves.

When you apply highlights or any color formula over freshly treated hair, the keratin layer can block the color from fully penetrating the strand. This means your highlights may come out uneven, dull, or significantly less vibrant than expected. Stylists with experience in coloring after keratin treatment understand this chemistry well: it's not about the color being weak, it's about the hair being temporarily resistant to it.

The general professional guideline is to wait at least two weeks after a keratin treatment before applying any color service. This window gives the treatment time to fully bond to the hair structure and stabilize. After that stabilization period, color can penetrate more evenly and deliver the results you're actually after.

Which Should Come First: Color or Keratin?

This is where the sequencing conversation gets really important. If you're planning to get both services, the ideal order is: color first, then keratin treatment. Here's why that order works better for your hair.

When highlights are applied to natural or previously colored hair, the lightener can lift and deposit color freely without any barriers. Once the color is complete and your hair looks exactly how you envisioned, a keratin treatment applied afterward actually seals the color molecules into the cuticle: meaning your highlights can look even shinier and last longer than they would without the treatment.

The reverse, keratin first, then color, isn't impossible, but it does come with trade-offs. Even when you wait the recommended two weeks, expect the coloring process to reduce some of the keratin's smoothing effect, typically by around 10 to 20 percent. You may notice slightly more frizz in the weeks following color if keratin was applied first. It's not dramatic, but it's worth knowing before you book both appointments back to back.

At Ka Belly Salon, we always talk through your full hair goals before recommending a service order. Getting highlights and a keratin treatment in the right sequence makes a real difference in the final result.

What Happens to Color Vibrancy After a Keratin Treatment?

Here's something many clients don't realize: even when timing is perfect, a keratin treatment applied after color can slightly mute the tone of your highlights. The protein coating that makes the treatment work can sometimes create a subtle film over the hair, which may soften the brightness of lighter shades like honey blondes or caramel tones.

This doesn't mean your color will look bad: it often still looks beautiful. But if you're expecting super high-contrast, vivid highlights, you may notice they appear slightly more toned down post-keratin. For clients with dark skin tones who are selecting warm, rich highlights to complement their complexion, this can actually work in your favor by keeping the color soft and wearable rather than stark.

The solution is straightforward: communicate your color goals clearly before any service begins. When your stylist knows you want both highlights and a keratin treatment, she can factor in your desired end result and choose a color formula that accounts for any potential muting, ensuring you still walk out looking exactly how you imagined.

How Ka Belly Salon Handles Clients Who Want Both Services

At Ka Belly Salon, we see clients regularly who come in with chemically processed hair, including keratin treatments, relaxers, and color history, and want to layer on highlights without compromising their hair's health or their existing treatments. Our approach is always personalized.

During your consultation, we look at your hair's current condition, how recently you had your keratin treatment applied, and what kind of highlights you're hoping to achieve. From there, we map out a realistic and safe plan. For most clients, this means:

• Confirming at least a two-week gap between keratin and any color service
• Recommending a deep conditioning treatment before highlights if the hair needs added strength
• Selecting a lightener and developer combination appropriate for your hair's current porosity
• Adjusting the tone of your highlights to account for any post-keratin softening
• Spacing out appointments strategically so both services can deliver their full effect

If you're also navigating relaxed hair alongside a keratin treatment, some of the same sequencing principles apply, and our post on chemical hair damage signs covers what to watch for when combining multiple chemical services.

The goal is always beautiful, healthy-looking hair that reflects your personal style, not a rushed service that leaves your hair compromised.

Frequently Asked Questions

How long should I wait to color my hair after a keratin treatment?

Most professional stylists recommend waiting a minimum of two weeks after a keratin treatment before applying any color service, including highlights. This allows the keratin to fully bond and stabilize within the hair structure so that color can penetrate evenly and achieve the best results.

Will highlights ruin my keratin treatment?

Highlights applied after a keratin treatment can reduce some of the smoothing effect, typically around 10 to 20 percent, which may result in slightly more frizz over time. However, with proper timing and professional application, your highlights will not completely undo your keratin treatment. Planning the sequencing correctly minimizes any impact on either service.

Can I get a keratin treatment and highlights on the same day?

It is not recommended to combine these two services in the same appointment. Applying color over freshly applied keratin can prevent the color from absorbing properly, leading to uneven or less vibrant results. For the best outcome, schedule the two services at least two weeks apart.

Which is better for dark skin tones: highlights before or after keratin?

For clients with dark skin tones who want warm, dimensional highlights, it's generally better to get color first and then follow up with a keratin treatment. This order allows the highlights to lift and develop fully, and the keratin treatment afterward can actually seal the color and enhance shine. Your stylist can recommend the best timing based on your hair's current condition and your color goals.
