Peekaboo Highlights: The Ultimate Guide to Hidden Hair Color

In the ever-evolving world of hair fashion, versatility is the ultimate luxury. For years, clients have had to choose between conservative, professional looks and bold, expressive colors. However, one trend has successfully bridged this gap, offering the best of both worlds: Peekaboo Highlights. Also known as "hidden highlights" or "underlights," this technique involves coloring the bottom layer of hair while leaving the top layer natural. The result is a pop of color that reveals itself only when the hair moves, is tucked behind the ear, or is styled in an updo.

As we move into 2026, peekaboo highlights remain a dominant force in salon requests, evolving from simple blonde streaks to complex, multi-tonal masterpieces. Whether you are looking for a subtle shimmer of rose gold or a shocking electric blue, this style offers a low-commitment way to experiment with color without altering your entire appearance. This comprehensive guide explores everything you need to know about peekaboo highlights, from the technical application process and trending color combinations to essential maintenance tips for keeping your hidden hues vibrant.

What Exactly Are Peekaboo Highlights?

Peekaboo highlights are a coloring technique where dye is applied to the underneath layers of the hair, specifically the section at the nape of the neck or just above the ears. Unlike traditional foils or balayage, which aim to blend color throughout the entire head for a sun-kissed or dimensional look, peekaboo highlights are designed to be concealed by the top layer of hair (the "canopy"). The name comes from the game "peekaboo," as the color is often hidden until the hair is manipulated.

Technically, this style falls under the category of "block coloring" or "paneling." A stylist will section off the top crown of the hair—usually the part, the bangs, and the layers immediately surrounding the face—and clip it out of the way. The color is then applied to the remaining hair underneath. This can be done in foils for lift and precision, or painted on directly for a more saturated block of color. Because the top layer remains untouched, the regrowth is virtually invisible, making this one of the most forgiving color techniques available.

What makes this technique truly unique is the element of surprise. When wearing hair down and straight, the color might be completely invisible or appear as a faint shadow, adding depth. However, a simple hair flip, a breeze, or tying the hair into a half-up, half-down style instantly transforms the look from business-casual to creative and edgy. It is the chameleon of hair color techniques, adaptable to every lifestyle and profession.

Why Choose Peekaboo Highlights Over Traditional Color?

The Low-Maintenance Factor

One of the most significant advantages of peekaboo highlights is the minimal upkeep required compared to full-head color or traditional roots-to-ends highlights. With standard highlighting, root regrowth becomes visible within 4 to 6 weeks, creating a harsh line of demarcation that requires frequent salon visits. With peekaboo styles, the colored section is covered by your natural hair. As the roots grow out, they are hidden underneath the top layer, meaning you can go months without a touch-up. This makes it an ideal choice for budget-conscious individuals or those with busy schedules who cannot commit to monthly salon appointments.

Protecting Hair Integrity

Chemical processing, particularly bleaching, inevitably takes a toll on hair health. Full-head bleaching can lead to dryness, breakage, and loss of elasticity if not managed correctly. Peekaboo highlights significantly reduce the amount of hair being processed. Since only the bottom layer or specific sections are lightened and colored, the majority of the hair—specifically the fragile top layers which are most exposed to sun and heat damage—remains in its natural, healthy state. This allows clients to enjoy vibrant colors while maintaining the overall integrity and shine of their mane.

Professional Versatility

Despite changing workplace norms, many corporate environments still have strict dress codes regarding "unnatural" hair colors. Peekaboo highlights offer a clever workaround. Because the color is located on the interior of the haircut, it can be easily concealed during office hours by wearing the hair down. Once the workday is over, styling the hair up or curling it reveals the vibrant tones underneath. It allows for personal expression without compromising professional standards, effectively providing two distinct hairstyles in one.

Trending Color Combinations for 2026

The High-Contrast Platinum

For those with naturally dark brown or black hair, nothing makes a statement quite like platinum blonde peekaboo highlights. The stark contrast between the deep natural base and the icy white underlayer creates a dramatic, edgy aesthetic. This monochromatic look is timeless and pairs exceptionally well with blunt bobs or long, straight styles where the separation of color is distinct. It adds immediate visual interest and dimension without the need for rainbow colors.

The "Oil Slick" and Jewel Tones

Inspired by the iridescent colors seen in spilled oil, this trend utilizes deep violets, emerald greens, and midnight blues. These shades are particularly stunning on brunette hair as they do not always require lifting the hair to a level 10 platinum blonde before application. Jewel tones are rich, sophisticated, and tend to fade more gracefully than pastels, often washing out to muted, vintage hues that still look intentional. This is a favorite for autumn and winter seasons.

Pastel Unicorn and Cotton Candy

For lighter hair types or those willing to undergo significant lightening, pastel peekaboos remain a massive trend. Soft pinks, baby blues, lavenders, and mint greens create a whimsical, fairy-tale vibe. Because these colors are hidden, they offer a subtle way to participate in the "fantasy hair" trend without feeling overwhelmed by color. A popular variation is the "holographic" underlight, where multiple pastel shades are melted together in the underlayer to create a shifting, prismatic effect.

Fiery Red and Copper

Red has been the breakout color of the mid-2020s. Adding a block of bright copper, ruby red, or cherry cola underneath warm brown hair adds incredible warmth and vibrancy. This combination feels organic yet bold. When the hair is curled, the red ribbons mix with the brunette to create a flame-like effect that is incredibly striking. It is a perfect entry point for those wanting to experiment with warm tones without coloring their entire head red.

Peekaboo Highlights for Different Hair Textures

Straight and Fine Hair

On straight, fine hair, peekaboo highlights can create the illusion of thickness and depth. The color acts as a shadow or a highlight (depending on the tone chosen) that gives the hair more dimension. However, placement is critical here. Because fine hair moves more fluidly, the color may peek through more often. Stylists often opt for thinner slices of color rather than large blocks to ensure the top layer provides adequate coverage.

Wavy and Curly Hair

Textured hair is arguably the best canvas for peekaboo highlights. The natural movement of waves and curls allows the hidden color to weave in and out of the natural hair, creating a stunning, blended effect. When curly hair shrinks, the placement of the color may appear higher up than when wet, so experienced stylists will account for shrinkage when applying the lightener. Curly peekaboos look exceptional when the hair is refreshed and voluminous, appearing as bursts of color within the texture.

Short Hair and Bobs

Short hair requires strategic placement. With a bob or a lob (long bob), the peekaboo section is often placed from the temple down to the nape. This ensures that when the hair is tucked behind the ear—a common habit for bob wearers—the color is revealed. For very short pixie cuts, peekaboo highlights can be placed in the fringe or the longer layers of the crown, offering a pop of color that adds texture to the cut.

The Salon Experience: What to Expect

The Consultation

Every great color service begins with a consultation. During this phase, you will discuss your desired color, the level of visibility you want, and your hair history. Be honest about previous color treatments, as this affects how well the lightener will lift your hair. Bring reference photos to show exactly where you want the color to start and how much of it you want to see.

The Lightening Process

Unless you are depositing a color darker than your natural shade, bleaching is almost always required for peekaboo highlights. To get vibrant blues, pinks, or platinum, the underlying hair must be lifted to a pale yellow. The stylist will section away your top layer and apply lightener to the bottom section. Depending on your hair's starting darkness, this can take anywhere from 30 minutes to an hour. Bond builders (like Olaplex or K18) are often added to the bleach to prevent damage.

Color Application

Once the hair is lightened and rinsed, the hair is dried, and the target color is applied. This is where the magic happens. If you are opting for a rainbow or multi-tonal look, the stylist will carefully paint different strands, separating them with foil or plastic wrap to prevent bleeding. The color processes for about 20 to 30 minutes before being rinsed with cool water.

Toning and Styling

After the color is rinsed, a toner might be applied to the rest of the hair to ensure the tone matches the new highlights (e.g., cooling down a brunette top layer to match an ash-blonde underlayer). Finally, the hair is blown out and styled. This is the big reveal—the moment you see the hidden color transform your look.

Essential Maintenance and Aftercare

Maintaining the vibrancy of peekaboo highlights requires a dedicated home care routine. Fashion colors (reds, blues, pinks) are semi-permanent and sit on top of the hair cuticle, meaning they fade with every wash. To prolong the life of your color, wash your hair less frequently—2 to 3 times a week is ideal. Use dry shampoo in between washes to keep the top layer fresh.

Temperature Matters: Always wash your hair with cool or lukewarm water. Hot water opens the hair cuticle, allowing color molecules to escape rapidly. Cold water helps seal the cuticle, locking in the color and adding shine. While a cold shower isn't pleasant, even a cool rinse at the end can make a significant difference.

Product Selection: Switch to sulfate-free, color-safe shampoos and conditioners. Sulfates are harsh detergents that strip natural oils and color from the hair. Additionally, consider using a color-depositing conditioner once a week. These products contain small amounts of pigment that refresh your color in the shower, keeping it bright between salon visits.

Heat Protection: Heat styling is a major enemy of hair color. High temperatures can scorch the hair and cause color to fade instantly (especially pastels). Always apply a high-quality heat protectant spray before using blow dryers, curling irons, or straighteners. Lower the temperature setting on your tools; you rarely need the highest setting to achieve your desired style.

Frequently Asked Questions (FAQ)

Q1: How much do peekaboo highlights typically cost? A: The cost varies significantly by salon location and the complexity of the color. Generally, because it involves less hair than a full head of highlights, it is cheaper. Expect to pay anywhere from $100 to $250. This usually includes lightening, coloring, and styling. Multi-colored or intricate designs will cost more.

Q2: Will peekaboo highlights damage my hair? A: Any chemical service carries some risk, but peekaboo highlights are among the least damaging options because they only affect the bottom layer of hair. The top layer remains virgin (untreated), maintaining the overall healthy appearance of your hair. Using bond-building treatments during the service further minimizes damage.

Q3: Can I get peekaboo highlights on black hair without bleach? A: If you want vibrant colors (pink, blue, blonde) or copper, bleach is necessary to lift the black pigment so the new color can show. However, if you want a subtle look, you can use high-lift permanent color to achieve shades like dark cherry or mahogany without traditional bleach, though the result will be more understated.

Q4: How long do the colors last? A: This depends on the dye used. Permanent colors (like natural browns or reds) can last until they grow out. Semi-permanent fashion colors (pastels, neons) typically last 4 to 8 weeks depending on washing frequency. Pastels fade the fastest, while deeper blues and greens last longer.

Q5: Can I hide peekaboo highlights in a ponytail? A: It depends on the placement. If the highlights are placed strictly at the nape of the neck, they will be very visible in a high ponytail. If you need them to be hidden even when tied up, ask your stylist to keep the color away from the immediate hairline at the neck, or opt for a low bun where the colored ends can be tucked away.

Q6: Are peekaboo highlights suitable for older women? A: Absolutely. Peekaboo highlights are ageless. Many women with grey hair use peekaboo lowlights (darker colors underneath) to add depth, or fun splashes of lavender or silver to embrace their natural transition with a modern twist. It’s a fun, youthful way to accessorize hair at any age.

Conclusion

Peekaboo highlights represent the perfect synergy of professional restraint and creative expression. They offer a unique way to personalize your look without the heavy maintenance or potential damage associated with full-head transformations. Whether you are looking to dip your toes into the world of hair color for the first time or are a seasoned enthusiast looking for a versatile new style, peekaboo highlights are a customizable, stylish, and practical choice.

As we navigate the trends of 2026, the emphasis is on individuality and hair health—two things this technique prioritizes.
